-This is a list of random notes for GRUB maintainers. If you are not a
-maintainer, you need to ask maintainers to do these instead of doing
-these yourself.
-
-How to update the online manual: (FIXME: this is obsoelete)
-1. Copy docs/*.texi (excluding "multiboot.texi") to fencepost.gnu.org.
-2. Make a symbolic link from ~mohit/gnudoc/gnudoc_template to the
- directory under which *.texi were copied, if the link isn't present.
-3. Run ``~mohit/gnudoc/gendocs.sh grub "GNU GRUB Manual"''.
-4. Copy the contents of the directory ``manual'' to
- gnudist.gnu.org:~ftp/gnu/Manuals/grub-VERSION (VERSION is, for
- example, 1.0).
-5. Run ``ln -sf grub-VERSION grub'' in gnudist.gnu.org:~ftp/gnu/Manuals.
-6. Run ``cd grub; ln -s grub.html index.html''.
-7. Verify the new online manual with a WWW browser.
-8. Update manual.html by hand.
-
-How to release a version:
-1. Check out the source tree from the CVS from scratch.
-2. Check if ``make distcheck'' succeeds.
-3. Run ``util/grub-image''.
-4. Check the resulted images, for example, using bochs.
-5. Copy grub-VERSION.tar.gz, grub-VERSION-i386-pc.tar.gz and
- grub-VERSION-i386-pc.ext2fs to fencepost.gnu.org:~ftp/gnu/grub.
-6. Move older files in that directory above to the directory ``old'',
- if you think they are eyesores.
-7. Post an announcement to bug-grub@gnu.org. It would be a good idea to
- send a carbon copy to bug-hurd@gnu.org and
- debian-hurd@lists.debian.org. If the announcement is for a stable
- version, you can inform info-gnu@gnu.org as well.
-8. Optionally, post an announcement to Freshmeat.net.
-
-Legal issues:
-1. If a patch is not significant (in size), you don't have to care about
- the copyright.
-2. If a patch is significant, you shouldn't apply the patch to the CVS.
- Before doing that, you must ask the contributor to assign or disclaim
- the copyright. Send ``/gd/gnuorg/request-assign.changes'' or
- ``/gd/gnuorg/request-assign.future'' to the contributor, and wait
- until the FSF finishes the legal work.
-3. You can check if a contributor has already assigned his/her copyright
- to the FSF by looking at ``/gd/gnuorg/copyright.list''.
-
-What you should have in your mind:
-1. Don't add features unnecessarily! You may think it is a Good Thing to
- have more features, but you must be prepared for more burdens.
- DO THAT ONLY IF YOU BELIEVE THAT THE FEATURE IS ESSENTIAL.
-2. Don't break backward-compatibility! Don't apply any patch which could
- break existing features. Otherwise you would receive a lot of
- complaints. DO THAT ONLY IF YOU BELIEVE THAT THE INCOMPATIBILITY IS
- INEVITABLE.
-3. Write good code. Be not satisfied with ad hoc workarounds or quick
- hacks. NEVER WRITE BAD CODE.

-Before working on anything in this file, it's very important that you
-make contact with the core GRUB developers. Things herein might be
-slightly out of date or otherwise not easy to understand at first
-glance. So write to <bug-grub@gnu.org> first.
-
-Priorities:
- Reported bugs generally have top priority.
- Non-reported and non-encountered bugs (things we know don't work,
- but don't really impede things) have lower priority.
- Things in this file are ranked with one to three !; the more, the
- higher priority.
-
-
-Things that should be done before 1.0:
-
-* Finish the Multiboot Speicification 0.7. !!!
-
-* Add more --disable-FOO options to configure, so that you can create a
- minimum GRUB image. This is useful for boot floppies because of the size
- restriction. !
-
-* Implement a new version of track_int13, using Virtual 8086 Mode. !!!
-
-* Add missing features of graphics support. !!
-
-Things that should _not_ be done before 1.0:
-
-* Add configuration inclusion support by adding a command "include". !
-
-* Add automatic configuration support.
-
-* Add bunzip2 support.
-
-* Define the module system.
-
-* Add BSD syntax support, using results of ioprobe to map drives. !
- (0x1f0-0x1f7 = primary IDE, 0x170-0x176 = secondary,
- 0x1e8-0x1ef = tertiary, 0x168-0x16f = quaternary).
-
-* Add a real scripting language, possibly retaining backward
- compatibility so that old config files can be used.
-
-* Add internationalization support, emulating gettext as much as is
- feasible.
-
-* Support other architectures than i386-pc.
-
-* Add real memory management.
-
-
-Things that may be done anytime:
-
-* Port the script ``grub-install'' to OpenBSD. At least you will have to
- modify the function `convert' so that it can translate a native device
- name into the corresponding GRUB drive representation. !
-
-* Add a command to run a GRUB script file. !!
-
-* Add commands to manipulate the menu from the command-line interface. !
-
-* Make symbolic links work for BSD FFS.
-
-* Add indirect block support to the BSD FFS filesystem code, so files
- larger than 16MB can be read.
-
-* Fix-up FreeBSD, NetBSD (and OpenBSD ?) command-line boot
- parameters.
-
-* Support embedding a Stage 1.5 in the "bootloader" area of a FFS
- partition. (We already have the code, but need an approval by an
- expert before turning on the support. Any volunteers?)
-
-* Support embedding a Stage 1.5 in the EXT2_BOOT_LOADER_INO of an ext2fs
- partition, so that it won't be accidentally erased or modified by
- the kernel.
-
-* Add ISA PnP support.
-
-* Add more filesystems support (NTFS, etc.)
-
-* Add more remote console support (parallel and net).
-
-* Add (real) RAID support.
-
-? Add a partition naming syntax that means ``the first partition of
- this type''. We need this for clean Hurd install floppies.
- Nope. Improving the `find' command would solve this problem.
-
-* Add CDROM-chainloading support. It would be enough to support only
- BIOSes which have bootable-CDROM support (so you may use the "Bootable
- CDROM" BIOS calls). It is not trivial to support BIOSes without the
- capability to boot CDROM.
-
-? Divide pxegrub into two parts, so the initial image doesn't exceed
- the 32KB limit. I'm not sure if this is really necessary, because the
- PXE standard just says that it is _recommended_ to improve the
- modularity of a boot image. Obviously, this reason doesn't apply to
- GRUB, as pxegrub is merely a secondary boot loader. So whether this
- task should be done depends on if existing PXE ROMs support >32KB
- images or not, after all.

-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
-# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory. The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run. This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-# fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-# fails if $ac_aux_dir is absolute,
-# fails when called from a subdirectory in a VPATH build with
-# a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir. In an in-source build this is usually
-# harmless because $srcdir is `.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
-# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-# MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because

-@node Overview
-@section Overview
-
-Briefly, a @dfn{boot loader} is the first software program that runs when
-a computer starts. It is responsible for loading and transferring
-control to an operating system @dfn{kernel} software (such as Linux or
-GNU Mach). The kernel, in turn, initializes the rest of the operating
-system (e.g. a GNU system).
-
-GNU GRUB is a very powerful boot loader, which can load a wide variety
-of free operating systems, as well as proprietary operating systems with
-chain-loading@footnote{@dfn{chain-load} is the mechanism for loading
-unsupported operating systems by loading another boot loader. It is
-typically used for loading DOS or Windows.}. GRUB is designed to
-address the complexity of booting a personal computer; both the
-program and this manual are tightly bound to that computer platform,
-although porting to other platforms may be addressed in the future.
-
-One of the important features in GRUB is flexibility; GRUB understands
-filesystems and kernel executable formats, so you can load an arbitrary
-operating system the way you like, without recording the physical
-position of your kernel on the disk. Thus you can load the kernel
-just by specifying its file name and the drive and partition where the
-kernel resides.
-
-When booting with GRUB, you can use either a command-line interface
-(@pxref{Command-line interface}), or a menu interface (@pxref{Menu
-interface}). Using the command-line interface, you type the drive
-specification and file name of the kernel manually. In the menu
-interface, you just select an OS using the arrow keys. The menu is
-based on a configuration file which you prepare beforehand
-(@pxref{Configuration}). While in the menu, you can switch to the
-command-line mode, and vice-versa. You can even edit menu entries
-before using them.
-
-In the following chapters, you will learn how to specify a drive, a
-partition, and a file name (@pxref{Naming convention}) to GRUB, how to
-install GRUB on your drive (@pxref{Installation}), and how to boot your
-OSes (@pxref{Booting}), step by step.
-
-Besides the GRUB boot loader itself, there is a @dfn{grub shell}
-@command{grub} (@pxref{Invoking the grub shell}) which can be run when
-you are in your operating system. It emulates the boot loader and can
-be used for installing the boot loader.
-
-
-@node History
-@section History of GRUB
-
-GRUB originated in 1995 when Erich Boleyn was trying to boot the GNU
-Hurd with the University of Utah's Mach 4 microkernel (now known as GNU
-Mach). Erich and Brian Ford designed the Multiboot Specification
-(@pxref{Top, Multiboot Specification, Motivation, multiboot, The Multiboot
-Specification}), because they were determined not to add to the large
-number of mutually-incompatible PC boot methods.
-
-Erich then began modifying the FreeBSD boot loader so that it would
-understand Multiboot. He soon realized that it would be a lot easier
-to write his own boot loader from scratch than to keep working on the
-FreeBSD boot loader, and so GRUB was born.
-
-Erich added many features to GRUB, but other priorities prevented him
-from keeping up with the demands of its quickly-expanding user base. In
-1999, Gordon Matzigkeit and Yoshinori K. Okuji adopted GRUB as an
-official GNU package, and opened its development by making the latest
-sources available via anonymous CVS. @xref{Obtaining and Building
-GRUB}, for more information.
-
-
-@node Features
-@section GRUB features
-
-The primary requirement for GRUB is that it be compliant with the
-@dfn{Multiboot Specification}, which is described in @ref{Top, Multiboot
-Specification, Motivation, multiboot, The Multiboot Specification}.
-
-The other goals, listed in approximate order of importance, are:
-
-@itemize @bullet{}
-@item
-Basic functions must be straightforward for end-users.
-
-@item
-Rich functionality to support kernel experts and designers.
-
-@item
-Backward compatibility for booting FreeBSD, NetBSD, OpenBSD, and
-Linux. Proprietary kernels (such as DOS, Windows NT, and OS/2) are
-supported via a chain-loading function.
-@end itemize
-
-Except for specific compatibility modes (chain-loading and the Linux
-@dfn{piggyback} format), all kernels will be started in much the same
-state as in the Multiboot Specification. Only kernels loaded at 1 megabyte
-or above are presently supported. Any attempt to load below that
-boundary will simply result in immediate failure and an error message
-reporting the problem.
-
-In addition to the requirements above, GRUB has the following features
-(note that the Multiboot Specification doesn't require all the features
-that GRUB supports):
-
-@table @asis
-@item Recognize multiple executable formats
-Support many of the @dfn{a.out} variants plus @dfn{ELF}. Symbol
-tables are also loaded.
-
-@item Support non-Multiboot kernels
-Support many of the various free 32-bit kernels that lack Multiboot
-compliance (primarily FreeBSD, NetBSD, OpenBSD, and
-Linux). Chain-loading of other boot loaders is also supported.
-
-@item Load multiple modules
-Fully support the Multiboot feature of loading multiple modules.
-
-@item Load a configuration file
-Support a human-readable text configuration file with preset boot
-commands. You can also load another configuration file dynamically and
-embed a preset configuration file in a GRUB image file. The list of
-commands (@pxref{Commands}) are a superset of those supported on the
-command-line. An example configuration file is provided in
-@ref{Configuration}.
-
-@item Provide a menu interface
-A menu interface listing preset boot commands, with a programmable
-timeout, is available. There is no fixed limit on the number of boot
-entries, and the current implementation has space for several hundred.
-
-@item Have a flexible command-line interface
-A fairly flexible command-line interface, accessible from the menu,
-is available to edit any preset commands, or write a new boot command
-set from scratch. If no configuration file is present, GRUB drops to
-the command-line.
-
-The list of commands (@pxref{Commands}) are a subset of those supported
-for configuration files. Editing commands closely resembles the Bash
-command-line (@pxref{Command Line Editing, Bash, Command Line Editing,
-features, Bash Features}), with @key{TAB}-completion of commands,
-devices, partitions, and files in a directory depending on context.
-
-@item Support multiple filesystem types
-Support multiple filesystem types transparently, plus a useful explicit
-blocklist notation. The currently supported filesystem types are
-@dfn{BSD FFS}, @dfn{DOS FAT16 and FAT32}, @dfn{Minix fs}, @dfn{Linux
-ext2fs}, @dfn{ReiserFS}, @dfn{JFS}, @dfn{XFS}, and @dfn{VSTa
-fs}. @xref{Filesystem}, for more information.
-
-@item Support automatic decompression
-Can decompress files which were compressed by @command{gzip}. This
-function is both automatic and transparent to the user (i.e. all
-functions operate upon the uncompressed contents of the specified
-files). This greatly reduces a file size and loading time, a
-particularly great benefit for floppies.@footnote{There are a few
-pathological cases where loading a very badly organized ELF kernel might
-take longer, but in practice this never happen.}
-
-It is conceivable that some kernel modules should be loaded in a
-compressed state, so a different module-loading command can be specified
-to avoid uncompressing the modules.
-
-@item Access data on any installed device
-Support reading data from any or all floppies or hard disk(s) recognized
-by the BIOS, independent of the setting of the root device.
-
-@item Be independent of drive geometry translations
-Unlike many other boot loaders, GRUB makes the particular drive
-translation irrelevant. A drive installed and running with one
-translation may be converted to another translation without any adverse
-effects or changes in GRUB's configuration.
-
-@item Detect all installed @sc{ram}
-GRUB can generally find all the installed @sc{ram} on a PC-compatible
-machine. It uses an advanced BIOS query technique for finding all
-memory regions. As described on the Multiboot Specification (@pxref{Top,
-Multiboot Specification, Motivation, multiboot, The Multiboot
-Specification}), not all kernels make use of this information, but GRUB
-provides it for those who do.
-
-@item Support Logical Block Address mode
-In traditional disk calls (called @dfn{CHS mode}), there is a geometry
-translation problem, that is, the BIOS cannot access over 1024
-cylinders, so the accessible space is limited to at least 508 MB and to
-at most 8GB. GRUB can't universally solve this problem, as there is no
-standard interface used in all machines. However, several newer machines
-have the new interface, Logical Block Address (@dfn{LBA}) mode. GRUB
-automatically detects if LBA mode is available and uses it if
-available. In LBA mode, GRUB can access the entire disk.
-
-@item Support network booting
-GRUB is basically a disk-based boot loader but also has network
-support. You can load OS images from a network by using the @dfn{TFTP}
-protocol.
-
-@item Support remote terminals
-To support computers with no console, GRUB provides remote terminal
-support, so that you can control GRUB from a remote host. Only serial
-terminal support is implemented at the moment.
-@end table

-
-@node Role of a boot loader
-@section The role of a boot loader
-
-The following is a quotation from Gordon Matzigkeit, a GRUB fanatic:
-
-@quotation
-Some people like to acknowledge both the operating system and kernel when
-they talk about their computers, so they might say they use
-``GNU/Linux'' or ``GNU/Hurd''. Other people seem to think that the
-kernel is the most important part of the system, so they like to call
-their GNU operating systems ``Linux systems.''
-
-I, personally, believe that this is a grave injustice, because the
-@emph{boot loader} is the most important software of all. I used to
-refer to the above systems as either ``LILO''@footnote{The LInux LOader,
-a boot loader that everybody uses, but nobody likes.} or ``GRUB''
-systems.
-
-Unfortunately, nobody ever understood what I was talking about; now I
-just use the word ``GNU'' as a pseudonym for GRUB.
-
-So, if you ever hear people talking about their alleged ``GNU'' systems,
-remember that they are actually paying homage to the best boot loader
-around@dots{} GRUB!
-@end quotation
-
-We, the GRUB maintainers, do not (usually) encourage Gordon's level of
-fanaticism, but it helps to remember that boot loaders deserve
-recognition. We hope that you enjoy using GNU GRUB as much as we did
-writing it.
-
-
-@node Naming convention
-@chapter Naming convention
-
-The device syntax used in GRUB is a wee bit different from what you may
-have seen before in your operating system(s), and you need to know it so
-that you can specify a drive/partition.
-
-Look at the following examples and explanations:
-
-@example
-(fd0)
-@end example
-
-First of all, GRUB requires that the device name be enclosed with
-@samp{(} and @samp{)}. The @samp{fd} part means that it is a floppy
-disk. The number @samp{0} is the drive number, which is counted from
-@emph{zero}. This expression means that GRUB will use the whole floppy
-disk.
-
-@example
-(hd0,1)
-@end example
-
-Here, @samp{hd} means it is a hard disk drive. The first integer
-@samp{0} indicates the drive number, that is, the first hard disk, while
-the second integer, @samp{1}, indicates the partition number (or the
-@sc{pc} slice number in the BSD terminology). Once again, please note
-that the partition numbers are counted from @emph{zero}, not from
-one. This expression means the second partition of the first hard disk
-drive. In this case, GRUB uses one partition of the disk, instead of the
-whole disk.
-
-@example
-(hd0,4)
-@end example
-
-This specifies the first @dfn{extended partition} of the first hard disk
-drive. Note that the partition numbers for extended partitions are
-counted from @samp{4}, regardless of the actual number of primary
-partitions on your hard disk.
-
-@example
-(hd1,a)
-@end example
-
-This means the BSD @samp{a} partition of the second hard disk. If you
-need to specify which @sc{pc} slice number should be used, use something
-like this: @samp{(hd1,0,a)}. If the @sc{pc} slice number is omitted,
-GRUB searches for the first @sc{pc} slice which has a BSD @samp{a}
-partition.
-
-Of course, to actually access the disks or partitions with GRUB, you
-need to use the device specification in a command, like @samp{root
-(fd0)} or @samp{unhide (hd0,2)}. To help you find out which number
-specifies a partition you want, the GRUB command-line
-(@pxref{Command-line interface}) options have argument
-completion. This means that, for example, you only need to type
-
-@example
-root (
-@end example
-
-followed by a @key{TAB}, and GRUB will display the list of drives,
-partitions, or file names. So it should be quite easy to determine the
-name of your target partition, even with minimal knowledge of the
-syntax.
-
-Note that GRUB does @emph{not} distinguish IDE from SCSI - it simply
-counts the drive numbers from zero, regardless of their type. Normally,
-any IDE drive number is less than any SCSI drive number, although that
-is not true if you change the boot sequence by swapping IDE and SCSI
-drives in your BIOS.
-
-Now the question is, how to specify a file? Again, consider an
-example:
-
-@example
-(hd0,0)/vmlinuz
-@end example
-
-This specifies the file named @samp{vmlinuz}, found on the first
-partition of the first hard disk drive. Note that the argument
-completion works with file names, too.
-
-That was easy, admit it. Now read the next chapter, to find out how to
-actually install GRUB on your drive.
-
-
-@node Installation
-@chapter Installation
-
-In order to install GRUB as your boot loader, you need to first
-install the GRUB system and utilities under your UNIX-like operating
-system (@pxref{Obtaining and Building GRUB}). You can do this either
-from the source tarball, or as a package for your OS.
-
-After you have done that, you need to install the boot loader on a
-drive (floppy or hard disk). There are two ways of doing that - either
-using the utility @command{grub-install} (@pxref{Invoking
-grub-install}) on a UNIX-like OS, or by running GRUB itself from a
-floppy. These are quite similar, however the utility might probe a
-wrong BIOS drive, so you should be careful.
-
-Also, if you install GRUB on a UNIX-like OS, please make sure that you
-have an emergency boot disk ready, so that you can rescue your computer
-if, by any chance, your hard drive becomes unusable (unbootable).
-
-GRUB comes with boot images, which are normally put in the directory
-@file{/usr/lib/grub/i386-pc}. If you do not use grub-install, then
-you need to copy the files @file{stage1}, @file{stage2}, and
-@file{*stage1_5} to the directory @file{/boot/grub}, and run the
-@command{grub-set-default} (@pxref{Invoking grub-set-default}) if you
-intend to use @samp{default saved} (@pxref{default}) in your
-configuration file. Hereafter, the directory where GRUB images are
-initially placed (normally @file{/usr/lib/grub/i386-pc}) will be
-called the @dfn{image directory}, and the directory where the boot
-loader needs to find them (usually @file{/boot/grub}) will be called
-the @dfn{boot directory}.

-@end menu
-
-
-@node Creating a GRUB boot floppy
-@section Creating a GRUB boot floppy
-
-To create a GRUB boot floppy, you need to take the files @file{stage1}
-and @file{stage2} from the image directory, and write them to the first
-and the second block of the floppy disk, respectively.
-
-@strong{Caution:} This procedure will destroy any data currently stored
-on the floppy.
-
-On a UNIX-like operating system, that is done with the following
-commands:
-
-@example
-@group
-# @kbd{cd /usr/lib/grub/i386-pc}
-# @kbd{dd if=stage1 of=/dev/fd0 bs=512 count=1}
-1+0 records in
-1+0 records out
-# @kbd{dd if=stage2 of=/dev/fd0 bs=512 seek=1}
-153+1 records in
-153+1 records out
-#
-@end group
-@end example
-
-The device file name may be different. Consult the manual for your OS.
-
-
-@node Installing GRUB natively
-@section Installing GRUB natively
-
-@strong{Caution:} Installing GRUB's stage1 in this manner will erase the
-normal boot sector used by an OS.
-
-GRUB can currently boot GNU Mach, Linux, FreeBSD, NetBSD, and OpenBSD
-directly, so using it on a boot sector (the first sector of a
-partition) should be okay. But generally, it would be a good idea to
-back up the first sector of the partition on which you are installing
-GRUB's stage1. This isn't as important if you are installing GRUB on
-the first sector of a hard disk, since it's easy to reinitialize it
-(e.g. by running @samp{FDISK /MBR} from DOS).
-
-If you decide to install GRUB in the native environment, which is
-definitely desirable, you'll need to create a GRUB boot disk, and
-reboot your computer with it. Otherwise, see @ref{Installing GRUB using
-grub-install}.
-
-Once started, GRUB will show the command-line interface
-(@pxref{Command-line interface}). First, set the GRUB's @dfn{root
-device}@footnote{Note that GRUB's root device doesn't necessarily mean
-your OS's root partition; if you need to specify a root partition for
-your OS, add the argument into the command @command{kernel}.} to the
-partition containing the boot directory, like this:
-
-@example
-grub> @kbd{root (hd0,0)}
-@end example
-
-If you are not sure which partition actually holds this directory, use the
-command @command{find} (@pxref{find}), like this:
-
-@example
-grub> @kbd{find /boot/grub/stage1}
-@end example
-
-This will search for the file name @file{/boot/grub/stage1} and show the
-devices which contain the file.
-
-Once you've set the root device correctly, run the command
-@command{setup} (@pxref{setup}):
-
-@example
-grub> @kbd{setup (hd0)}
-@end example
-
-This command will install the GRUB boot loader on the Master Boot
-Record (MBR) of the first drive. If you want to put GRUB into the boot
-sector of a partition instead of putting it in the MBR, specify the
-partition into which you want to install GRUB:
-
-@example
-grub> @kbd{setup (hd0,0)}
-@end example
-
-If you install GRUB into a partition or a drive other than the first
-one, you must chain-load GRUB from another boot loader. Refer to the
-manual for the boot loader to know how to chain-load GRUB.
-
-After using the setup command, you will boot into GRUB without the
-GRUB floppy. See the chapter @ref{Booting} to find out how to boot
-your operating systems from GRUB.
-
-
-@node Installing GRUB using grub-install
-@section Installing GRUB using grub-install
-
-@strong{Caution:} This procedure is definitely less safe, because
-there are several ways in which your computer can become
-unbootable. For example, most operating systems don't tell GRUB how to
-map BIOS drives to OS devices correctly---GRUB merely @dfn{guesses}
-the mapping. This will succeed in most cases, but not
-always. Therefore, GRUB provides you with a map file called the
-@dfn{device map}, which you must fix if it is wrong. @xref{Device
-map}, for more details.
-
-If you still do want to install GRUB under a UNIX-like OS (such
-as @sc{gnu}), invoke the program @command{grub-install} (@pxref{Invoking
-grub-install}) as the superuser (@dfn{root}).
-
-The usage is basically very simple. You only need to specify one
-argument to the program, namely, where to install the boot loader. The
-argument can be either a device file (like @samp{/dev/hda}) or a
-partition specified in GRUB's notation. For example, under Linux the
-following will install GRUB into the MBR of the first IDE disk:
-
-@example
-# @kbd{grub-install /dev/hda}
-@end example
-
-Likewise, under GNU/Hurd, this has the same effect:
-
-@example
-# @kbd{grub-install /dev/hd0}
-@end example
-
-If it is the first BIOS drive, this is the same as well:
-
-@example
-# @kbd{grub-install '(hd0)'}
-@end example
-
-Or you can omit the parentheses:
-
-@example
-# @kbd{grub-install hd0}
-@end example
-
-But all the above examples assume that GRUB should use images under
-the root directory. If you want GRUB to use images under a directory
-other than the root directory, you need to specify the option
-@option{--root-directory}. The typical usage is that you create a GRUB
-boot floppy with a filesystem. Here is an example:
-
-@example
-@group
-# @kbd{mke2fs /dev/fd0}
-# @kbd{mount -t ext2 /dev/fd0 /mnt}
-# @kbd{grub-install --root-directory=/mnt fd0}
-# @kbd{umount /mnt}
-@end group
-@end example
-
-Another example is when you have a separate boot partition
-which is mounted at @file{/boot}. Since GRUB is a boot loader, it
-doesn't know anything about mount points at all. Thus, you need to run
-@command{grub-install} like this:
-
-@example
-# @kbd{grub-install --root-directory=/boot /dev/hda}
-@end example
-
-By the way, as noted above, it is quite difficult to guess BIOS drives
-correctly under a UNIX-like OS. Thus, @command{grub-install} will prompt
-you to check if it could really guess the correct mappings, after the
-installation. The format is defined in @ref{Device map}. Please be
-quite careful. If the output is wrong, it is unlikely that your
-computer will be able to boot with no problem.
-
-Note that @command{grub-install} is actually just a shell script and the
-real task is done by the grub shell @command{grub} (@pxref{Invoking the
-grub shell}). Therefore, you may run @command{grub} directly to install
-GRUB, without using @command{grub-install}. Don't do that, however,
-unless you are very familiar with the internals of GRUB. Installing a
-boot loader on a running OS may be extremely dangerous.

-@node Making a GRUB bootable CD-ROM
-@section Making a GRUB bootable CD-ROM
-
-GRUB supports the @dfn{no emulation mode} in the El Torito
-specification@footnote{El Torito is a specification for bootable CD
-using BIOS functions.}. This means that you can use the whole CD-ROM
-from GRUB and you don't have to make a floppy or hard disk image file,
-which can cause compatibility problems.
-
-For booting from a CD-ROM, GRUB uses a special Stage 2 called
-@file{stage2_eltorito}. The only GRUB files you need to have in your
-bootable CD-ROM are this @file{stage2_eltorito} and optionally a config file
-@file{menu.lst}. You don't need to use @file{stage1} or @file{stage2},
-because El Torito is quite different from the standard boot process.
-
-Here is an example of procedures to make a bootable CD-ROM
-image. First, make a top directory for the bootable image, say,
-@samp{iso}:
-
-@example
-$ @kbd{mkdir iso}
-@end example
-
-Make a directory for GRUB:
-
-@example
-$ @kbd{mkdir -p iso/boot/grub}
-@end example
-
-Copy the file @file{stage2_eltorito}:
-
-@example
-$ @kbd{cp /usr/lib/grub/i386-pc/stage2_eltorito iso/boot/grub}
-@end example
-
-If desired, make the config file @file{menu.lst} under @file{iso/boot/grub}
-(@pxref{Configuration}), and copy any files and directories for the disc to the
-directory @file{iso/}.
-
-Finally, make a ISO9660 image file like this:
-
-@example
-$ @kbd{mkisofs -R -b boot/grub/stage2_eltorito -no-emul-boot \
- -boot-load-size 4 -boot-info-table -o grub.iso iso}
-@end example
-
-This produces a file named @file{grub.iso}, which then can be burned
-into a CD (or a DVD). @kbd{mkisofs} has already set up the disc to boot
-from the @kbd{boot/grub/stage2_eltorito} file, so there is no need to
-setup GRUB on the disc. (Note that the @kbd{-boot-load-size 4} bit is
-required for compatibility with the BIOS on many older machines.)
-
-You can use the device @samp{(cd)} to access a CD-ROM in your
-config file. This is not required; GRUB automatically sets the root device
-to @samp{(cd)} when booted from a CD-ROM. It is only necessary to refer to
-@samp{(cd)} if you want to access other drives as well.

-
-GRUB has two distinct boot methods. One of the two is to load an
-operating system directly, and the other is to chain-load another boot
-loader which then will load an operating system actually. Generally
-speaking, the former is more desirable, because you don't need to
-install or maintain other boot loaders and GRUB is flexible enough to
-load an operating system from an arbitrary disk/partition. However,
-the latter is sometimes required, since GRUB doesn't support all the
-existing operating systems natively.

-@node Loading an operating system directly
-@subsection How to boot an OS directly with GRUB
-
-Multiboot (@pxref{Top, Multiboot Specification, Motivation, multiboot,
-The Multiboot Specification}) is the native format supported by GRUB.
-For the sake of convenience, there is also support for Linux, FreeBSD,
-NetBSD and OpenBSD. If you want to boot other operating systems, you
-will have to chain-load them (@pxref{Chain-loading}).
-
-Generally, GRUB can boot any Multiboot-compliant OS in the following
-steps:
-
-@enumerate
-@item
-Set GRUB's root device to the drive where the OS images are stored with
-the command @command{root} (@pxref{root}).
-
-@item
-Load the kernel image with the command @command{kernel} (@pxref{kernel}).
-
-@item
-If you need modules, load them with the command @command{module}
-(@pxref{module}) or @command{modulenounzip} (@pxref{modulenounzip}).
-
-@item
-Run the command @command{boot} (@pxref{boot}).
-@end enumerate
-
-Linux, FreeBSD, NetBSD and OpenBSD can be booted in a similar
-manner. You load a kernel image with the command @command{kernel} and
-then run the command @command{boot}. If the kernel requires some
-parameters, just append the parameters to @command{kernel}, after the
-file name of the kernel. Also, please refer to @ref{OS-specific notes},
-for information on your OS-specific issues.

-If you want to boot an unsupported operating system (e.g. Windows 95),
-chain-load a boot loader for the operating system. Normally, the boot
-loader is embedded in the @dfn{boot sector} of the partition on which
-the operating system is installed.
-

-Load the kernel:
-
-@example
-grub> @kbd{kernel /vmlinuz root=/dev/hda1}

-If you need to specify some kernel parameters, just append them to the

-
-@example
-grub> @kbd{kernel /vmlinuz root=/dev/hda1 vga=ext}
-@end example
-
-See the documentation in the Linux source tree for complete

-
-GRUB can load the kernel directly, either in ELF or a.out format. But

-changes heavily, so GRUB can't guarantee to pass kernel parameters
-correctly.
-
-Thus, we'd recommend loading the very flexible loader
-@file{/boot/loader} instead. See this example:
-
-@example

-@enumerate
-@item
-Set GRUB's root device with @command{root} (@pxref{root}).
-
-@item
-Load the kernel with @command{kernel} (@pxref{kernel}). You should

-grub> @kbd{kernel --type=netbsd /netbsd-elf}
-@end example
-
-@item
-Run @command{boot} (@pxref{boot}).

-
-
-@node DOS/Windows
-@subsection DOS/Windows
-
-GRUB cannot boot DOS or Windows directly, so you must chain-load them
-(@pxref{Chain-loading}). However, their boot loaders have some critical
-deficiencies, so it may not work to just chain-load them. To overcome
-the problems, GRUB provides you with two helper functions.
-
-If you have installed DOS (or Windows) on a non-first hard disk, you
-have to use the disk swapping technique, because that OS cannot boot
-from any disks but the first one. The workaround used in GRUB is the
-command @command{map} (@pxref{map}), like this:
-
-@example
-@group
-grub> @kbd{map (hd0) (hd1)}
-grub> @kbd{map (hd1) (hd0)}
-@end group
-@end example
-
-This performs a @dfn{virtual} swap between your first and second hard
-drive.
-
-@strong{Caution:} This is effective only if DOS (or Windows) uses BIOS
-to access the swapped disks. If that OS uses a special driver for the
-disks, this probably won't work.
-
-Another problem arises if you installed more than one set of DOS/Windows
-onto one disk, because they could be confused if there are more than one
-primary partitions for DOS/Windows. Certainly you should avoid doing
-this, but there is a solution if you do want to do so. Use the partition
-hiding/unhiding technique.
-
-If GRUB @dfn{hide}s a DOS (or Windows) partition (@pxref{hide}), DOS (or
-Windows) will ignore the partition. If GRUB @dfn{unhide}s a DOS (or
-Windows) partition (@pxref{unhide}), DOS (or Windows) will detect the
-partition. Thus, if you have installed DOS (or Windows) on the first
-and the second partition of the first hard disk, and you want to boot
-the copy on the first partition, do the following:
-
-@example
-@group
-grub> @kbd{unhide (hd0,0)}
-grub> @kbd{hide (hd0,1)}
-grub> @kbd{rootnoverify (hd0,0)}

-@node Making your system robust
-@section How to make your system robust
-
-When you test a new kernel or a new OS, it is important to make sure
-that your computer can boot even if the new system is unbootable. This
-is crucial especially if you maintain servers or remote systems. To
-accomplish this goal, you need to set up two things:
-
-@enumerate
-@item
-You must maintain a system which is always bootable. For instance, if
-you test a new kernel, you need to keep a working kernel in a
-different place. And, it would sometimes be very nice to even have a
-complete copy of a working system in a different partition or disk.
-
-@item
-You must direct GRUB to boot a working system when the new system
-fails. This is possible with the @dfn{fallback} system in GRUB.
-@end enumerate
-
-The former requirement is very specific to each OS, so this
-documentation does not cover that topic. It is better to consult some
-backup tools.
-
-So let's see the GRUB part. There are two possibilities: one of them
-is quite simple but not very robust, and the other is a bit complex to
-set up but probably the best solution to make sure that your system
-can start as long as GRUB itself is bootable.
-
-@menu

-
-
-@node Booting once-only
-@subsection Booting once-only
-
-You can teach GRUB to boot an entry only at next boot time. Suppose
-that your have an old kernel @file{old_kernel} and a new kernel
-@file{new_kernel}. You know that @file{old_kernel} can boot
-your system correctly, and you want to test @file{new_kernel}.
-
-To ensure that your system will go back to the old kernel even if the
-new kernel fails (e.g. it panics), you can specify that GRUB should
-try the new kernel only once and boot the old kernel after that.
-
-First, modify your configuration file. Here is an example:
-
-@example
-@group
-default saved # This is important!!!
-timeout 10
-
-title the old kernel
-root (hd0,0)
-kernel /old_kernel
-savedefault
-
-title the new kernel
-root (hd0,0)
-kernel /new_kernel
-savedefault 0 # This is important!!!
-@end group
-@end example
-
-Note that this configuration file uses @samp{default saved}
-(@pxref{default}) at the head and @samp{savedefault 0}
-(@pxref{savedefault}) in the entry for the new kernel. This means
-that GRUB boots a saved entry by default, and booting the entry for the
-new kernel saves @samp{0} as the saved entry.
-
-With this configuration file, after all, GRUB always tries to boot the
-old kernel after it booted the new one, because @samp{0} is the entry
-of @code{the old kernel}.
-
-The next step is to tell GRUB to boot the new kernel at next boot
-time. For this, execute @command{grub-set-default} (@pxref{Invoking
-grub-set-default}):
-
-@example
-# @kbd{grub-set-default 1}
-@end example
-
-This command sets the saved entry to @samp{1}, that is, to the new
-kernel.
-
-This method is useful, but still not very robust, because GRUB stops
-booting, if there is any error in the boot entry, such that the new
-kernel has an invalid executable format. Thus, it it even better to
-use the @dfn{fallback} mechanism of GRUB. Look at next subsection for
-this feature.
-
-
-@node Booting fallback systems
-@subsection Booting fallback systems
-
-GRUB supports a fallback mechanism of booting one or more other
-entries if a default boot entry fails. You can specify multiple
-fallback entries if you wish.
-
-Suppose that you have three systems, @samp{A}, @samp{B} and
-@samp{C}. @samp{A} is a system which you want to boot by
-default. @samp{B} is a backup system which is supposed to boot
-safely. @samp{C} is another backup system which is used in case where
-@samp{B} is broken.
-
-Then you may want GRUB to boot the first system which is bootable
-among @samp{A}, @samp{B} and @samp{C}. A configuration file can be
-written in this way:
-
-@example
-@group
-default saved # This is important!!!
-timeout 10
-fallback 1 2 # This is important!!!
-
-title A
-root (hd0,0)
-kernel /kernel
-savedefault fallback # This is important!!!
-
-title B
-root (hd1,0)
-kernel /kernel
-savedefault fallback # This is important!!!
-
-title C
-root (hd2,0)
-kernel /kernel
-savedefault
-@end group
-@end example
-
-Note that @samp{default saved} (@pxref{default}), @samp{fallback 1 2}
-and @samp{savedefault fallback} are used. GRUB will boot a saved entry
-by default and save a fallback entry as next boot entry with this
-configuration.
-
-When GRUB tries to boot @samp{A}, GRUB saves @samp{1} as next boot
-entry, because the command @command{fallback} specifies that @samp{1}
-is the first fallback entry. The entry @samp{1} is @samp{B}, so GRUB
-will try to boot @samp{B} at next boot time.
-
-Likewise, when GRUB tries to boot @samp{B}, GRUB saves @samp{2} as
-next boot entry, because @command{fallback} specifies @samp{2} as next
-fallback entry. This makes sure that GRUB will boot @samp{C} after
-booting @samp{B}.
-
-It is noteworthy that GRUB uses fallback entries both when GRUB
-itself fails in booting an entry and when @samp{A} or @samp{B} fails
-in starting up your system. So this solution ensures that your system
-is started even if GRUB cannot find your kernel or if your kernel
-panics.
-
-However, you need to run @command{grub-set-default} (@pxref{Invoking
-grub-set-default}) when @samp{A} starts correctly or you fix @samp{A}
-after it crashes, since GRUB always sets next boot entry to a fallback
-entry. You should run this command in a startup script such as
-@file{rc.local} to boot @samp{A} by default:
-
-@example
-# @kbd{grub-set-default 0}
-@end example
-
-where @samp{0} is the number of the boot entry for the system
-@samp{A}.
-
-If you want to see what is current default entry, you can look at the
-file @file{/boot/grub/default} (or @file{/grub/default} in
-some systems). Because this file is plain-text, you can just
-@command{cat} this file. But it is strongly recommended @strong{not to
-modify this file directly}, because GRUB may fail in saving a default
-entry in this file, if you change this file in an unintended
-manner. Therefore, you should use @command{grub-set-default} when you
-need to change the default entry.
-
-
-@node Configuration
-@chapter Configuration
-
-You've probably noticed that you need to type several commands to boot your
-OS. There's a solution to that - GRUB provides a menu interface
-(@pxref{Menu interface}) from which you can select an item (using arrow
-keys) that will do everything to boot an OS.
-
-To enable the menu, you need a configuration file,
-@file{menu.lst} under the boot directory. We'll analyze an example
-file.
-
-The file first contains some general settings, the menu interface
-related options. You can put these commands (@pxref{Menu-specific
-commands}) before any of the items (starting with @command{title}
-(@pxref{title})).
-
-@example
-@group
-#
-# Sample boot menu configuration file
-#
-@end group
-@end example
-
-As you may have guessed, these lines are comments. Lines starting with a
-hash character (@samp{#}), and blank lines, are ignored by GRUB.
-
-@example
-@group
-# By default, boot the first entry.
-default 0
-@end group
-@end example
-
-The first entry (here, counting starts with number zero, not one!) will
-be the default choice.
-
-@example
-@group
-# Boot automatically after 30 secs.
-timeout 30
-@end group
-@end example
-
-As the comment says, GRUB will boot automatically in 30 seconds, unless
-interrupted with a key press.
-
-@example
-@group
-# Fallback to the second entry.
-fallback 1
-@end group
-@end example
-
-If, for any reason, the default entry doesn't work, fall back to the
-second one (this is rarely used, for obvious reasons).
-
-Note that the complete descriptions of these commands, which are menu
-interface specific, can be found in @ref{Menu-specific
-commands}. Other descriptions can be found in @ref{Commands}.
-
-Now, on to the actual OS definitions. You will see that each entry
-begins with a special command, @command{title} (@pxref{title}), and the
-action is described after it. Note that there is no command
-@command{boot} (@pxref{boot}) at the end of each item. That is because
-GRUB automatically executes @command{boot} if it loads other commands
-successfully.
-
-The argument for the command @command{title} is used to display a short
-title/description of the entry in the menu. Since @command{title}
-displays the argument as is, you can write basically anything there.
-
-@example
-@group
-# For booting GNU/Hurd
-title GNU/Hurd
-root (hd0,0)
-kernel /boot/gnumach.gz root=hd0s1
-module /boot/serverboot.gz
-@end group
-@end example
-
-This boots GNU/Hurd from the first hard disk.
-
-@example
-@group
-# For booting GNU/Linux
-title GNU/Linux
-kernel (hd1,0)/vmlinuz root=/dev/hdb1
-@end group
-@end example
-
-This boots GNU/Linux, but from the second hard disk.
-
-@example
-@group
-# For booting Mach (getting kernel from floppy)
-title Utah Mach4 multiboot
-root (hd0,2)
-pause Insert the diskette now^G!!
-kernel (fd0)/boot/kernel root=hd0s3
-module (fd0)/boot/bootstrap
-@end group
-@end example
-
-This boots Mach with a kernel on a floppy, but the root filesystem at
-hd0s3. It also contains a @command{pause} line (@pxref{pause}), which
-will cause GRUB to display a prompt and delay, before actually executing
-the rest of the commands and booting.
-
-@example
-@group
-# For booting FreeBSD
-title FreeBSD
-root (hd0,2,a)
-kernel /boot/loader
-@end group
-@end example
-
-This item will boot FreeBSD kernel loaded from the @samp{a} partition of
-the third @sc{pc} slice of the first hard disk.
-
-@example
-@group
-# For booting OS/2

-This will just (re)install GRUB onto the hard disk.
-
-@example
-# Change the colors.
-title Change the colors

-@end example
-
-In the last entry, the command @command{color} is used (@pxref{color}),
-to change the menu colors (try it!). This command is somewhat special,
-because it can be used both in the command-line and in the menu. GRUB
-has several such commands, see @ref{General commands}.
-
-We hope that you now understand how to use the basic features of
-GRUB. To learn more about GRUB, see the following chapters.
-
-
-@node Network
-@chapter Downloading OS images from a network
-
-Although GRUB is a disk-based boot loader, it does provide network
-support. To use the network support, you need to enable at least one
-network driver in the GRUB build process. For more information please
-see @file{netboot/README.netboot} in the source distribution.

-
-@node General usage of network support
-@section How to set up your network
-
-GRUB requires a file server and optionally a server that will assign an
-IP address to the machine on which GRUB is running. For the former, only
-TFTP is supported at the moment. The latter is either BOOTP, DHCP or a
-RARP server@footnote{RARP is not advised, since it cannot serve much
-information}. It is not necessary to run both the servers on one
-computer. How to configure these servers is beyond the scope of this
-document, so please refer to the manuals specific to those
-protocols/servers.
-
-If you decided to use a server to assign an IP address, set up the
-server and run @command{bootp} (@pxref{bootp}), @command{dhcp}
-(@pxref{dhcp}) or @command{rarp} (@pxref{rarp}) for BOOTP, DHCP or RARP,
-respectively. Each command will show an assigned IP address, a netmask,
-an IP address for your TFTP server and a gateway. If any of the
-addresses is wrong or it causes an error, probably the configuration of
-your servers isn't set up properly.
-
-Otherwise, run @command{ifconfig}, like this:
-
-@example
-grub> @kbd{ifconfig --address=192.168.110.23 --server=192.168.110.14}
-@end example
-
-You can also use @command{ifconfig} in conjunction with @command{bootp},
-@command{dhcp} or @command{rarp} (e.g. to reassign the server address
-manually). @xref{ifconfig}, for more details.
-
-Finally, download your OS images from your network. The network can be
-accessed using the network drive @samp{(nd)}. Everything else is very
-similar to the normal instructions (@pxref{Booting}).
-
-Here is an example:
-
-@example
-@group
-grub> @kbd{bootp}
-Probing... [NE*000]
-NE2000 base ...
-Address: 192.168.110.23 Netmask: 255.255.255.0
-Server: 192.168.110.14 Gateway: 192.168.110.1
-
-grub> @kbd{root (nd)}
-grub> @kbd{kernel /tftproot/gnumach.gz root=sd0s1}
-grub> @kbd{module /tftproot/serverboot.gz}
-grub> @kbd{boot}
-@end group
-@end example
-
-
-@node Diskless
-@section Booting from a network
-
-It is sometimes very useful to boot from a network, especially when you
-use a machine which has no local disk. In this case, you need to obtain
-a kind of Net Boot @sc{rom}, such as a PXE @sc{rom} or a free software
-package like Etherboot. Such a Boot @sc{rom} first boots the machine,
-sets up the network card installed into the machine, and downloads a
-second stage boot image from the network. Then, the second image will
-try to boot an operating system actually from the network.
-
-GRUB provides two second stage images, @file{nbgrub} and
-@file{pxegrub} (@pxref{Images}). These images are the same as the
-normal Stage 2, except that they set up a network automatically, and try
-to load a configuration file from the network, if specified. The usage
-is very simple: If the machine has a PXE @sc{rom}, use
-@file{pxegrub}. If the machine has an NBI loader such as Etherboot, use
-@file{nbgrub}. There is no difference between them except their
-formats. Since the way to load a second stage image you want to use
-should be described in the manual on your Net Boot @sc{rom}, please
-refer to the manual, for more information.
-
-However, there is one thing specific to GRUB. Namely, how to specify a
-configuration file in a BOOTP/DHCP server. For now, GRUB uses the tag
-@samp{150}, to get the name of a configuration file. The following is an
-example with a BOOTP configuration:
-
-@example
-@group
-.allhost:hd=/tmp:bf=null:\
- :ds=145.71.35.1 145.71.32.1:\
- :sm=255.255.254.0:\
- :gw=145.71.35.1:\
- :sa=145.71.35.5:
-
-foo:ht=1:ha=63655d0334a7:ip=145.71.35.127:\
- :bf=/nbgrub:\
- :tc=.allhost:\
- :T150="(nd)/tftpboot/menu.lst.foo":
-@end group
-@end example
-
-Note that you should specify the drive name @code{(nd)} in the name of
-the configuration file. This is because you might change the root drive
-before downloading the configuration from the TFTP server when the
-preset menu feature is used (@pxref{Preset Menu}).
-
-See the manual of your BOOTP/DHCP server for more information. The
-exact syntax should differ a little from the example.
-
-
-@node Serial terminal
-@chapter Using GRUB via a serial line
-
-This chapter describes how to use the serial terminal support in GRUB.
-
-If you have many computers or computers with no display/keyboard, it
-could be very useful to control the computers through serial
-communications. To connect one computer with another via a serial line,
-you need to prepare a null-modem (cross) serial cable, and you may need
-to have multiport serial boards, if your computer doesn't have extra
-serial ports. In addition, a terminal emulator is also required, such as
-minicom. Refer to a manual of your operating system, for more
-information.
-
-As for GRUB, the instruction to set up a serial terminal is quite
-simple. First of all, make sure that you haven't specified the option
-@option{--disable-serial} to the configure script when you built your
-GRUB images. If you get them in binary form, probably they have serial
-terminal support already.
-
-Then, initialize your serial terminal after GRUB starts up. Here is an
-example:
-
-@example
-@group
-grub> @kbd{serial --unit=0 --speed=9600}
-grub> @kbd{terminal serial}
-@end group
-@end example
-
-The command @command{serial} initializes the serial unit 0 with the
-speed 9600bps. The serial unit 0 is usually called @samp{COM1}, so, if
-you want to use COM2, you must specify @samp{--unit=1} instead. This
-command accepts many other options, so please refer to @ref{serial},
-for more details.
-
-The command @command{terminal} (@pxref{terminal}) chooses which type of
-terminal you want to use. In the case above, the terminal will be a
-serial terminal, but you can also pass @code{console} to the command,
-as @samp{terminal serial console}. In this case, a terminal in which
-you press any key will be selected as a GRUB terminal.
-
-However, note that GRUB assumes that your terminal emulator is
-compatible with VT100 by default. This is true for most terminal
-emulators nowadays, but you should pass the option @option{--dumb} to
-the command if your terminal emulator is not VT100-compatible or
-implements few VT100 escape sequences. If you specify this option then
-GRUB provides you with an alternative menu interface, because the normal
-menu requires several fancy features of your terminal.
-
-
-@node Preset Menu
-@chapter Embedding a configuration file into GRUB
-
-GRUB supports a @dfn{preset menu} which is to be always loaded before
-starting. The preset menu feature is useful, for example, when your
-computer has no console but a serial cable. In this case, it is
-critical to set up the serial terminal as soon as possible, since you
-cannot see any message until the serial terminal begins to work. So it
-is good to run the commands @command{serial} (@pxref{serial}) and
-@command{terminal} (@pxref{terminal}) before anything else at the
-start-up time.
-
-How the preset menu works is slightly complicated:
-
-@enumerate
-@item
-GRUB checks if the preset menu feature is used, and loads the preset
-menu, if available. This includes running commands and reading boot
-entries, like an ordinary configuration file.
-
-@item
-GRUB checks if the configuration file is available. Note that this check
-is performed @strong{regardless of the existence of the preset
-menu}. The configuration file is loaded even if the preset menu was
-loaded.
-
-@item
-If the preset menu includes any boot entries, they are cleared when
-the configuration file is loaded. It doesn't matter whether the
-configuration file has any entries or no entry. The boot entries in the
-preset menu are used only when GRUB fails in loading the configuration
-file.
-@end enumerate
-
-To enable the preset menu feature, you must rebuild GRUB specifying a
-file to the configure script with the option
-@option{--enable-preset-menu}. The file has the same semantics as
-normal configuration files (@pxref{Configuration}).
-
-Another point you should take care is that the diskless support
-(@pxref{Diskless}) diverts the preset menu. Diskless images embed a
-preset menu to execute the command @command{bootp} (@pxref{bootp})
-automatically, unless you specify your own preset menu to the configure
-script. This means that you must put commands to initialize a network in
-the preset menu yourself, because diskless images don't set it up
-implicitly, when you use the preset menu explicitly.
-
-Therefore, a typical preset menu used with diskless support would be
-like this:
-
-@example
-@group
-# Set up the serial terminal, first of all.
-serial --unit=0 --speed=19200
-terminal --timeout=0 serial
-
-# Initialize the network.
-dhcp
-@end group
-@end example
-
-
-@node Security
-@chapter Protecting your computer from cracking
-
-You may be interested in how to prevent ordinary users from doing
-whatever they like, if you share your computer with other people. So
-this chapter describes how to improve the security of GRUB.
-
-One thing which could be a security hole is that the user can do too
-many things with GRUB, because GRUB allows one to modify its configuration
-and run arbitrary commands at run-time. For example, the user can even
-read @file{/etc/passwd} in the command-line interface by the command
-@command{cat} (@pxref{cat}). So it is necessary to disable all the
-interactive operations.
-
-Thus, GRUB provides a @dfn{password} feature, so that only administrators
-can start the interactive operations (i.e. editing menu entries and
-entering the command-line interface). To use this feature, you need to
-run the command @command{password} in your configuration file
-(@pxref{password}), like this:
-
-@example
-password --md5 PASSWORD
-@end example
-
-If this is specified, GRUB disallows any interactive control, until you
-press the key @key{p} and enter a correct password. The option
-@option{--md5} tells GRUB that @samp{PASSWORD} is in MD5 format. If it
-is omitted, GRUB assumes the @samp{PASSWORD} is in clear text.
-
-You can encrypt your password with the command @command{md5crypt}
-(@pxref{md5crypt}). For example, run the grub shell (@pxref{Invoking the
-grub shell}), and enter your password:
-
-@example
-@group
-grub> md5crypt
-Password: **********
-Encrypted: $1$U$JK7xFegdxWH6VuppCUSIb.
-@end group
-@end example
-
-Then, cut and paste the encrypted password to your configuration file.
-
-Also, you can specify an optional argument to @command{password}. See
-this example:
-
-@example
-password PASSWORD /boot/grub/menu-admin.lst
-@end example
-
-In this case, GRUB will load @file{/boot/grub/menu-admin.lst} as a
-configuration file when you enter the valid password.
-
-Another thing which may be dangerous is that any user can choose any
-menu entry. Usually, this wouldn't be problematic, but you might want to
-permit only administrators to run some of your menu entries, such as an
-entry for booting an insecure OS like DOS.
-
-GRUB provides the command @command{lock} (@pxref{lock}). This command
-always fails until you enter the valid password, so you can use it, like
-this:
-
-@example
-@group
-title Boot DOS
-lock
-rootnoverify (hd0,1)
-makeactive
-chainload +1
-@end group
-@end example
-
-You should insert @command{lock} right after @command{title}, because
-any user can execute commands in an entry until GRUB encounters
-@command{lock}.
-
-You can also use the command @command{password} instead of
-@command{lock}. In this case the boot process will ask for the password
-and stop if it was entered incorrectly. Since the @command{password}
-takes its own @var{PASSWORD} argument this is useful if you want
-different passwords for different entries.
-
-
-@node Images
-@chapter GRUB image files
-
-GRUB consists of several images: two essential stages, optional stages
-called @dfn{Stage 1.5}, one image for bootable CD-ROM, and two network
-boot images. Here is a short overview of them. @xref{Internals}, for
-more details.
-
-@table @file
-@item stage1
-This is an essential image used for booting up GRUB. Usually, this is
-embedded in an MBR or the boot sector of a partition. Because a PC boot
-sector is 512 bytes, the size of this image is exactly 512 bytes.
-
-All @file{stage1} must do is to load Stage 2 or Stage 1.5 from a local
-disk. Because of the size restriction, @file{stage1} encodes the
-location of Stage 2 (or Stage 1.5) in a blocklist format, so it never
-understand any filesystem structure.
-
-@item stage2
-This is the core image of GRUB. It does everything but booting up
-itself. Usually, this is put in a filesystem, but that is not required.
-
-@item e2fs_stage1_5
-@itemx fat_stage1_5
-@itemx ffs_stage1_5
-@itemx jfs_stage1_5
-@itemx minix_stage1_5
-@itemx reiserfs_stage1_5
-@itemx vstafs_stage1_5
-@itemx xfs_stage1_5
-
-These are called @dfn{Stage 1.5}, because they serve as a bridge
-between @file{stage1} and @file{stage2}, that is to say, Stage 1.5 is
-loaded by Stage 1 and Stage 1.5 loads Stage 2. The difference between
-@file{stage1} and @file{*_stage1_5} is that the former doesn't
-understand any filesystem while the latter understands one filesystem
-(e.g. @file{e2fs_stage1_5} understands ext2fs). So you can move the
-Stage 2 image to another location safely, even after GRUB has been
-installed.
-
-While Stage 2 cannot generally be embedded in a fixed area as the size
-is so large, Stage 1.5 can be installed into the area right after an MBR,
-or the boot loader area of a ReiserFS or a FFS.
-
-@item stage2_eltorito
-This is a boot image for CD-ROMs using the @dfn{no emulation mode} in
-El Torito specification. This is identical to Stage 2, except that
-this boots up without Stage 1 and sets up a special drive @samp{(cd)}.
-
-@item nbgrub
-This is a network boot image for the Network Image Proposal used by some
-network boot loaders, such as Etherboot. This is mostly the same as
-Stage 2, but it also sets up a network and loads a configuration file
-from the network.
-
-@item pxegrub
-This is another network boot image for the Preboot Execution Environment
-used by several Netboot ROMs. This is identical to @file{nbgrub}, except
-for the format.
-@end table
-
-
-@node Filesystem
-@chapter Filesystem syntax and semantics
-
-GRUB uses a special syntax for specifying disk drives which can be
-accessed by BIOS. Because of BIOS limitations, GRUB cannot distinguish
-between IDE, ESDI, SCSI, or others. You must know yourself which BIOS
-device is equivalent to which OS device. Normally, that will be clear if
-you see the files in a device or use the command @command{find}
-(@pxref{find}).
-
-@menu
-* Device syntax:: How to specify devices
-* File name syntax:: How to specify files
-* blocklist syntax:: How to specify blocklists
-@end menu
-
-
-@node Device syntax
-@section How to specify devices
-
-The device syntax is like this:
-
-@example
-@code{(@var{device}[,@var{part-num}][,@var{bsd-subpart-letter}])}
-@end example
-
-@samp{[]} means the parameter is optional. @var{device} should be
-either @samp{fd} or @samp{hd} followed by a digit, like @samp{fd0}.
-But you can also set @var{device} to a hexadecimal or a decimal number
-which is a BIOS drive number, so the following are equivalent:
-
-@example
-(hd0)
-(0x80)
-(128)
-@end example
-
-@var{part-num} represents the partition number of @var{device}, starting
-from zero for primary partitions and from four for extended partitions,
-and @var{bsd-subpart-letter} represents the BSD disklabel subpartition,
-such as @samp{a} or @samp{e}.
-
-A shortcut for specifying BSD subpartitions is
-@code{(@var{device},@var{bsd-subpart-letter})}, in this case, GRUB
-searches for the first PC partition containing a BSD disklabel, then
-finds the subpartition @var{bsd-subpart-letter}. Here is an example:
-
-@example
-(hd0,a)
-@end example
-
-The syntax @samp{(hd0)} represents using the entire disk (or the
-MBR when installing GRUB), while the syntax @samp{(hd0,0)}
-represents using the first partition of the disk (or the boot sector
-of the partition when installing GRUB).
-
-If you enabled the network support, the special drive, @samp{(nd)}, is
-also available. Before using the network drive, you must initialize the
-network. @xref{Network}, for more information.
-
-If you boot GRUB from a CD-ROM, @samp{(cd)} is available. @xref{Making
-a GRUB bootable CD-ROM}, for details.
-
-
-@node File name syntax
-@section How to specify files
-
-There are two ways to specify files, by @dfn{absolute file name} and by
-@dfn{blocklist}.
-
-An absolute file name resembles a Unix absolute file name, using
-@samp{/} for the directory separator (not @samp{\} as in DOS). One
-example is @samp{(hd0,0)/boot/grub/menu.lst}. This means the file
-@file{/boot/grub/menu.lst} in the first partition of the first hard
-disk. If you omit the device name in an absolute file name, GRUB uses
-GRUB's @dfn{root device} implicitly. So if you set the root device to,
-say, @samp{(hd1,0)} by the command @command{root} (@pxref{root}), then
-@code{/boot/kernel} is the same as @code{(hd1,0)/boot/kernel}.
-
-
-@node blocklist syntax
-@section How to specify blocklists
-
-A blocklist is used for specifying a file that doesn't appear in the
-filesystem, like a chainloader. The syntax is
-@code{[@var{offset}]+@var{length}[,[@var{offset}]+@var{length}]@dots{}}.
-Here is an example:
-
-@example
-@code{0+100,200+1,300+300}
-@end example
-
-This represents that GRUB should read blocks 0 through 99, block 200,
-and blocks 300 through 599. If you omit an offset, then GRUB assumes
-the offset is zero.
-
-Like the file name syntax (@pxref{File name syntax}), if a blocklist
-does not contain a device name, then GRUB uses GRUB's @dfn{root
-device}. So @code{(hd0,1)+1} is the same as @code{+1} when the root
-device is @samp{(hd0,1)}.
-
-
-@node Interface
-@chapter GRUB's user interface
-
-GRUB has both a simple menu interface for choosing preset entries from a
-configuration file, and a highly flexible command-line for performing
-any desired combination of boot commands.
-
-GRUB looks for its configuration file as soon as it is loaded. If one
-is found, then the full menu interface is activated using whatever
-entries were found in the file. If you choose the @dfn{command-line} menu
-option, or if the configuration file was not found, then GRUB drops to
-the command-line interface.
-
-@menu
-* Command-line interface:: The flexible command-line interface
-* Menu interface:: The simple menu interface
-* Menu entry editor:: Editing a menu entry
-* Hidden menu interface:: The hidden menu interface
-@end menu
-
-
-@node Command-line interface
-@section The flexible command-line interface
-
-The command-line interface provides a prompt and after it an editable
-text area much like a command-line in Unix or DOS. Each command is
-immediately executed after it is entered@footnote{However, this
-behavior will be changed in the future version, in a user-invisible
-way.}. The commands (@pxref{Command-line and menu entry commands}) are a
-subset of those available in the configuration file, used with exactly
-the same syntax.
-
-Cursor movement and editing of the text on the line can be done via a
-subset of the functions available in the Bash shell:
-
-@table @key
-@item C-f
-@itemx PC right key
-Move forward one character.
-
-@item C-b
-@itemx PC left key
-Move back one character.
-
-@item C-a
-@itemx HOME
-Move to the start of the line.
-
-@item C-e
-@itemx END
-Move the the end of the line.
-
-@item C-d
-@itemx DEL
-Delete the character underneath the cursor.
-
-@item C-h
-@itemx BS
-Delete the character to the left of the cursor.
-
-@item C-k
-Kill the text from the current cursor position to the end of the line.
-
-@item C-u
-Kill backward from the cursor to the beginning of the line.
-
-@item C-y
-Yank the killed text back into the buffer at the cursor.
-
-@item C-p
-@itemx PC up key
-Move up through the history list.
-
-@item C-n
-@itemx PC down key
-Move down through the history list.
-@end table
-
-When typing commands interactively, if the cursor is within or before
-the first word in the command-line, pressing the @key{TAB} key (or
-@key{C-i}) will display a listing of the available commands, and if the
-cursor is after the first word, the @kbd{@key{TAB}} will provide a
-completion listing of disks, partitions, and file names depending on the
-context. Note that to obtain a list of drives, one must open a
-parenthesis, as @command{root (}.
-
-Note that you cannot use the completion functionality in the TFTP
-filesystem. This is because TFTP doesn't support file name listing for
-the security.
-
-
-@node Menu interface
-@section The simple menu interface
-
-The menu interface is quite easy to use. Its commands are both
-reasonably intuitive and described on screen.
-
-Basically, the menu interface provides a list of @dfn{boot entries} to
-the user to choose from. Use the arrow keys to select the entry of
-choice, then press @key{RET} to run it. An optional timeout is
-available to boot the default entry (the first one if not set), which is
-aborted by pressing any key.
-
-Commands are available to enter a bare command-line by pressing @key{c}
-(which operates exactly like the non-config-file version of GRUB, but
-allows one to return to the menu if desired by pressing @key{ESC}) or to
-edit any of the @dfn{boot entries} by pressing @key{e}.
-
-If you protect the menu interface with a password (@pxref{Security}),
-all you can do is choose an entry by pressing @key{RET}, or press
-@key{p} to enter the password.
-
-
-@node Menu entry editor
-@section Editing a menu entry
-
-The menu entry editor looks much like the main menu interface, but the
-lines in the menu are individual commands in the selected entry instead
-of entry names.
-
-If an @key{ESC} is pressed in the editor, it aborts all the changes made
-to the configuration entry and returns to the main menu interface.
-
-When a particular line is selected, the editor places the user in a
-special version of the GRUB command-line to edit that line. When the
-user hits @key{RET}, GRUB replaces the line in question in the boot
-entry with the changes (unless it was aborted via @key{ESC},
-in which case the changes are thrown away).
-
-If you want to add a new line to the menu entry, press @key{o} if adding
-a line after the current line or press @key{O} if before the current
-line.
-
-To delete a line, hit the key @key{d}. Although GRUB unfortunately
-does not support @dfn{undo}, you can do almost the same thing by just
-returning to the main menu.
-
-
-@node Hidden menu interface
-@section The hidden menu interface
-
-When your terminal is dumb or you request GRUB to hide the menu
-interface explicitly with the command @command{hiddenmenu}
-(@pxref{hiddenmenu}), GRUB doesn't show the menu interface (@pxref{Menu
-interface}) and automatically boots the default entry, unless
-interrupted by pressing @key{ESC}.
-
-When you interrupt the timeout and your terminal is dumb, GRUB falls
-back to the command-line interface (@pxref{Command-line interface}).
-
-
-@node Commands
-@chapter The list of available commands
-
-In this chapter, we list all commands that are available in GRUB.
-
-Commands belong to different groups. A few can only be used in
-the global section of the configuration file (or ``menu''); most
-of them can be entered on the command-line and can be used either
-anywhere in the menu or specifically in the menu entries.

-Initialize a serial device. @var{unit} is a number in the range 0-3
-specifying which serial port to use; default is 0, which corresponds to
-the port often called COM1. @var{port} is the I/O port where the UART
-is to be found; if specified it takes precedence over @var{unit}.
-@var{speed} is the transmission speed; default is 9600. @var{word} and
-@var{stop} are the number of data bits and stop bits. Data bits must
-be in the range 5-8 and stop bits must be 1 or 2. Default is 8 data
-bits and one stop bit. @var{parity} is one of @samp{no}, @samp{odd},
-@samp{even} and defaults to @samp{no}. The option @option{--device}
-can only be used in the grub shell and is used to specify the
-tty device to be used in the host operating system (@pxref{Invoking the

-Select a terminal for user interaction. The terminal is assumed to be
-VT100-compatible unless @option{--dumb} is specified. If both
-@option{console} and @option{serial} are specified, then GRUB will use
-the one where a key is entered first or the first when the timeout

-
-This may not make sense for most users, but GRUB supports Hercules
-console as well. Hercules console is usable like the ordinary console,
-and the usage is quite similar to that for serial terminals: specify
-@option{hercules} as the argument.
-
-The option @option{--lines} defines the number of lines in your

-@deffn Command install [@option{--force-lba}] [@option{--stage2=os_stage2_file}] stage1_file [@option{d}] dest_dev stage2_file [addr] [@option{p}] [config_file] [real_config_file]
-This command is fairly complex, and you should not use this command
-unless you are familiar with GRUB. Use @command{setup} (@pxref{setup})
-instead.
-
-In short, it will perform a full install presuming the Stage 2 or Stage
-1.5@footnote{They're loaded the same way, so we will refer to the Stage
-1.5 as a Stage 2 from now on.} is in its final install location.
-
-In slightly more detail, it will load @var{stage1_file}, validate that
-it is a GRUB Stage 1 of the right version number, install in it a
-blocklist for loading @var{stage2_file} as a Stage 2. If the option
-@option{d} is present, the Stage 1 will always look for the actual
-disk @var{stage2_file} was installed on, rather than using the booting
-drive. The Stage 2 will be loaded at address @var{addr}, which must be
-@samp{0x8000} for a true Stage 2, and @samp{0x2000} for a Stage 1.5. If
-@var{addr} is not present, GRUB will determine the address
-automatically. It then writes the completed Stage 1 to the first block
-of the device @var{dest_dev}. If the options @option{p} or
-@var{config_file} are present, then it reads the first block of stage2,
-modifies it with the values of the partition @var{stage2_file} was found
-on (for @option{p}) or places the string @var{config_file} into the area
-telling the stage2 where to look for a configuration file at boot
-time. Likewise, if @var{real_config_file} is present and
-@var{stage2_file} is a Stage 1.5, then the Stage 2 @var{config_file} is
-patched with the configuration file name @var{real_config_file}. This
-command preserves the DOS BPB (and for hard disks, the partition table)
-of the sector the Stage 1 is to be installed into.
-
-@strong{Caution:} Several buggy BIOSes don't pass a booting drive
-properly when booting from a hard disk drive. Therefore, you will
-unfortunately have to specify the option @option{d}, whether your
-Stage2 resides at the booting drive or not, if you have such a
-BIOS. We know these are defective in this way:
-
-@table @asis
-@item
-Fujitsu LifeBook 400 BIOS version 31J0103A
-
-@item
-HP Vectra XU 6/200 BIOS version GG.06.11
-@end table
-
-@strong{Caution2:} A number of BIOSes don't return a correct LBA support
-bitmap even if they do have the support. So GRUB provides a solution to
-ignore the wrong bitmap, that is, the option @option{--force-lba}. Don't
-use this option if you know that your BIOS doesn't have LBA support.
-
-@strong{Caution3:} You must specify the option @option{--stage2} in the
-grub shell, if you cannot unmount the filesystem where your stage2 file
-resides. The argument should be the file name in your operating system.

-@var{file}. The rest of the line is passed verbatim as the @dfn{kernel
-command-line}. Any modules must be reloaded after using this command.
-
-This command also accepts the option @option{--type} so that you can
-specify the kernel type of @var{file} explicitly. The argument
-@var{type} must be one of these: @samp{netbsd}, @samp{freebsd},
-@samp{openbsd}, @samp{linux}, @samp{biglinux}, and
-@samp{multiboot}. However, you need to specify it only if you want to
-load a NetBSD @sc{elf} kernel, because GRUB can automatically determine
-a kernel type in the other cases, quite safely.
-
-The option @option{--no-mem-option} is effective only for Linux. If the

-A disk read error happened while trying to read the stage2 or stage1.5.
-
-@item Geom Error
-The location of the stage2 or stage1.5 is not in the portion of the disk

-BIOS translated geometry has been changed by the user or the disk is
-moved to another machine or controller after installation, or GRUB was

-
-The general way that the Stage 2 handles errors is to abort the

-continue based on the fact that an error occurred or wait for the user to
-deal with the error.
-
-The following is a comprehensive list of error messages for the Stage 2
-(error numbers for the Stage 1.5 are listed before the colon in each
-description):
-
-@table @asis
-@item 1 : Filename must be either an absolute filename or blocklist
-This error is returned if a file name is requested which doesn't fit the
-syntax/rules listed in the @ref{Filesystem}.
-
-@item 2 : Bad file or directory type
-This error is returned if a file requested is not a regular file, but
-something like a symbolic link, directory, or FIFO.
-
-@item 3 : Bad or corrupt data while decompressing file
-This error is returned if the run-length decompression code gets an
-internal error. This is usually from a corrupt file.
-
-@item 4 : Bad or incompatible header in compressed file
-This error is returned if the file header for a supposedly compressed
-file is bad.
-
-@item 5 : Partition table invalid or corrupt
-This error is returned if the sanity checks on the integrity of the
-partition table fail. This is a bad sign.
-
-@item 6 : Mismatched or corrupt version of stage1/stage2
-This error is returned if the install command points to incompatible
-or corrupt versions of the stage1 or stage2. It can't detect corruption
-in general, but this is a sanity check on the version numbers, which
-should be correct.
-
-@item 7 : Loading below 1MB is not supported
-This error is returned if the lowest address in a kernel is below the
-1MB boundary. The Linux zImage format is a special case and can be
-handled since it has a fixed loading address and maximum size.
-
-@item 8 : Kernel must be loaded before booting
-This error is returned if GRUB is told to execute the boot sequence
-without having a kernel to start.
-
-@item 9 : Unknown boot failure
-This error is returned if the boot attempt did not succeed for reasons
-which are unknown.
-
-@item 10 : Unsupported Multiboot features requested
-This error is returned when the Multiboot features word in the Multiboot
-header requires a feature that is not recognized. The point of this is
-that the kernel requires special handling which GRUB is probably
-unable to provide.
-
-@item 11 : Unrecognized device string
-This error is returned if a device string was expected, and the string
-encountered didn't fit the syntax/rules listed in the @ref{Filesystem}.
-
-@item 12 : Invalid device requested
-This error is returned if a device string is recognizable but does not
-fall under the other device errors.
-
-@item 13 : Invalid or unsupported executable format
-This error is returned if the kernel image being loaded is not
-recognized as Multiboot or one of the supported native formats (Linux
-zImage or bzImage, FreeBSD, or NetBSD).
-
-@item 14 : Filesystem compatibility error, cannot read whole file
-Some of the filesystem reading code in GRUB has limits on the length of
-the files it can read. This error is returned when the user runs into
-such a limit.
-
-@item 15 : File not found
-This error is returned if the specified file name cannot be found, but
-everything else (like the disk/partition info) is OK.
-
-@item 16 : Inconsistent filesystem structure
-This error is returned by the filesystem code to denote an internal
-error caused by the sanity checks of the filesystem structure on disk
-not matching what it expects. This is usually caused by a corrupt
-filesystem or bugs in the code handling it in GRUB.
-
-@item 17 : Cannot mount selected partition
-This error is returned if the partition requested exists, but the
-filesystem type cannot be recognized by GRUB.
-
-@item 18 : Selected cylinder exceeds maximum supported by BIOS
-This error is returned when a read is attempted at a linear block
-address beyond the end of the BIOS translated area. This generally
-happens if your disk is larger than the BIOS can handle (512MB for
-(E)IDE disks on older machines or larger than 8GB in general).
-
-@item 19 : Linux kernel must be loaded before initrd
-This error is returned if the initrd command is used before loading a
-Linux kernel.
-
-@item 20 : Multiboot kernel must be loaded before modules
-This error is returned if the module load command is used before loading
-a Multiboot kernel. It only makes sense in this case anyway, as GRUB has
-no idea how to communicate the presence of such modules to a
-non-Multiboot-aware kernel.
-
-@item 21 : Selected disk does not exist
-This error is returned if the device part of a device- or full file name
-refers to a disk or BIOS device that is not present or not recognized by
-the BIOS in the system.
-
-@item 22 : No such partition
-This error is returned if a partition is requested in the device part of
-a device- or full file name which isn't on the selected disk.
-
-@item 23 : Error while parsing number
-This error is returned if GRUB was expecting to read a number and
-encountered bad data.
-
-@item 24 : Attempt to access block outside partition
-This error is returned if a linear block address is outside of the disk
-partition. This generally happens because of a corrupt filesystem on the
-disk or a bug in the code handling it in GRUB (it's a great debugging
-tool).
-
-@item 25 : Disk read error
-This error is returned if there is a disk read error when trying to
-probe or read data from a particular disk.
-
-@item 26 : Too many symbolic links
-This error is returned if the link count is beyond the maximum
-(currently 5), possibly the symbolic links are looped.
-
-@item 27 : Unrecognized command
-This error is returned if an unrecognized command is entered on the
-command-line or in a boot sequence section of a configuration file and
-that entry is selected.
-
-@item 28 : Selected item cannot fit into memory
-This error is returned if a kernel, module, or raw file load command is
-either trying to load its data such that it won't fit into memory or it
-is simply too big.
-
-@item 29 : Disk write error
-This error is returned if there is a disk write error when trying to
-write to a particular disk. This would generally only occur during an
-install of set active partition command.
-
-@item 30 : Invalid argument
-This error is returned if an argument specified to a command is invalid.
-
-@item 31 : File is not sector aligned
-This error may occur only when you access a ReiserFS partition by
-block-lists (e.g. the command @command{install}). In this case, you
-should mount the partition with the @samp{-o notail} option.
-
-@item 32 : Must be authenticated
-This error is returned if you try to run a locked entry. You should
-enter a correct password before running such an entry.
-
-@item 33 : Serial device not configured
-This error is returned if you try to change your terminal to a serial
-one before initializing any serial device.
-
-@item 34 : No spare sectors on the disk
-This error is returned if a disk doesn't have enough spare space. This
-happens when you try to embed Stage 1.5 into the unused sectors after
-the MBR, but the first partition starts right after the MBR or they are
-used by EZ-BIOS.

-@node Basic usage
-@section Introduction into the grub shell
-
-You can use the command @command{grub} for installing GRUB under your
-operating systems and for a testbed when you add a new feature into GRUB
-or when fixing a bug. @command{grub} is almost the same as the Stage 2,
-and, in fact, it shares the source code with the Stage 2 and you can use
-the same commands (@pxref{Commands}) in @command{grub}. It is emulated by
-replacing BIOS calls with UNIX system calls and libc functions.
-
-The command @command{grub} accepts the following options:
-
-@table @option
-@item --help
-Print a summary of the command-line options and exit.
-
-@item --version
-Print the version number of GRUB and exit.
-
-@item --verbose
-Print some verbose messages for debugging purpose.
-
-@item --device-map=@var{file}
-Use the device map file @var{file}. The format is described in
-@ref{Device map}.
-
-@item --no-floppy
-Do not probe any floppy drive. This option has no effect if the option
-@option{--device-map} is specified (@pxref{Device map}).
-
-@item --probe-second-floppy
-Probe the second floppy drive. If this option is not specified, the grub
-shell does not probe it, as that sometimes takes a long time. If you
-specify the device map file (@pxref{Device map}), the grub shell just
-ignores this option.
-
-@item --config-file=@var{file}
-Read the configuration file @var{file} instead of
-@file{/boot/grub/menu.lst}. The format is the same as the normal GRUB
-syntax. See @ref{Filesystem}, for more information.
-
-@item --boot-drive=@var{drive}
-Set the stage2 @var{boot_drive} to @var{drive}. This argument should be
-an integer (decimal, octal or hexadecimal).
-
-@item --install-partition=@var{par}
-Set the stage2 @var{install_partition} to @var{par}. This argument
-should be an integer (decimal, octal or hexadecimal).
-
-@item --no-config-file
-Do not use the configuration file even if it can be read.
-
-@item --no-curses
-Do not use the screen handling interface by the curses even if it is
-available.
-
-@item --batch
-This option has the same meaning as @samp{--no-config-file --no-curses}.
-
-@item --read-only
-Disable writing to any disk.
-
-@item --hold
-Wait until a debugger will attach. This option is useful when you want
-to debug the startup code.

-@node Installation under UNIX
-@section How to install GRUB via @command{grub}
-
-The installation procedure is the same as under the @dfn{native} Stage
-2. @xref{Installation}, for more information. The command
-@command{grub}-specific information is described here.
-
-What you should be careful about is @dfn{buffer cache}. @command{grub}
-makes use of raw devices instead of filesystems that your operating
-systems serve, so there exists a potential problem that some cache
-inconsistency may corrupt your filesystems. What we recommend is:
-
-@itemize @bullet
-@item
-If you can unmount drives to which GRUB may write any amount of data,
-unmount them before running @command{grub}.
-
-@item
-If a drive cannot be unmounted but can be mounted with the read-only
-flag, mount it in read-only mode. That should be secure.
-
-@item
-If a drive must be mounted with the read-write flag, make sure that no
-activity is being done on it while the command @command{grub} is
-running.
-
-@item
-Reboot your operating system as soon as possible. This is probably not
-required if you follow the rules above, but reboot is the most secure
-way.
-@end itemize
-
-In addition, enter the command @command{quit} when you finish the
-installation. That is @emph{very important} because @command{quit} makes
-the buffer cache consistent. Do not push @key{C-c}.
-
-If you want to install GRUB non-interactively, specify @samp{--batch}
-option in the command-line. This is a simple example:
-
-@example
-@group
-#!/bin/sh
-
-# Use /usr/sbin/grub if you are on an older system.
-/sbin/grub --batch <<EOT 1>/dev/null 2>/dev/null

-@node Device map
-@section The map between BIOS drives and OS devices
-
-When you specify the option @option{--device-map} (@pxref{Basic usage}),
-the grub shell creates the @dfn{device map file} automatically unless it
-already exists. The file name @file{/boot/grub/device.map} is preferred.
-
-If the device map file exists, the grub shell reads it to map BIOS
-drives to OS devices. This file consists of lines like this:
-
-@example
-@var{device} @var{file}
-@end example
-
-@var{device} is a drive specified in the GRUB syntax (@pxref{Device
-syntax}), and @var{file} is an OS file, which is normally a device
-file.
-
-The reason why the grub shell gives you the device map file is that it
-cannot guess the map between BIOS drives and OS devices correctly in
-some environments. For example, if you exchange the boot sequence
-between IDE and SCSI in your BIOS, it gets the order wrong.
-
-Thus, edit the file if the grub shell makes a mistake. You can put any
-comments in the file if needed, as the grub shell assumes that a line is
-just a comment if the first character is @samp{#}.

-@node Invoking grub-install
-@chapter Invoking grub-install
-
-The program @command{grub-install} installs GRUB on your drive using the
-grub shell (@pxref{Invoking the grub shell}). You must specify the
-device name on which you want to install GRUB, like this:
-
-@example
-grub-install @var{install_device}
-@end example
-
-The device name @var{install_device} is an OS device name or a GRUB
-device name.
-
-@command{grub-install} accepts the following options:
-
-@table @option
-@item --help
-Print a summary of the command-line options and exit.
-
-@item --version
-Print the version number of GRUB and exit.
-
-@item --force-lba
-Force GRUB to use LBA mode even for a buggy BIOS. Use this option only
-if your BIOS doesn't work properly in LBA mode even though it supports
-LBA mode.
-
-@item --root-directory=@var{dir}
-Install GRUB images under the directory @var{dir} instead of the root
-directory. This option is useful when you want to install GRUB into a
-separate partition or a removable disk. Here is an example in which
-you have a separate @dfn{boot} partition which is mounted on
-@file{/boot}:
-
-@example
-@kbd{grub-install --root-directory=/boot hd0}
-@end example
-
-@item --grub-shell=@var{file}
-Use @var{file} as the grub shell. You can append arbitrary options to
-@var{file} after the file name, like this:
-
-@example
-@kbd{grub-install --grub-shell="grub --read-only" /dev/fd0}
-@end example
-
-@item --recheck
-Recheck the device map, even if @file{/boot/grub/device.map} already
-exists. You should use this option whenever you add/remove a disk
-into/from your computer.

-
-The program @command{grub-terminfo} generates a terminfo command from
-a terminfo name (@pxref{terminfo}). The result can be used in the
-configuration file, to define escape sequences. Because GRUB assumes
-that your terminal is vt100-compatible by default, this would be
-useful only if your terminal is uncommon (such as vt52).
-
-@command{grub-terminfo} accepts the following options:
-
-@table @option

-@node Invoking grub-set-default
-@chapter Invoking grub-set-default
-
-The program @command{grub-set-default} sets the default boot entry for
-GRUB. This automatically creates a file named @file{default} under
-your GRUB directory (i.e. @file{/boot/grub}), if it is not
-present. This file is used to determine the default boot entry when
-GRUB boots up your system when you use @samp{default saved} in your
-configuration file (@pxref{default}), and to save next default boot
-entry when you use @samp{savedefault} in a boot entry
-(@pxref{savedefault}).
-
-@command{grub-set-default} accepts the following options:
-
-@table @option
-@item --help
-Print a summary of the command-line options and exit.
-
-@item --version
-Print the version information and exit.
-
-@item --root-directory=@var{dir}
-Use the directory @var{dir} instead of the root directory
-(i.e. @file{/}) to define the location of the default file. This
-is useful when you mount a disk which is used for another system.
-@end table
-
-You must specify a single argument to @command{grub-set-default}. This
-argument is normally the number of a default boot entry. For example,
-if you have this configuration file:
-
-@example
-@group
-default saved
-timeout 10
-
-title GNU/Hurd
-root (hd0,0)
-...
-
-title GNU/Linux
-root (hd0,1)
-...
-@end group
-@end example
-
-and if you want to set the next default boot entry to GNU/Linux, you
-may execute this command:
-
-@example
-@kbd{grub-set-default 1}
-@end example
-
-Because the entry for GNU/Linux is @samp{1}. Note that entries are
-counted from zero. So, if you want to specify GNU/Hurd here, then you
-should specify @samp{0}.

-
-To unbundle GRUB use the instruction:

-@item
-Before getting unsettled, read this manual through and through. Also,
-see the @uref{http://www.gnu.org/software/grub/grub-faq.html, GNU GRUB FAQ}.
-
-@item
-Always mention the information on your GRUB. The version number and the

-options specified to the configure script and your operating system,
-including the versions of gcc and binutils.
-
-@item
-If you have trouble with the installation, inform us of how you
-installed GRUB. Don't omit error messages, if any. Just @samp{GRUB hangs
-up when it boots} is not enough.
-
-The information on your hardware is also essential. These are especially
-important: the geometries and the partition tables of your hard disk
-drives and your BIOS.
-
-@item
-If GRUB cannot boot your operating system, write down
-@emph{everything} you see on the screen. Don't paraphrase them, like
-@samp{The foo OS crashes with GRUB, even though it can boot with the
-bar boot loader just fine}. Mention the commands you executed, the
-messages printed by them, and information on your operating system
-including the version number.
-
-@item
-Explain what you wanted to do. It is very useful to know your purpose
-and your wish, and how GRUB didn't satisfy you.
-
-@item
-If you can investigate the problem yourself, please do. That will give
-you and us much more information on the problem. Attaching a patch is
-even better.
-
-When you attach a patch, make the patch in unified diff format, and
-write ChangeLog entries. But, even when you make a patch, don't forget
-to explain the problem, so that we can understand what your patch is
-for.
-
-@item
-Write down anything that you think might be related. Please understand
-that we often need to reproduce the same problem you encountered in our
-environment. So your information should be sufficient for us to do the
-same thing---Don't forget that we cannot see your computer directly. If
-you are not sure whether to state a fact or leave it out, state it!
-Reporting too many things is much better than omitting something
-important.
-@end enumerate
-
-If you follow the guideline above, submit a report to the

-@node Memory map
-@section The memory map of various components
-
-GRUB consists of two distinct components, called @dfn{stages}, which are
-loaded at different times in the boot process. Because they run
-mutual-exclusively, sometimes a memory area overlaps with another
-memory area. And, even in one stage, a single memory area can be used
-for various purposes, because their usages are mutually exclusive.
-
-Here is the memory map of the various components:
-
-@table @asis
-@item 0 to 4K-1
-BIOS and real mode interrupts
-
-@item 0x07BE to 0x07FF
-Partition table passed to another boot loader
-
-@item down from 8K-1
-Real mode stack
-
-@item 0x2000 to ?
-The optional Stage 1.5 is loaded here
-
-@item 0x2000 to 0x7FFF
-Command-line buffer for Multiboot kernels and modules
-
-@item 0x7C00 to 0x7DFF
-Stage 1 is loaded here by BIOS or another boot loader
-
-@item 0x7F00 to 0x7F42
-LBA drive parameters
-
-@item 0x8000 to ?
-Stage2 is loaded here

-
-
-@node Embedded data
-@section Embedded variables in GRUB
-
-Stage 1 and Stage 2 have embedded variables whose locations are
-well-defined, so that the installation can patch the binary file
-directly without recompilation of the stages.
-
-In Stage 1, these are defined:
-
-@table @code
-@item 0x3E
-The version number (not GRUB's, but the installation mechanism's).
-
-@item 0x40
-The boot drive. If it is 0xFF, use a drive passed by BIOS.
-
-@item 0x41
-The flag for if forcing LBA.
-
-@item 0x42
-The starting address of Stage 2.
-
-@item 0x44
-The first sector of Stage 2.
-
-@item 0x48
-The starting segment of Stage 2.
-
-@item 0x1FE
-The signature (@code{0xAA55}).
-@end table
-
-See the file @file{stage1/stage1.S}, for more information.
-
-In the first sector of Stage 1.5 and Stage 2, the blocklists are
-recorded between @code{firstlist} and @code{lastlist}. The address of
-@code{lastlist} is determined when assembling the file
-@file{stage2/start.S}.
-
-The trick here is that it is actually read backward, and the first
-8-byte blocklist is not read here, but after the pointer is decremented
-8 bytes, then after reading it, it decrements again, reads, and so on,
-until it is finished. The terminating condition is when the number of
-sectors to be read in the next blocklist is zero.
-
-The format of a blocklist can be seen from the example in the code just
-before the @code{firstlist} label. Note that it is always from the
-beginning of the disk, but @emph{not} relative to the partition
-boundaries.
-
-In the second sector of Stage 1.5 and Stage 2, these are defined:
-
-@table @asis
-@item @code{0x6}
-The version number (likewise, the installation mechanism's).
-
-@item @code{0x8}
-The installed partition.
-
-@item @code{0xC}
-The saved entry number.
-
-@item @code{0x10}
-The identifier.
-
-@item @code{0x11}
-The flag for if forcing LBA.
-
-@item @code{0x12}
-The version string (GRUB's).
-
-@item @code{0x12} + @dfn{the length of the version string}
-The name of a configuration file.
-@end table
-
-See the file @file{stage2/asm.S}, for more information.
-
-
-@node Filesystem interface
-@section The generic interface for filesystems
-
-For any particular partition, it is presumed that only one of the
-@dfn{normal} filesystems such as FAT, FFS, or ext2fs can be used, so
-there is a switch table managed by the functions in
-@file{disk_io.c}. The notation is that you can only @dfn{mount} one at a
-time.
-
-The blocklist filesystem has a special place in the system. In addition
-to the @dfn{normal} filesystem (or even without one mounted), you can
-access disk blocks directly (in the indicated partition) via the block
-list notation. Using the blocklist filesystem doesn't effect any other
-filesystem mounts.
-
-The variables which can be read by the filesystem backend are:
-
-@vtable @code
-@item current_drive
-The current BIOS drive number (numbered from 0, if a floppy, and
-numbered from 0x80, if a hard disk).
-
-@item current_partition
-The current partition number.
-
-@item current_slice
-The current partition type.
-
-@item saved_drive
-The @dfn{drive} part of the root device.
-
-@item saved_partition
-The @dfn{partition} part of the root device.
-
-@item part_start
-The current partition starting address, in sectors.
-
-@item part_length
-The current partition length, in sectors.
-
-@item print_possibilities
-True when the @code{dir} function should print the possible completions
-of a file, and false when it should try to actually open a file of that
-name.
-
-@item FSYS_BUF
-Filesystem buffer which is 32K in size, to use in any way which the
-filesystem backend desires.
-@end vtable
-
-The variables which need to be written by a filesystem backend are:
-
-@vtable @code
-@item filepos
-The current position in the file, in sectors.
-
-@strong{Caution:} the value of @var{filepos} can be changed out from
-under the filesystem code in the current implementation. Don't depend on
-it being the same for later calls into the backend code!
-
-@item filemax
-The length of the file.
-
-@item disk_read_func
-The value of @var{disk_read_hook} @emph{only} during reading of data
-for the file, not any other fs data, inodes, FAT tables, whatever, then
-set to @code{NULL} at all other times (it will be @code{NULL} by
-default). If this isn't done correctly, then the @command{testload} and
-@command{install} commands won't work correctly.
-@end vtable
-
-The functions expected to be used by the filesystem backend are:
-
-@ftable @code
-@item devread
-Only read sectors from within a partition. Sector 0 is the first sector
-in the partition.
-
-@item grub_read
-If the backend uses the blocklist code, then @code{grub_read} can be
-used, after setting @var{block_file} to 1.
-
-@item print_a_completion
-If @var{print_possibilities} is true, call @code{print_a_completion} for
-each possible file name. Otherwise, the file name completion won't work.
-@end ftable
-
-The functions expected to be defined by the filesystem backend are
-described at least moderately in the file @file{filesys.h}. Their usage
-is fairly evident from their use in the functions in @file{disk_io.c},
-look for the use of the @var{fsys_table} array.
-
-@strong{Caution:} The semantics are such that then @samp{mount}ing the
-filesystem, presume the filesystem buffer @code{FSYS_BUF} is corrupted,
-and (re-)load all important contents. When opening and reading a file,
-presume that the data from the @samp{mount} is available, and doesn't
-get corrupted by the open/read (i.e. multiple opens and/or reads will be
-done with only one mount if in the same filesystem).
-
-
-@node Command interface
-@section The generic interface for built-ins
-
-GRUB built-in commands are defined in a uniform interface, whether
-they are menu-specific or can be used anywhere. The definition of a
-built-in command consists of two parts: the code itself and the table of
-the information.
-
-The code must be a function which takes two arguments, a command-line
-string and flags, and returns an @samp{int} value. The @dfn{flags}
-argument specifies how the function is called, using a bit mask. The
-return value must be zero if successful, otherwise non-zero. So it is
-normally enough to return @var{errnum}.
-
-The table of the information is represented by the structure
-@code{struct builtin}, which contains the name of the command, a pointer
-to the function, flags, a short description of the command and a long
-description of the command. Since the descriptions are used only for
-help messages interactively, you don't have to define them, if the
-command may not be called interactively (such as @command{title}).
-
-The table is finally registered in the table @var{builtin_table}, so
-that @code{run_script} and @code{enter_cmdline} can find the
-command. See the files @file{cmdline.c} and @file{builtins.c}, for more
-details.
-
-
-@node Bootstrap tricks
-@section The bootstrap mechanism used in GRUB
-
-The disk space can be used in a boot loader is very restricted because
-a MBR (@pxref{MBR}) is only 512 bytes but it also contains a partition
-table (@pxref{Partition table}) and a BPB. So the question is how to
-make a boot loader code enough small to be fit in a MBR.
-
-However, GRUB is a very large program, so we break GRUB into 2 (or 3)
-distinct components, @dfn{Stage 1} and @dfn{Stage 2} (and optionally
-@dfn{Stage 1.5}). @xref{Memory map}, for more information.
-
-We embed Stage 1 in a MBR or in the boot sector of a partition, and
-place Stage 2 in a filesystem. The optional Stage 1.5 can be installed
-in a filesystem, in the @dfn{boot loader} area in a FFS or a ReiserFS,
-and in the sectors right after a MBR, because Stage 1.5 is enough small
-and the sectors right after a MBR is normally an unused region. The size
-of this region is the number of sectors per head minus 1.
-
-Thus, all Stage1 must do is just load Stage2 or Stage1.5. But even if
-Stage 1 needs not to support the user interface or the filesystem
-interface, it is impossible to make Stage 1 less than 400 bytes, because
-GRUB should support both the CHS mode and the LBA mode (@pxref{Low-level
-disk I/O}).
-
-The solution used by GRUB is that Stage 1 loads only the first sector of
-Stage 2 (or Stage 1.5) and Stage 2 itself loads the rest. The flow of
-Stage 1 is:
-
-@enumerate
-@item
-Initialize the system briefly.
-
-@item
-Detect the geometry and the accessing mode of the @dfn{loading drive}.
-
-@item
-Load the first sector of Stage 2.
-
-@item
-Jump to the starting address of the Stage 2.
-@end enumerate
-
-The flow of Stage 2 (and Stage 1.5) is:
-
-@enumerate
-@item
-Load the rest of itself to the real starting address, that is, the
-starting address plus 512 bytes. The blocklists are stored in the last
-part of the first sector.
-
-@item
-Long jump to the real starting address.
-@end enumerate
-
-Note that Stage 2 (or Stage 1.5) does not probe the geometry
-or the accessing mode of the @dfn{loading drive}, since Stage 1 has
-already probed them.

-segregate features and produce many patches.
-
-@item
-Use as late code as possible, for the original code. The CVS repository
-always has the current version (@pxref{Obtaining and Building GRUB}).
-
-@item
-Write ChangeLog entries. @xref{Change Logs, , Change Logs, standards,
-GNU Coding Standards}, if you don't know how to write ChangeLog.
-
-@item
-Make patches in unified diff format. @samp{diff -urN} is appropriate in
-most cases.

-@item
-Don't make patches reversely. Reverse patches are difficult to read and

-Be careful enough of the license term and the copyright. Because GRUB

-% tex foo.texi
-% texindex foo.??
-% tex foo.texi
-% tex foo.texi
-% dvips foo.dvi -o # or whatever; this makes foo.ps.
-% The extra TeX runs get the cross-reference information correct.

-% @multitable macros
-% Amy Hendrickson, 8/18/94, 3/6/96
-%
-% @multitable ... @end multitable will make as many columns as desired.
-% Contents of each column will wrap at width given in preamble. Width
-% can be specified either with sample text given in a template line,
-% or in percent of \hsize, the current width of text on page.
-
-% Table can continue over pages but will only break between lines.
-
-% To make preamble:
-%
-% Either define widths of columns in terms of percent of \hsize:
-% @multitable @columnfractions .25 .3 .45
-% @item ...
-%
-% Numbers following @columnfractions are the percent of the total
-% current hsize to be used for each column. You may use as many
-% columns as desired.
-
-
-% Or use a template:
-% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
-% @item ...
-% using the widest term desired in each column.
-
-% Each new table line starts with @item, each subsequent new column
-% starts with @tab. Empty columns may be produced by supplying @tab's
-% with nothing between them for as many times as empty columns are needed,
-% ie, @tab@tab@tab will produce two empty columns.
-
-% @item, @tab do not need to be on their own lines, but it will not hurt
-% if they are.
-
-% Sample multitable:
-
-% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
-% @item first col stuff @tab second col stuff @tab third col
-% @item
-% first col stuff
-% @tab
-% second col stuff
-% @tab
-% third col
-% @item first col stuff @tab second col stuff
-% @tab Many paragraphs of text may be used in any column.
-%
-% They will wrap at the width determined by the template.
-% @item@tab@tab This will be in third column.
-% @end multitable
-
-% Default dimensions may be reset by user.
-% @multitableparskip is vertical space between paragraphs in table.
-% @multitableparindent is paragraph indent in table.
-% @multitablecolmargin is horizontal space to be left between columns.
-% @multitablelinespace is space to leave between table items, baseline
-% to baseline.

- to be given in any order, even with programs that were not written to
- expect this.
-
- RETURN_IN_ORDER is an option available to programs that were written
- to expect options and other ARGV-elements in any order and that care about
- the ordering of the two. We describe each non-option ARGV-element
- as if it were the argument of an option with character code 1.
- Using `-' as the first character of the list of option characters
- selects this mode of operation.
-
- The special argument `--' forces an end of option-scanning regardless
- of the value of `ordering'. In the case of RETURN_IN_ORDER, only

- If an element of ARGV starts with '-', and is not exactly "-" or "--",
- then it is an option element. The characters of this element
- (aside from the initial '-') are option characters. If `getopt'
- is called repeatedly, it returns successively each of the option characters
- from each of the option elements.
-
- If `getopt' finds another option character, it returns that character,
- updating `optind' and `nextchar' so that the next call to `getopt' can
- resume the scan with the following option character or ARGV-element.
-
- If there are no more option characters, `getopt' returns -1.
- Then `optind' is the index in ARGV of the first ARGV-element
- that is not an option. (The ARGV-elements have been permuted
- so that those that are not options now come last.)
-
- OPTSTRING is a string containing the legitimate option characters.
- If an option character is seen that is not listed in OPTSTRING,
- return '?' after printing an error message. If you set `opterr' to
- zero, the error message is suppressed but we still return '?'.
-
- If a char in OPTSTRING is followed by a colon, that means it wants an arg,
- so the following text in the same ARGV-element, or the text of the following
- ARGV-element, is returned in `optarg'. Two colons mean an option that
- wants an optional arg; if there is text in the current ARGV-element,
- it is returned in `optarg', otherwise `optarg' is set to zero.
-
- If OPTSTRING starts with `-' or `+', it requests different methods of
- handling the non-option ARGV-elements.
- See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
-
- Long-named options begin with `--' instead of `-'.
- Their names may be abbreviated as long as the abbreviation is unique
- or is an exact match for some defined option. If they have an
- argument, it follows the option name in the same ARGV-element, separated
- from the option name by a `=', or else the in next ARGV-element.
- When `getopt' finds a long-named option, it returns 0 if that option's
- `flag' field is nonzero, the value of the option's `val' field
- if the `flag' field is zero.
-
- The elements of ARGV aren't really const, because we permute them.
- But we pretend they're const in the prototype to be compatible
- with other systems.
-
- LONGOPTS is a vector of `struct option' terminated by an
- element containing a name which is zero.
-
- LONGIND returns the index in LONGOPT of the long-named option found.
- It is only valid when a long-named option has been found by the most
- recent call.

-
-I OVERVIEW
-
- The 3c90X series ethernet cards are a group of high-performance busmaster
- DMA cards from 3Com. This particular driver supports both the 3c90x and
- the 3c90xB revision cards. 3C90xC family support has been tested to some
- degree but not extensively.
-
- Here's the licensing information:
-
- This program Copyright (C) 1999 LightSys Technology Services, Inc.
- Portions Copyright (C) 1999 Steve Smith.

- provided that the above copyright message and this text are included in the
- documentation of any binary-only distributions. This program is
- distributed WITHOUT ANY WARRANTY, without even the warranty of FITNESS FOR
- A PARTICULAR PURPOSE or MERCHANTABILITY. Please read the associated
- documentation "3c90x.txt" before compiling and using this driver.
-
-
-II FLASH PROMS
-
- The 3c90xB cards, according to the 3Com documentation, only accept the
- following flash memory chips:
-
- Atmel AT29C512 (64 kilobyte)
- Atmel AT29C010 (128 kilobyte)
-
- The 3c90x cards, according to the 3Com documentation, accept the
- following flash memory chips capacities:
-
- 64 kb (8 kB)
- 128 kb (16 kB)
- 256 kb (32 kB) and
- 512 kb (64 kB)
-
- Atmel AT29C512 (64 kilobyte) chips are specifically listed for both
- adapters, but flashing on the 3c905b cards would only be supported
- through the Atmel parts. Any device, of the supported size, should
- be supported when programmed by a dedicated PROM programmer (e.g.
- not the card).
-
- To use this driver in such a PROM, visit Atmel's web site and download
- their .PDF file containing a list of their distributors. Contact the
- distributors for pricing information. The prices are quite reasonable
- (about $3 US each for the 64 kB part), and are comparable to what one would
- expect for similarly sized standard EPROMs. And, the flash chips are much
- easier to work with, as they don't need to be UV-erased to be reprogrammed.
- The 3C905B card actually provides a method to program the flash memory
- while it is resident on board the card itself; if someone would like to
- write a small DOS program to do the programming, I can provide the
- information about the registers and so forth.
-
- A utility program, 3c90xutil, is provided with Etherboot in the 'contrib'
- directory that allows for the on-board flashing of the ROM while Linux
- is running. The program has been successfully used under Linux, but I
- have heard problem reports of its use under FreeBSD. Anyone willing to
- make it work under FreeBSD is more than welcome to do so!
-
- You also have the option of using EPROM chips - the 3C905B-TX-NM has been
- successfully tested with 27C256 (32kB) and 27C512 (64kB) chips with a
- specified access time of 100ns and faster.
-
-
-III GENERAL USE
-
- Normally, the basic procedure for using this driver is as follows:
-
- 1. Run the 3c90xcfg program on the driver diskette to enable the
- boot PROM and set it to 64k or 128k, as appropriate.
- 2. Build the appropriate 3c90x.fd0 or 3c90x.fd0 floppy image with
- possibly the value CFG_3C90X_XCVR defined to the transceiver type that
- you want to use (i.e., 10/100 rj45, AUI, coax, MII).
- 3. Run the floppy image on the PC to be network booted, to get
- it configured, and to verify that it will boot properly.
- 4. Build the 3c90x.rom or 3c90x.lzrom PROM image and program
- it into the flash or EPROM memory chip.
- 5. Put the PROM in the ethernet card, boot and enable 'boot from
- network first' in the system BIOS, save and reboot.
-
- Here are some issues to be aware of:
-
- 1. If you experience crashes or different behaviour when using the
- boot PROM, add the setting CFG_3C90X_BOOTROM_FIX and go through the
- steps 2-5 above. This works around a bug in some 3c905B cards (see
- below), but has some side-effects which may not be desirable.
- Please note that you have to boot off a floppy (not PROM!) once for
- this fix to take effect.
- 2. The possible need to manually set the CFG_3C90X_XCVR value to
- configure the transceiver type. Values are listed below.
- 3. The possible need to define CFG_3C90X_PRESERVE_XCVR for use in
- operating systems that don't intelligently determine the
- transceiver type.
-
- Some things that are on the 'To-Do' list, perhaps for me, but perhaps
- for any other volunteers out there:
-
- 1. Extend the driver to fully implement the auto-select
- algorithm if the card has multiple media ports.
- 2. Fix any bugs in the code <grin>....
- 3. Extend the driver to support the 3c905c revision cards
- "officially". Right now, the support has been primarily empirical
- and not based on 3c905C documentation.
-
- Now for the details....
-
- This driver has been tested on roughly 300 systems. The main two
- configuration issues to contend with are:
-
- 1. Ensure that PCI Busmastering is enabled for the adapter (configured
- in the CMOS setup)
- 2. Some systems don't work properly with the adapter when plug and
- play OS is enabled; I always set it to "No" or "Disabled" -- this makes
- it easier and really doesn't adversely affect anything.
-
- Roughly 95% of the systems worked when configured properly. A few
- have issues with booting locally once the boot PROM has been installed
- (this number has been less than 2%). Other configuration issues that
- to check:
-
- 1. Newer BIOS's actually work correctly with the network boot order.
- Set the network adapter first. Most older BIOS's automatically go to
- the network boot PROM first.
- 2. For systems where the adapter was already installed and is just
- having the PROM installed, try setting the "reset configuration data"
- to yes in the CMOS setup if the BIOS isn't seen at first. If your BIOS
- doesn't have this option, remove the card, start the system, shut down,
- install the card and restart (or switch to a different PCI slot).
- 3. Make sure the CMOS security settings aren't preventing a boot.
-
- The 3c905B cards have a significant 'bug' that relates to the flash prom:
- unless the card is set internally to the MII transceiver, it will only
- read the first 8k of the PROM image. Don't ask why -- it seems really
- obscure, but it has to do with the way they mux'd the address lines
- from the PCI bus to the ROM. Unfortunately, most of us are not using
- MII transceivers, and even the .lzrom image ends up being just a little
- bit larger than 8k. Note that the workaround for this is disabled by
- default, because the Windows NT 4.0 driver does not like it (no packets
- are transmitted).
-
- So, the solution that I've used is to internally set the card's nvram
- configuration to use MII when it boots. The 3c905b driver does this
- automatically. This way, the 16k prom image can be loaded into memory,
- and then the 3c905b driver can set the temporary configuration of the
- card to an appropriate value, either configurable by the user or chosen
- by the driver.
-
- To enable the 3c905B bugfix, which is necessary for these cards when
- booting from the Flash ROM, define -DCFG_3C90X_BOOTROM_FIX when building,
- create a floppy image and boot it once.
- Thereafter, the card should accept the larger prom image.
-
- The driver should choose an appropriate transceiver on the card. However,
- if it doesn't on your card or if you need to, for instance, set your
- card to 10mbps when connected to an unmanaged 10/100 hub, you can specify
- which transceiver you want to use. To do this, build the 3c905b.fd0
- image with -DCFG_3C90X_XCVR=x, where 'x' is one of the following
- values:
-
- 0 10Base-T
- 1 10mbps AUI
- 3 10Base-2 (thinnet/coax)
- 4 100Base-TX
- 5 100Base-FX
- 6 MII
- 8 Auto-negotiation 10Base-T / 100Base-TX (usually the default)
- 9 MII External MAC Mode
- 255 Allow driver to choose an 'appropriate' media port.
-
- Then proceed from step 2 in the above 'general use' instructions. The
- .rom image can be built with CFG_3C90X_XCVR set to a value, but you
- normally don't want to do this, since it is easier to change the
- transceiver type by rebuilding a new floppy, changing the BIOS to floppy
- boot, booting, and then changing the BIOS back to network boot. If
- CFG_3C90X_XCVR is not set in a particular build, it just uses the
- current configuration (either its 'best guess' or whatever the stored
- CFG_3C90X_XCVR value was from the last time it was set).
-
- [[ Note for the more technically inclined: The CFG_3C90X_XCVR value is
- programmed into a register in the card's NVRAM that was reserved for
- LanWorks PROM images to use. When the driver boots, the card comes
- up in MII mode, and the driver checks the LanWorks register to find
- out if the user specified a transceiver type. If it finds that
- information, it uses that, otherwise it picks a transceiver that the
- card has based on the 3c905b's MediaOptions register. This driver isn't
- quite smart enough to always determine which media port is actually
- _connected_; maybe someone else would like to take on that task (it
- actually involves sending a self-directed packet and seeing if it
- comes back. IF it does, that port is connected). ]]
-
- Another issue to keep in mind is that it is possible that some OS'es
- might not be happy with the way I've handled the PROM-image hack with
- setting MII mode on bootup. Linux 2.0.35 does not have this problem.
- Behavior of other systems may vary. The 3com documentation specifically
- says that, at least with the card that I have, the device driver in the
- OS should auto-select the media port, so other drivers should work fine
- with this 'hack'. However, if yours doesn't seem to, you can try defining
- CFG_3C90X_PRESERVE_XCVR when building to cause Etherboot to keep the
- working setting (that allowed the bootp/tftp process) across the eth_reset
- operation.
-
-
-IV FOR DEVELOPERS....
-
- If you would like to fix/extend/etc. this driver, feel free to do so; just
- be sure you can test the modified version on the 3c905B-TX cards that the
- driver was originally designed for. This section of this document gives
- some information that might be relevant to a programmer.
-
- A. Main Entry Point
-
- a3c90x_probe is the main entry point for this driver. It is referred
- to in an array in 'config.c'.
-
- B. Other Important Functions
-
- The functions a3c90x_transmit, a3c90x_poll, a3c90x_reset, and
- a3c90x_disable are static functions that EtherBoot finds out about
- as a result of a3c90x_probe setting entries in the nic structure
- for them. The EtherBoot framework does not use interrupts. It is
- polled. All transmit and receive operations are initiated by the
- etherboot framework, not by an interrupt or by the driver.
-
- C. Internal Functions
-
- The following functions are internal to the driver:
-
- a3c90x_internal_IssueCommand - sends a command to the 3c905b card.
- a3c90x_internal_SetWindow - shifts between one of eight register
- windows onboard the 3c90x. The bottom 16 bytes of the card's
- I/O space are multiplexed among 128 bytes, only 16 of which are
- visible at any one time. This SetWindow function selects one of
- the eight sets.
- a3c90x_internal_ReadEeprom - reads a word (16 bits) from the
- card's onboard nvram. This is NOT the BIOS boot rom. This is
- where the card stores such things as its hardware address.
- a3c90x_internal_WriteEeprom - writes a word (16 bits) to the
- card's nvram, and recomputes the eeprom checksum.
- a3c90x_internal_WriteEepromWord - writes a word (16 bits) to the
- card's nvram. Used by the above routine.
- a3c90x_internal_WriteEepromWord - writes a word (16 bits) to the
- card's nvram. Used by the above routine.
-
- D. Globals
-
- All global variables are inside a global structure named INF_3C90X.
- So, wherever you see that structure referenced, you know the variable
- is a global. Just keeps things a little neater.
-
- E. Enumerations
-
- There are quite a few enumerated type definitions for registers and
- so forth, many for registers that I didn't even touch in the driver.
- Register types start with 'reg', window numbers (for SetWindow)
- start with 'win', and commands (for IssueCommand) start with 'cmd'.
- Register offsets also include an indication in the name as to the
- size of the register (_b = byte, _w = word, _l = long), and which
- window the register is in, if it is windowed (0-7).
-
- F. Why the 'a3c90x' name?
-
- I had to come up with a letter at the beginning of all of the
- identifiers, since 3com so conveniently had their name start with a
- number. Another driver used 't' (for 'three'?); I chose 'a' for
- no reason at all.
-
-Addendum by Jorge L. deLyra <delyra@latt.if.usp.br>, 22Nov2000 re
-working around the 3C905 hardware bug mentioned above:
-
-Use this floppy to fix any 3COM model 3C905B PCI 10/100 Ethernet cards
-that fail to load and run the boot program the first time around. If
-they have a "Lucent" rather than a "Broadcom" chipset these cards have
-a configuration bug that causes a hang when trying to load the boot
-program from the PROM, if you try to use them right out of the box.
-
-The boot program in this floppy is the file named 3c905b-tpo100.rom
-from Etherboot version 4.6.10, compiled with the bugfix parameter
-
- CFG_3C90X_BOOTROM_FIX
-
-You have to take the chip off the card and boot the system once using
-this floppy. Once loaded from the floppy, the boot program will access
-the card and change some setting in it, correcting the problem. After
-that you may use either this boot program or the normal one, compiled
-without this bugfix parameter, to boot the machine from the PROM chip.
-
-[Any recent Etherboot version should do, not just 4.6.10 - Ed.]

-You can use the netboot support to download OS images from a network.
-Nearly all the device drivers are coming from the network-based boot
-loader, Etherboot. Please visit its web page. They have rich
-documentations so you will be able to get useful information from there.
-The URL is <http://etherboot.sourceforge.net/>.
-
-These below are common options for configure. Perhaps you may not need
-to specify them.
-
---disable-packet-retransmission
- Turns off packet retransmission. Use it on an empty network, where
- no packet collision can happen.
-
---enable-pci-direct
- Define this for PCI BIOSes that do not implement BIOS32 or not
- correctly.
-
---enable-diskless
- Enable the diskless support. If specified, you will get two optional
- images, called "nbgrub" and "pxegrub". The former is the ``Net Boot
- Image Proposal'' format, which is used by Etherboot and Netboot, while
- the latter is the ``Preboot Execution Environment" format, which is
- used by a PXE ROM. You may buy a PXE ROM from some companies.
-
-Here is the information about the device drivers. They are all disabled
-by default, so you must specify configure options to enable drivers you
-want to use. Some drivers have extra per-driver options, so the extra
-options are also described below.
-
-Caution: You should enable them as you need. Don't enable any
-unnecessary driver, because GRUB might crash if you include too many
-drivers at the same time.

- Russ Nelson, January 2000
-
- ChangeLog:
-
- Thu Dec 6 22:40:00 1996 Markus Gutschke <gutschk@math.uni-muenster.de>
-
- * disabled all "advanced" features; this should make the code more reliable
-
- * reorganized the reset function
-
- * always reset the address port, so that autoprobing will continue working
-
- * some cosmetic changes
-
- * 2.5
-
- Thu Dec 5 21:00:00 1996 Markus Gutschke <gutschk@math.uni-muenster.de>
-
- * tested the code against a CS8900 card
-
- * lots of minor bug fixes and adjustments
-
- * this is the first release, that actually works! it still requires some
- changes in order to be more tolerant to different environments
-
- * 4
-
- Fri Nov 22 23:00:00 1996 Markus Gutschke <gutschk@math.uni-muenster.de>
-
- * read the manuals for the CS89x0 chipsets and took note of all the
- changes that will be neccessary in order to adapt Russel Nelson's code
- to the requirements of a BOOT-Prom
-
- * 6
-
- Thu Nov 19 22:00:00 1996 Markus Gutschke <gutschk@math.uni-muenster.de>
-
- * Synched with Russel Nelson's current code (v1.00)
-
- * 2
-
- Thu Nov 12 18:00:00 1996 Markus Gutschke <gutschk@math.uni-muenster.de>
-
- * Cleaned up some of the code and tried to optimize the code size.
-
- * 1.5
-
- Sun Nov 10 16:30:00 1996 Markus Gutschke <gutschk@math.uni-muenster.de>
-
- * First experimental release. This code compiles fine, but I
- have no way of testing whether it actually works.
-
- * I did not (yet) bother to make the code 16bit aware, so for
- the time being, it will only work for Etherboot/32.
-
- * 12

- 19 OCT 2000 Sten 1.00
- Different half and full duplex mode
- Do the different programming for DM9801/DM9802
-
- 12 OCT 2000 Sten 0.90
- This driver was ported from tulip driver and it
- has the following difference.
- Changed symbol tulip/TULIP to davicom/DAVICOM
- Deleted some code that did not use in this driver.
- Used chain-strcture to replace ring structure
- for both TX/RX descriptor.
- Allocated two tx descriptor.
- According current media mode to set operating
- register(CR6)

- This driver is written for the Digital Equipment Corporation series
- of DEPCA and EtherWORKS ethernet cards:
-
- DEPCA (the original)
- DE100
- DE101
- DE200 Turbo
- DE201 Turbo
- DE202 Turbo (TP BNC)
- DE210
- DE422 (EISA)
-
- The driver has been tested on DE100, DE200 and DE202 cards in a
- relatively busy network. The DE422 has been tested a little.
-
- This driver will NOT work for the DE203, DE204 and DE205 series of
- cards, since they have a new custom ASIC in place of the AMD LANCE
- chip. See the 'ewrk3.c' driver in the Linux source tree for running
- those cards.
-
- I have benchmarked the driver with a DE100 at 595kB/s to (542kB/s from)
- a DECstation 5000/200.

- The driver was originally based on the 'lance.c' driver from Donald
- Becker which is included with the standard driver distribution for
- linux. V0.4 is a complete re-write with only the kernel interface
- remaining from the original code.

-
- Peter Bauer's depca.c (V0.5) was referred to when debugging V0.1 of this
- driver.
-
- The original DEPCA card requires that the ethernet ROM address counter
- be enabled to count and has an 8 bit NICSR. The ROM counter enabling is
- only done when a 0x08 is read as the first address octet (to minimise
- the chances of writing over some other hardware's I/O register). The
- NICSR accesses have been changed to byte accesses for all the cards
- supported by this driver, since there is only one useful bit in the MSB
- (remote boot timeout) and it is not used. Also, there is a maximum of
- only 48kB network RAM for this card. My thanks to Torbjorn Lindh for
- help debugging all this (and holding my feet to the fire until I got it
- right).
-
- The DE200 series boards have on-board 64kB RAM for use as a shared
- memory network buffer. Only the DE100 cards make use of a 2kB buffer
- mode which has not been implemented in this driver (only the 32kB and
- 64kB modes are supported [16kB/48kB for the original DEPCA]).
-
- At the most only 2 DEPCA cards can be supported on the ISA bus because
- there is only provision for two I/O base addresses on each card (0x300
- and 0x200). The I/O address is detected by searching for a byte sequence
- in the Ethernet station address PROM at the expected I/O address for the
- Ethernet PROM. The shared memory base address is 'autoprobed' by
- looking for the self test PROM and detecting the card name. When a
- second DEPCA is detected, information is placed in the base_addr
- variable of the next device structure (which is created if necessary),
- thus enabling ethif_probe initialization for the device. More than 2
- EISA cards can be supported, but care will be needed assigning the
- shared memory to ensure that each slot has the correct IRQ, I/O address
- and shared memory address assigned.
-
- ************************************************************************
-
- NOTE: If you are using two ISA DEPCAs, it is important that you assign
- the base memory addresses correctly. The driver autoprobes I/O 0x300
- then 0x200. The base memory address for the first device must be less
- than that of the second so that the auto probe will correctly assign the
- I/O and memory addresses on the same card. I can't think of a way to do
- this unambiguously at the moment, since there is nothing on the cards to
- tie I/O and memory information together.
-
- I am unable to test 2 cards together for now, so this code is
- unchecked. All reports, good or bad, are welcome.
-
- ************************************************************************
-
- The board IRQ setting must be at an unused IRQ which is auto-probed
- using Donald Becker's autoprobe routines. DEPCA and DE100 board IRQs are
- {2,3,4,5,7}, whereas the DE200 is at {5,9,10,11,15}. Note that IRQ2 is
- really IRQ9 in machines with 16 IRQ lines.
-
- No 16MB memory limitation should exist with this driver as DMA is not
- used and the common memory area is in low memory on the network card (my
- current system has 20MB and I've not had problems yet).
-
- The ability to load this driver as a loadable module has been added. To
- utilise this ability, you have to do <8 things:
-
- 0) have a copy of the loadable modules code installed on your system.
- 1) copy depca.c from the /linux/drivers/net directory to your favourite
- temporary directory.
- 2) if you wish, edit the source code near line 1530 to reflect the I/O
- address and IRQ you're using (see also 5).
- 3) compile depca.c, but include -DMODULE in the command line to ensure
- that the correct bits are compiled (see end of source code).
- 4) if you are wanting to add a new card, goto 5. Otherwise, recompile a
- kernel with the depca configuration turned off and reboot.
- 5) insmod depca.o [irq=7] [io=0x200] [mem=0xd0000] [adapter_name=DE100]
- [Alan Cox: Changed the code to allow command line irq/io assignments]
- [Dave Davies: Changed the code to allow command line mem/name
- assignments]
- 6) run the net startup bits for your eth?? interface manually
- (usually /etc/rc.inet[12] at boot time).
- 7) enjoy!
-
- Note that autoprobing is not allowed in loadable modules - the system is
- already up and running and you're messing with interrupts.
-
- To unload a module, turn off the associated interface
- 'ifconfig eth?? down' then 'rmmod depca'.
-
- To assign a base memory address for the shared memory when running as a
- loadable module, see 5 above. To include the adapter name (if you have
- no PROM but know the card name) also see 5 above. Note that this last
- option will not work with kernel built-in depca's.
-
- The shared memory assignment for a loadable module makes sense to avoid
- the 'memory autoprobe' picking the wrong shared memory (for the case of
- 2 depca's in a PC).
-
- ************************************************************************
- Support for MCA EtherWORKS cards added 11-3-98.
- Verified to work with up to 2 DE212 cards in a system (although not
- fully stress-tested).
-
- Currently known bugs/limitations:
-
- Note: with the MCA stuff as a module, it trusts the MCA configuration,
- not the command line for IRQ and memory address. You can
- specify them if you want, but it will throw your values out.
- You still have to pass the IO address it was configured as
- though.

-This board accepts a 32 pin EEPROM (29C256), however a test with a
-27C010 shows that this EPROM also works in the socket, but it's not clear
-how repeatably. The two top address pins appear to be held low, thus
-the bottom 32kB of the 27C010 is visible in the CPU's address space.
-To be sure you could put 4 copies of the code in the 27C010, then
-it doesn't matter whether the extra lines are held low or high, just
-hopefully not floating as CMOS chips don't like floating inputs.
-
-Be careful with seating the EPROM as the socket on my board actually
-has 34 pins, the top row of 2 are not used.

- *
- * This is the etherboot intel etherexpress Pro/100B driver.
- *
- * It was written from scratch, with Donald Beckers eepro100.c kernel
- * driver as a guideline. Mostly the 82557 related definitions and the
- * lower level routines have been cut-and-pasted into this source.
- *
- * The driver was finished before Intel got the NDA out of the closet.
- * I still don't have the docs.
- * */
-
-/* Philosophy of this driver.
- *
- * Probing:
- *
- * Using the pci.c functions of the Etherboot code, the 82557 chip is detected.
- * It is verified that the BIOS initialized everything properly and if
- * something is missing it is done now.
- *
- *
- * Initialization:
- *
- *
- * The chip is then initialized to "know" its ethernet address, and to
- * start recieving packets. The Linux driver has a whole transmit and
- * recieve ring of buffers. This is neat if you need high performance:
- * you can write the buffers asynchronously to the chip reading the
- * buffers and transmitting them over the network. Performance is NOT
- * an issue here. We can boot a 400k kernel in about two
- * seconds. (Theory: 0.4 seconds). Booting a system is going to take
- * about half a minute anyway, so getting 10 times closer to the
- * theoretical limit is going to make a difference of a few percent.
- *
- *
- * Transmitting and recieving.
- *
- * We have only one transmit descriptor. It has two buffer descriptors:
- * one for the header, and the other for the data.
- * We have only one receive buffer. The chip is told to recieve packets,
- * and suspend itself once it got one. The recieve (poll) routine simply
- * looks at the recieve buffer to see if there is already a packet there.
- * if there is, the buffer is copied, and the reciever is restarted.
- *
- * Caveats:
- *
- * The etherboot framework moves the code to the 32k segment from
- * 0x98000 to 0xa0000. There is just a little room between the end of
- * this driver and the 0xa0000 address. If you compile in too many
- * features, this will overflow.
- * The number under "hex" in the output of size that scrolls by while
- * compiling should be less than 8000. Maybe even the stack is up there,
- * so that you need even more headroom.
- */
-
-/* The etherboot authors seem to dislike the argument ordering in
- * outb macros that Linux uses. I disklike the confusion that this
- * has caused even more.... This file uses the Linux argument ordering. */

- thus the unusual location of the SCB at 0x0008.
-
- Even with the additional "don't care" values, doing it this way takes less
- program space than initializing the individual tables, and I feel it's much
- cleaner.
-
- The databook is particularly useless for the first two structures, I had
- to use the Crynwr driver as an example.
-
- The memory setup is as follows:
-*/

-#define RX_BUF_SIZE (1518+14+18) /* packet+header+RBD */

-
-/*
- That's it: only 86 bytes to set up the beast, including every extra
- command available. The 170 byte buffer at DUMP_DATA is shared between the
- Dump command (called only by the diagnostic program) and the SetMulticastList
- command.
-
- To complete the memory setup you only have to write the station address at
- SA_OFFSET and create the Tx & Rx buffer lists.
-
- The Tx command chain and buffer list is setup as follows:
- A Tx command table, with the data buffer pointing to...
- A Tx data buffer descriptor. The packet is in a single buffer, rather than
- chaining together several smaller buffers.
- A NoOp command, which initially points to itself,
- And the packet data.
-
- A transmit is done by filling in the Tx command table and data buffer,
- re-writing the NoOp command, and finally changing the offset of the last
- command to point to the current Tx command. When the Tx command is finished,
- it jumps to the NoOp, when it loops until the next Tx command changes the
- "link offset" in the NoOp. This way the 82586 never has to go through the
- slow restart sequence.
-
- The Rx buffer list is set up in the obvious ring structure. We have enough
- memory (and low enough interrupt latency) that we can avoid the complicated
- Rx buffer linked lists by alway associating a full-size Rx data buffer with
- each Rx data frame.
-
- I currently use one transmit buffer starting at TX_BUF_START (0x0100), and
- use the rest of memory, from RX_BUF_START to RX_BUF_END, for Rx buffers.

- Etherboot DEC Tulip driver

- FreeBSD netboot DEC 21143 driver
-
- Author: David Sharp
- date: Nov/98
-
- Known to work on DEC DE500 using 21143-PC chipset.
- Even on cards with the same chipset there can be
- incompatablity problems with the way media selection
- and status LED settings are done. See comments below.
-
- Some code fragments were taken from verious places,
- Ken Yap's etherboot, FreeBSD's if_de.c, and various
- Linux related files. DEC's manuals for the 21143 and
- SROM format were very helpful. The Linux de driver
- development page has a number of links to useful
- related information. Have a look at:
- ftp://cesdis.gsfc.nasa.gov/pub/linux/drivers/tulip-devel.html

- This software may be used and distributed according to the terms

-
- 06 Apr 2001 ken_yap@users.sourceforge.net (Ken Yap)
- Following email from Hyun-Joon Cha, added a disable routine, otherwise
- NIC remains live and can crash the kernel later.
-
- 4 Feb 2000 espenlaub@informatik.uni-ulm.de (Klaus Espenlaub)
- Shuffled things around, removed the leftovers from the 8129 support
- that was in the Linux driver and added a bit more 8139 definitions.
- Moved the 8K receive buffer to a fixed, available address outside the
- 0x98000-0x9ffff range. This is a bit of a hack, but currently the only
- way to make room for the Etherboot features that need substantial amounts
- of code like the ANSI console support. Currently the buffer is just below
- 0x10000, so this even conforms to the tagged boot image specification,
- which reserves the ranges 0x00000-0x10000 and 0x98000-0xA0000. My
- interpretation of this "reserved" is that Etherboot may do whatever it
- likes, as long as its environment is kept intact (like the BIOS
- variables). Hopefully fixed rtl_poll() once and for all. The symptoms
- were that if Etherboot was left at the boot menu for several minutes, the
- first eth_poll failed. Seems like I am the only person who does this.
- First of all I fixed the debugging code and then set out for a long bug
- hunting session. It took me about a week full time work - poking around
- various places in the driver, reading Don Becker's and Jeff Garzik's Linux
- driver and even the FreeBSD driver (what a piece of crap!) - and
- eventually spotted the nasty thing: the transmit routine was acknowledging
- each and every interrupt pending, including the RxOverrun and RxFIFIOver
- interrupts. This confused the RTL8139 thoroughly. It destroyed the
- Rx ring contents by dumping the 2K FIFO contents right where we wanted to
- get the next packet. Oh well, what fun.
-
- 18 Jan 2000 mdc@thinguin.org (Marty Connor)
- Drastically simplified error handling. Basically, if any error
- in transmission or reception occurs, the card is reset.
- Also, pointed all transmit descriptors to the same buffer to
- save buffer space. This should decrease driver size and avoid
- corruption because of exceeding 32K during runtime.
-
- 28 Jul 1999 (Matthias Meixner - meixner@rbg.informatik.tu-darmstadt.de)
- rtl_poll was quite broken: it used the RxOK interrupt flag instead
- of the RxBufferEmpty flag which often resulted in very bad
- transmission performace - below 1kBytes/s.

-How I added the SIS900 card to Etherboot
-
-Author: Marty Connor (mdc@thinguin.org)
-
-Date: 25 Febrary 2001
-
-Description:
-
-This file is intended to help people who want to write an Etherboot
-driver or port another driver to Etherboot. It is a starting point.
-Perhaps someday I may write a more detailed description of writing an
-Etherboot driver. This text should help get people started, and
-studying sis900.[ch] should help show the basic structure and
-techniques involved in writing and Etherboot driver.
-
-***********************************************************************
-
-0. Back up all the files I need to modify:
-
-cd etherboot-4.7.20/src
-cp Makefile Makefile.orig
-cp config.c config.c.orig
-cp pci.h pci.h.orig
-cp NIC NIC.orig
-cp cards.h cards.h.orig
-
-1. Edit src/Makefile to add SIS900FLAGS to defines
-
-SIS900FLAGS= -DINCLUDE_SIS900
-
-2. edit src/pci.h to add PCI signatures for card
-
-#define PCI_VENDOR_ID_SIS 0x1039
-#define PCI_DEVICE_ID_SIS900 0x0900
-#define PCI_DEVICE_ID_SIS7016 0x7016
-
-3. Edit src/config.c to add the card to the card probe list
-
-#if defined(INCLUDE_NS8390) || defined(INCLUDE_EEPRO100) ||
- defined(INCLUDE_LANCE) || defined(INCLUDE_EPIC100) ||
- defined(INCLUDE_TULIP) || defined(INCLUDE_OTULIP) ||
- defined(INCLUDE_3C90X) || defined(INCLUDE_3C595) ||
- defined(INCLUDE_RTL8139) || defined(INCLUDE_VIA_RHINE) ||
- defined(INCLUDE_SIS900) || defined(INCLUDE_W89C840)
-
-... and ...
-
-#ifdef INCLUDE_SIS900
- { PCI_VENDOR_ID_SIS, PCI_DEVICE_ID_SIS900,
- "SIS900", 0, 0, 0, 0},
- { PCI_VENDOR_ID_SIS, PCI_DEVICE_ID_SIS7016,
- "SIS7016", 0, 0, 0, 0},
-#endif
-
-... and ...
-
-#ifdef INCLUDE_SIS900
- { "SIS900", sis900_probe, pci_ioaddrs },
-#endif
-
-4. Edit NIC to add sis900 and sis7016 to NIC list
-
-# SIS 900 and SIS 7016
-sis900 sis900 0x1039,0x0900
-sis7016 sis900 0x1039,0x7016
-
-5. Edit cards.h to add sis900 probe routine declaration
-
-#ifdef INCLUDE_SIS900
-extern struct nic *sis900_probe(struct nic *, unsigned short *
- PCI_ARG(struct pci_device *));
-#endif
-
-***********************************************************************
-
-At this point, you can begin creating your driver source file. See
-the "Writing and Etherboot Driver" section of the Etherboot
-documentation for some hints. See the skel.c file for a starting
-point. If there is a Linux driver for the card, you may be able to
-use that. Copy and learn from existing Etherboot drivers (this is GPL
-/ Open Source software!).
-
-Join the etherboot-developers and etherboot-users mailing lists
-(information is on etherboot.sourceforge.net) for information and
-assistance. We invite more developers to help improve Etherboot.
-
-Visit the http://etherboot.sourceforge.net, http://thinguin.org,
-http://rom-o-matic.net, and http://ltsp.org sites for information and
-assistance.

-/*
- * The Schneider & Koch (SK) G16 Network device driver is based
- * on the 'ni6510' driver from Michael Hipp which can be found at
- * ftp://sunsite.unc.edu/pub/Linux/system/Network/drivers/nidrivers.tar.gz

- * A. Cox (A.Cox@swansea.ac.uk)
- * M. Hipp (mhipp@student.uni-tuebingen.de)
- * R. Bolz (Schneider & Koch, Germany)
- *
- * See README.sk_g16 for details about limitations and bugs for the
- * current version.
- *
- * To Do:
- * - Support of SK_G8 and other SK Network Cards.
- * - Autoset memory mapped RAM. Check for free memory and then
- * configure RAM correctly.
- * - SK_close should really set card in to initial state.
- * - Test if IRQ 3 is not switched off. Use autoirq() functionality.
- * (as in /drivers/net/skeleton.c)
- * - Implement Multicast addressing. At minimum something like
- * in depca.c.
- * - Redo the statistics part.
- * - Try to find out if the board is in 8 Bit or 16 Bit slot.
- * If in 8 Bit mode don't use IRQ 11.
- * - (Try to make it slightly faster.)

- * SK_G16 RAM
- *
- * The components are memory mapped and can be set in a region from

- * The Network components are: dual ported RAM, Prom, I/O Reg, Status-,

- *
- * dual ported RAM: This is the only memory region which the LANCE chip
- * has access to. From the Lance it is addressed from 0x0000 to
- * 0x3fbf. The host accesses it normally.
- *
- * PROM: The PROM obtains the ETHERNET-MAC-Address. It is realised as a
- * 8-Bit PROM, this means only the 16 even addresses are used of the
- * 32 Byte Address region. Access to a odd address results in invalid
- * data.
- *
- * LANCE I/O Reg: The I/O Reg is build of 4 single Registers, Low-Byte Write,
- * Hi-Byte Write, Low-Byte Read, Hi-Byte Read.
- * Transfer from or to the LANCE is always in 16Bit so Low and High
- * registers are always relevant.
- *
- * The Data from the Readregister is not the data in the Writeregister!!
- *
- * Port: Status- and Controlregister.
- * Two different registers which share the same address, Status is
- * read-only, Control is write-only.
- *
- * I/O Command:
- * Any bitcombination written in here starts the transmission between
- * Host and LANCE.

- *
- * Change History
- *
- * Tigran Aivazian <tigran@sco.com>: TLan_PciProbe() now uses
- * new PCI BIOS interface.
- * Alan Cox <alan@redhat.com>: Fixed the out of memory
- * handling.
- *
- * Torben Mathiasen <torben.mathiasen@compaq.com> New Maintainer!
- *
- * v1.1 Dec 20, 1999 - Removed linux version checking
- * Patch from Tigran Aivazian.
- * - v1.1 includes Alan's SMP updates.
- * - We still have problems on SMP though,
- * but I'm looking into that.
- *
- * v1.2 Jan 02, 2000 - Hopefully fixed the SMP deadlock.
- * - Removed dependency of HZ being 100.
- * - We now allow higher priority timers to
- * overwrite timers like TLAN_TIMER_ACTIVITY
- * Patch from John Cagle <john.cagle@compaq.com>.
- * - Fixed a few compiler warnings.
- *
- * v1.3 Feb 04, 2000 - Fixed the remaining HZ issues.
- * - Removed call to pci_present().
- * - Removed SA_INTERRUPT flag from irq handler.
- * - Added __init and __initdata to reduce resisdent
- * code size.
- * - Driver now uses module_init/module_exit.
- * - Rewrote init_module and tlan_probe to
- * share a lot more code. We now use tlan_probe
- * with builtin and module driver.
- * - Driver ported to new net API.
- * - tlan.txt has been reworked to reflect current
- * driver (almost)
- * - Other minor stuff
- *
- * v1.4 Feb 10, 2000 - Updated with more changes required after Dave's
- * network cleanup in 2.3.43pre7 (Tigran & myself)
- * - Minor stuff.
- *
- * v1.5 March 22, 2000 - Fixed another timer bug that would hang the driver
- * if no cable/link were present.
- * - Cosmetic changes.
- * - TODO: Port completely to new PCI/DMA API
- * Auto-Neg fallback.
- *
- * v1.6 April 04, 2000 - Fixed driver support for kernel-parameters. Haven't
- * tested it though, as the kernel support is currently
- * broken (2.3.99p4p3).
- * - Updated tlan.txt accordingly.
- * - Adjusted minimum/maximum frame length.
- * - There is now a TLAN website up at
- * http://tlan.kernel.dk
- *
- * v1.7 April 07, 2000 - Started to implement custom ioctls. Driver now
- * reports PHY information when used with Donald
- * Beckers userspace MII diagnostics utility.
- *
- * v1.8 April 23, 2000 - Fixed support for forced speed/duplex settings.
- * - Added link information to Auto-Neg and forced
- * modes. When NIC operates with auto-neg the driver
- * will report Link speed & duplex modes as well as
- * link partner abilities. When forced link is used,
- * the driver will report status of the established
- * link.
- * Please read tlan.txt for additional information.
- * - Removed call to check_region(), and used
- * return value of request_region() instead.
- *
- * v1.8a May 28, 2000 - Minor updates.
- *
- * v1.9 July 25, 2000 - Fixed a few remaining Full-Duplex issues.
- * - Updated with timer fixes from Andrew Morton.
- * - Fixed module race in TLan_Open.
- * - Added routine to monitor PHY status.
- * - Added activity led support for Proliant devices.
- *
- * v1.10 Aug 30, 2000 - Added support for EISA based tlan controllers
- * like the Compaq NetFlex3/E.
- * - Rewrote tlan_probe to better handle multiple
- * bus probes. Probing and device setup is now
- * done through TLan_Probe and TLan_init_one. Actual
- * hardware probe is done with kernel API and
- * TLan_EisaProbe.
- * - Adjusted debug information for probing.
- * - Fixed bug that would cause general debug information
- * to be printed after driver removal.
- * - Added transmit timeout handling.
- * - Fixed OOM return values in tlan_probe.
- * - Fixed possible mem leak in tlan_exit
- * (now tlan_remove_one).
- * - Fixed timer bug in TLan_phyMonitor.
- * - This driver version is alpha quality, please
- * send me any bug issues you may encounter.
- *
- * v1.11 Aug 31, 2000 - Do not try to register irq 0 if no irq line was
- * set for EISA cards.
- * - Added support for NetFlex3/E with nibble-rate
- * 10Base-T PHY. This is untestet as I haven't got
- * one of these cards.
- * - Fixed timer being added twice.
- * - Disabled PhyMonitoring by default as this is
- * work in progress. Define MONITOR to enable it.
- * - Now we don't display link info with PHYs that
- * doesn't support it (level1).
- * - Incresed tx_timeout beacuse of auto-neg.
- * - Adjusted timers for forced speeds.
- *
- * v1.12 Oct 12, 2000 - Minor fixes (memleak, init, etc.)
- *
- * v1.13 Nov 28, 2000 - Stop flooding console with auto-neg issues
- * when link can't be established.
- * - Added the bbuf option as a kernel parameter.
- * - Fixed ioaddr probe bug.
- * - Fixed stupid deadlock with MII interrupts.
- * - Added support for speed/duplex selection with
- * multiple nics.
- * - Added partly fix for TX Channel lockup with
- * TLAN v1.0 silicon. This needs to be investigated
- * further.
- *
- * v1.14 Dec 16, 2000 - Added support for servicing multiple frames per.
- * interrupt. Thanks goes to
- * Adam Keys <adam@ti.com>
- * Denis Beaudoin <dbeaudoin@ti.com>
- * for providing the patch.
- * - Fixed auto-neg output when using multiple
- * adapters.
- * - Converted to use new taskq interface.
- *
- * v1.14a Jan 6, 2001 - Minor adjustments (spinlocks, etc.)
- *

-
- Based on Ken Yap's Tulip Etherboot Driver and Donald Becker's
- Linux Tulip Driver. Supports N-Way speed auto-configuration on
- MX98715, MX98715A and MX98725. Support inexpensive PCI 10/100 cards
- based on the Macronix MX987x5 chip, such as the SOHOware Fast
- model SFA110A, and the LinkSYS model LNE100TX. The NetGear
- model FA310X, based on the LC82C168 chip is supported.
- The TRENDnet TE100-PCIA NIC which uses a genuine Intel 21143-PD
- chipset is supported. Also, Davicom DM9102's.

-
-/*
- 11 Apr 2001 mdc [patch to etherboot 4.7.24]
- Major rewrite to include Linux tulip driver media detection
- code. This driver should support a lot more cards now.
- 16 Jul 2000 mdc 0.75b11
- Added support for ADMtek 0985 Centaur-P, a "Comet" tulip clone
- which is used on the LinkSYS LNE100TX v4.x cards. We already
- support LNE100TX v2.0 cards, which use a different controller.
- 04 Jul 2000 jam ?
- Added test of status after receiving a packet from the card.
- Also uncommented the tulip_disable routine. Stray packets
- seemed to be causing problems.
- 27 Apr 2000 njl ?
- 29 Feb 2000 mdc 0.75b7
- Increased reset delay to 3 seconds because Macronix cards seem to
- need more reset time before card comes back to a usable state.
- 26 Feb 2000 mdc 0.75b6
- Added a 1 second delay after initializing the transmitter because
- some cards seem to need the time or they drop the first packet
- transmitted.
- 23 Feb 2000 mdc 0.75b5
- removed udelay code and used currticks() for more reliable delay
- code in reset pause and sanity timeouts. Added function prototypes
- and TX debugging code.
- 21 Feb 2000 mdc patch to Etherboot 4.4.3
- Incorporated patches from Bob Edwards and Paul Mackerras of
- Linuxcare's OZLabs to deal with inefficiencies in tulip_transmit
- and udelay. We now wait for packet transmission to complete
- (or sanity timeout).
- 04 Feb 2000 Robert.Edwards@anu.edu.au patch to Etherboot 4.4.2
- patch to tulip.c that implements the automatic selection of the MII
- interface on cards using the Intel/DEC 21143 reference design, in
- particular, the TRENDnet TE100-PCIA NIC which uses a genuine Intel
- 21143-PD chipset.
- 11 Jan 2000 mdc 0.75b4
- Added support for NetGear FA310TX card based on the LC82C168
- chip. This should also support Lite-On LC82C168 boards.
- Added simple MII support. Re-arranged code to better modularize
- initializations.
- 04 Dec 1999 mdc 0.75b3
- Added preliminary support for LNE100TX PCI cards. Should work for
- PNIC2 cards. No MII support, but single interface (RJ45) tulip
- cards seem to not care.
- 03 Dec 1999 mdc 0.75b2
- Renamed from mx987x5 to tulip, merged in original tulip init code
- from tulip.c to support other tulip compatible cards.
- 02 Dec 1999 mdc 0.75b1
- Released Beta MX987x5 Driver for code review and testing to netboot
- and thinguin mailing lists.

-
-This is a tulip and clone driver for Etherboot. See the revision
-history in the tulip.c file for information on changes. This version
-of the driver incorporates changes from Bob Edwards and Paul Mackerras
-who cantributed changes to support the TRENDnet TE100-PCIA NIC which
-uses a genuine Intel 21143-PD chipset. There are also various code
-cleanups to make time-based activities more reliable.
-
-Of course you have to have all the usual Etherboot environment
-(bootp/dhcp/NFS) set up, and you need a Linux kernel with v0.91g
-(7.16.99) or later of the tulip.c driver compiled in to support some
-MX98715 based cards. That file is available at:
-
- http://cesdis.gsfc.nasa.gov/linux/drivers/test/tulip.c
-
-NOTES
-
-I've tested this driver with a SOHOware Fast 10/100 Model SDA110A,
-a Linksys LNE100TX v2.0, and a Netgear FA310TX card, and it worked at
-both 10 and 100 mbits. Other cards based on the tulip family may work as
-well.
-
-These cards are about 20$US, are supported by Linux and now Etherboot,
-and being PCI, they auto-configure IRQ and IOADDR and auto-negotiate
-10/100 half/full duplex. It seems like a pretty good value compared to
-some of the pricier cards, and can lower the cost of building/adapting
-thin client workstations substantially while giving a considerable
-performance increase.
-
-On some PCI tulip clone chipsets (MX987x5, LC82C115, LC82C168) this driver
-lets the card choose the fastest speed it can negotiate with the peer
-device. On other cards, it chooses 10mbit half-duplex.
-
-I burned an AM27C256 (32KByte) EPROM with mx987x5.lzrom and it worked.
-According to the data sheet the MX98715A supports up to 64K (27C512)
-EPROMs,
-
-I've liberally commented the code and header files in the hope that it
-will help the next person who hacks the code or needs to support some
-tulip clone card, or wishes to add functionality.
-
-Anyway, please test this if you can on your tulip based card, and let
-me (mdc@thinguin.org) and the netboot list (netboot@baghira.han.de)
-know how things go. I also would appreciate code review by people who
-program. I'm a strong believer in "another set of eyes".
-
-Regards,
-

- Theory of Operation
-
-I. Board Compatibility
-
-This driver is designed for the VIA 86c100A Rhine-II PCI Fast Ethernet
-controller.
-
-II. Board-specific settings
-
-Boards with this chip are functional only in a bus-master PCI slot.
-
-Many operational settings are loaded from the EEPROM to the Config word at
-offset 0x78. This driver assumes that they are correct.
-If this driver is compiled to use PCI memory space operations the EEPROM
-must be configured to enable memory ops.
-
-III. Driver operation
-
-IIIa. Ring buffers
-
-This driver uses two statically allocated fixed-size descriptor lists
-formed into rings by a branch from the final descriptor to the beginning of
-the list. The ring sizes are set at compile time by RX/TX_RING_SIZE.
-
-IIIb/c. Transmit/Receive Structure
-
-This driver attempts to use a zero-copy receive and transmit scheme.
-
-Alas, all data buffers are required to start on a 32 bit boundary, so
-the driver must often copy transmit packets into bounce buffers.
-
-The driver allocates full frame size skbuffs for the Rx ring buffers at
-open() time and passes the skb->data field to the chip as receive data
-buffers. When an incoming frame is less than RX_COPYBREAK bytes long,
-a fresh skbuff is allocated and the frame is copied to the new skbuff.
-When the incoming frame is larger, the skbuff is passed directly up the
-protocol stack. Buffers consumed this way are replaced by newly allocated
-skbuffs in the last phase of netdev_rx().
-
-The RX_COPYBREAK value is chosen to trade-off the memory wasted by
-using a full-sized skbuff for small frames vs. the copying costs of larger
-frames. New boards are typically used in generously configured machines
-and the underfilled buffers have negligible impact compared to the benefit of
-a single allocation size, so the default value of zero results in never
-copying packets. When copying is done, the cost is usually mitigated by using
-a combined copy/checksum routine. Copying also preloads the cache, which is
-most useful with small frames.
-
-Since the VIA chips are only able to transfer data to buffers on 32 bit
-boundaries, the the IP header at offset 14 in an ethernet frame isn't
-longword aligned for further processing. Copying these unaligned buffers
-has the beneficial effect of 16-byte aligning the IP header.
-
-IIId. Synchronization
-
-The driver runs as two independent, single-threaded flows of control. One
-is the send-packet routine, which enforces single-threaded use by the
-dev->tbusy flag. The other thread is the interrupt handler, which is single
-threaded by the hardware and interrupt handling software.
-
-The send packet thread has partial control over the Tx ring and 'dev->tbusy'
-flag. It sets the tbusy flag whenever it's queuing a Tx packet. If the next
-queue slot is empty, it clears the tbusy flag when finished otherwise it sets
-the 'lp->tx_full' flag.
-
-The interrupt handler has exclusive control over the Rx ring and records stats
-from the Tx ring. After reaping the stats, it marks the Tx queue entry as
-empty by incrementing the dirty_tx mark. Iff the 'lp->tx_full' flag is set, it
-clears both the tx_full and tbusy flags.
-
-IV. Notes
-
-IVb. References
-
-Preliminary VT86C100A manual from http://www.via.com.tw/

-http://cesdis.gsfc.nasa.gov/linux/misc/NWay.html
-
-IVc. Errata
-
-The VT86C100A manual is not reliable information.
-The chip does not handle unaligned transmit or receive buffers, resulting
-in significant performance degradation for bounce buffer copies on transmit
-and unaligned IP headers on receive.
-The chip does not pad to minimum transmit length.

- *
- * This is the etherboot driver for cards based on Winbond W89c840F chip.
- *
- * It was written from skeleton source, with Donald Becker's winbond-840.c
- * kernel driver as a guideline. Mostly the w89c840 related definitions
- * and the lower level routines have been cut-and-pasted into this source.
- *
- * Frankly speaking, about 90% of the code was obtained using cut'n'paste
- * sequence :) while the remainder appeared while brainstorming
- * Linux Kernel 2.4.0-testX source code. Thanks, Donald and Linus!
- *
- * There was a demand for using this card in a rather large
- * remote boot environment at MSKP OVTI Lab of
- * Moscow Institute for Physics and Technology (MIPT) -- http://www.mipt.ru/
- * so you may count that for motivation.

-
- A command-line consists of ``section''s. A section is a part of the
- line which may be displayed on the screen, but a section is never
- displayed with another section simultaneously.
-
- Each section is basically 77 or less characters, but the exception
- is the first section, which is 78 or less characters, because the
- starting point is special. See below.
-
- The first section contains a prompt and a command-line (or the
- first part of a command-line when it is too long to be fit in the
- screen). So, in the first section, the number of command-line

- * A directory consists of some number of blocks of DIRBLKSIZ

- * to disk in a single atomic operation (e.g. 512 bytes on most machines).
- *
- * Each DIRBLKSIZ byte block contains some number of directory entry
- * structures, which are of variable length. Each directory entry has
- * a struct direct at the front of it, containing its inode number,
- * the length of the entry, and the length of the name contained in
- * the entry. These are followed by the name padded to a 4 byte boundary
- * with null bytes. All names are guaranteed null terminated.
- * The maximum length of a name in a directory is MAXNAMLEN.
- *
- * The macro DIRSIZ(dp) gives the amount of space required to represent
- * a directory entry. Free space in a directory is represented by
- * entries which have dp->d_reclen > DIRSIZ(dp). All DIRBLKSIZ bytes
- * in a directory block are claimed by the directory entries. This
- * usually results in the last entry in a directory having a large
- * dp->d_reclen. When entries are deleted from a directory, the
- * space is returned to the previous entry in the same directory
- * block by increasing its dp->d_reclen. If the first entry of
- * a directory block is free, then its dp->d_ino is set to 0.

- Inflate deflated (PKZIP's method 8 compressed) data. The compression
- method searches for as much of the current string of bytes (up to a
- length of 258) in the previous 32K bytes. If it doesn't find any
- matches (of at least length 3), it codes the next byte. Otherwise, it
- codes the length of the matched string and its distance backwards from
- the current position. There is a single Huffman code that codes both
- single bytes (called "literals") and match lengths. A second Huffman
- code codes the distance information, which follows a length code. Each
- length or distance code actually represents a base value and a number
- of "extra" (sometimes zero) bits to get to add to the base value. At
- the end of each deflated block is a special end-of-block (EOB) literal/
- length code. The decoding process is basically: get a literal/length
- code; if EOB then done; if a literal, emit the decoded byte; if a
- length then get the distance and emit the referred-to bytes from the
- sliding window of previously emitted data.
-
- There are (currently) three kinds of inflate blocks: stored, fixed, and
- dynamic. The compressor deals with some chunk of data at a time, and
- decides which method to use on a chunk-by-chunk basis. A chunk might
- typically be 32K or 64K. If the chunk is uncompressible, then the
- "stored" method is used. In this case, the bytes are simply stored as
- is, eight bits per byte, with none of the above coding. The bytes are
- preceded by a count, since there is no longer an EOB code.
-
- If the data is compressible, then either the fixed or dynamic methods
- are used. In the dynamic method, the compressed data is preceded by
- an encoding of the literal/length and distance Huffman codes that are
- to be used to decode this block. The representation is itself Huffman
- coded, and so is preceded by a description of that code. These code
- descriptions take up a little space, and so for small blocks, there is
- a predefined set of codes, called the fixed codes. The fixed method is
- used if the block codes up smaller that way (usually for quite small
- chunks), otherwise the dynamic method is used. In the latter case, the
- codes are customized to the probabilities in the current block, and so
- can code it much better than the pre-determined fixed codes.
-
- The Huffman codes themselves are decoded using a mutli-level table
- lookup, in order to maximize the speed of decoding plus the speed of
- building the decoding tables. See the comments below that precede the
- lbits and dbits tuning parameters.
- */
-
-
-/*
- Notes beyond the 1.93a appnote.txt:
-
- 1. Distance pointers never point before the beginning of the output
- stream.
- 2. Distance pointers can point back across blocks, up to 32k away.
- 3. There is an implied maximum of 7 bits for the bit length table and
- 15 bits for the actual data.
- 4. If only one code exists, then it is encoded using one bit. (Zero
- would be more efficient, but perhaps a little confusing.) If two
- codes exist, they are coded using one bit each (0 and 1).
- 5. There is no way of sending zero distance codes--a dummy must be
- sent if there are none. (History: a pre 2.0 version of PKZIP would
- store blocks with no distance codes, but this was discovered to be
- too harsh a criterion.) Valid only for 1.93a. 2.04c does allow
- zero distance codes, which is sent as one code of zero bits in
- length.
- 6. There are up to 286 literal/length codes. Code 256 represents the
- end-of-block. Note however that the static length tree defines
- 288 codes just to fill out the Huffman codes. Codes 286 and 287
- cannot be used though, since there is no length base or extra bits
- defined for them. Similarly, there are up to 30 distance codes.
- However, static trees define 32 codes (all 5 bits) to fill out the
- Huffman codes, but the last two had better not show up in the data.
- 7. Unzip can check dynamic Huffman blocks for complete code sets.
- The exception is that a single code would not be complete (see #4).
- 8. The five bits following the block type is really the number of
- literal codes sent minus 257.
- 9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits
- (1+6+6). Therefore, to output three times the length, you output
- three codes (1+1+1), whereas to output four times the same length,
- you only need two codes (1+3). Hmm.
- 10. In the tree reconstruction algorithm, Code = Code + Increment
- only if BitLength(i) is not zero. (Pretty obvious.)
- 11. Correction: 4 Bits: # of Bit Length codes - 4 (4 - 19)
- 12. Note: length code 284 can represent 227-258, but length code 285
- really is 258. The last length deserves its own, short code
- since it gets used a lot in very redundant files. The length
- 258 is special since 258 - 3 (the min match length) is 255.
- 13. The literal/length and distance code bit lengths are read as a
- single stream of lengths. It is possible (and advantageous) for
- a repeat code (16, 17, or 18) to go across the boundary between
- the two sets of lengths.

- Huffman code decoding is performed using a multi-level table lookup.
- The fastest way to decode is to simply build a lookup table whose
- size is determined by the longest code. However, the time it takes
- to build this table can also be a factor if the data being decoded
- is not very long. The most common codes are necessarily the
- shortest codes, so those codes dominate the decoding time, and hence
- the speed. The idea is you can have a shorter table that decodes the
- shorter, more probable codes, and then point to subsidiary tables for
- the longer codes. The time it costs to decode the longer codes is
- then traded against the time it takes to make longer tables.
-
- This results of this trade are in the variables lbits and dbits
- below. lbits is the number of bits the first level table for literal/
- length codes can decode in one step, and dbits is the same thing for
- the distance codes. Subsequent tables are also less than or equal to
- those sizes. These values may be adjusted either when all of the
- codes are shorter than that, in which case the longest code length in
- bits is used, or when the shortest code is *longer* than the requested
- table size, in which case the length of the shortest code in bits is
- used.
-
- There are two different values for the two tables, since they code a
- different number of possibilities each. The literal/length table
- codes 286 possible values, or in a flat code, a little over eight
- bits. The distance table codes 30 possible values, or a little less
- than five bits, flat. The optimum values for speed end up being
- about one bit more than those, so lbits is 8+1 and dbits is 5+1.
- The optimum values may differ though from machine to machine, and
- possibly even between compilers. Your mileage may vary.

- where NEEDBITS makes sure that b has at least j bits in it, and
- DUMPBITS removes the bits from b. The macros use the variable k
- for the number of bits in b. Normally, b and k are register
- variables for speed, and are initialized at the beginning of a
- routine that uses these macros from a global bit buffer and count.
-
- If we assume that EOB will be the longest code, then we will never
- ask for bits with NEEDBITS that are beyond the end of the stream.
- So, NEEDBITS should not read any more bytes than are needed to
- meet the request. Then no bytes need to be "returned" to the buffer
- at the end of the last block.
-
- However, this assumption is not true for fixed blocks--the EOB code
- is 7 bits, but the other literal/length codes can be 8 or 9 bits.
- (The EOB code is shorter than other codes because fixed blocks are
- generally short. So, while a block always has an EOB, many other
- literal/length codes have a significantly lower probability of
- showing up at all.) However, by making the first table have a
- lookup of seven bits, the EOB code will be found in that first
- lookup, and so will not require that too many bits be pulled from

- *
- * Substitute the given parameters into the given string by the following
- * rules (taken from terminfo(5)):
- *
- * Cursor addressing and other strings requiring parame-
- * ters in the terminal are described by a parameterized string
- * capability, with like escapes %x in it. For example, to
- * address the cursor, the cup capability is given, using two
- * parameters: the row and column to address to. (Rows and
- * columns are numbered from zero and refer to the physical
- * screen visible to the user, not to any unseen memory.) If
- * the terminal has memory relative cursor addressing, that can
- * be indicated by
- *
- * The parameter mechanism uses a stack and special %
- * codes to manipulate it. Typically a sequence will push one
- * of the parameters onto the stack and then print it in some
- * format. Often more complex operations are necessary.
- *
- * The % encodings have the following meanings:
- *
- * %% outputs `%'
- * %c print pop() like %c in printf()
- * %s print pop() like %s in printf()
- * %[[:]flags][width[.precision]][doxXs]
- * as in printf, flags are [-+#] and space
- * The ':' is used to avoid making %+ or %-
- * patterns (see below).
- *
- * %p[1-9] push ith parm
- * %P[a-z] set dynamic variable [a-z] to pop()
- * %g[a-z] get dynamic variable [a-z] and push it
- * %P[A-Z] set static variable [A-Z] to pop()
- * %g[A-Z] get static variable [A-Z] and push it
- * %l push strlen(pop)
- * %'c' push char constant c
- * %{nn} push integer constant nn
- *
- * %+ %- %* %/ %m
- * arithmetic (%m is mod): push(pop() op pop())
- * %& %| %^ bit operations: push(pop() op pop())
- * %= %> %< logical operations: push(pop() op pop())
- * %A %O logical and & or operations for conditionals
- * %! %~ unary operations push(op pop())
- * %i add 1 to first two parms (for ANSI terminals)
- *
- * %? expr %t thenpart %e elsepart %;
- * if-then-else, %e elsepart is optional.
- * else-if's are possible ala Algol 68:
- * %? c1 %t b1 %e c2 %t b2 %e c3 %t b3 %e c4 %t b4 %e b5 %;
- *
- * For those of the above operators which are binary and not commutative,
- * the stack works in the usual way, with
- * %gx %gy %m
- * resulting in x mod y, not the reverse.

-Usage: $program [-hVF] [-t TYPE] [-d DIRECTORY] [-s FS_TYPE] -f TAR_FILE
-Make a Bootable IMAGE using GRUB as a bootloader
-
-Options:
- Actions:
- -d DIRECTORY [default CWD]
- Directory where the boot.image and the partition subdirectories
- are/will be created
- -f TAR_FILE
- Name of the tar file containing the filesystem to install. Can
- be a pure tar file [.tar] or a compressed tar file
- [.tar.gz|.tar.bz2]
- -s FS_TYPE
- Type of the file system to create on the virtual disk. Choices
- are:
- ext2 on GNU [default is ext2]
- ext2, minix or msdos on GNU/Linux [default is ext2]
-
- -t TYPE
- Type of the image to create. Choices are '1.20', '1.44', '1.60',
- '1.68', '1.74', '2.88' or 'hd' [default is hd]
- -F
- Force to set the set_dpt flag (unnecessary 99% of the time! Be
- careful!
