+
+ * stage2/char_io.c [!GRUB_UTIL] (memcpy): New function. It is
+ defined as an alias of grub_memmove. This is copied from GRUB 2.
+
+ * stage2/disk_io.c (print_completions): Simplified conditionals
+ to make it easier to edit the file with Emacs.
+ Added support for (cd).
+ (set_device): Likewise.

+ Change the type of BUFADDR from int to char *.
+ Use a virtual track to make sure that one track fits in the
+ buffer.
+ (sane_partition): Allow CURRENT_DRIVE to be CDROM_DRIVE, because
+ a bios drive for a CD-ROM is often assigned to greater than
+ 0x88.
+ (set_device): Use GRUB_INVALID_DRIVE instead of 0xFF.
+ (setup_part): Likewise.
+
+ * stage2/cmdline.c (init_cmdline): Use GRUB_INVALID_DRIVE.

+ equal to 0x88 or the drive supports LBA.
+ Set the sector size to SECTOR_SIZE if it is not a CD-ROM.
+
+ * stage2/asm.S (biosdisk_int13_extensions): Take a word
+ argument AX instead of a byte argument AH.

+
+ * configure.ac (--disable-iso9660): New option.
+2004-03-13 Yoshinori K. Okuji <okuji@enbug.org>
+
From Daniele Zelante <zeldan@email.it>:
* stage2/asm.S (stop_floppy): Use INT 13, AH=00h to stop the
floppy controller instead of a direct I/O.
`--disable-xfs'
Omit the XFS support in Stage 2.
+`--disable-iso9660'
+ Omit the ISO9660 support in Stage 2.
+
`--disable-gunzip'
Omit the decompression support in Stage 2.
* Add support for ReiserFS 3.
* Fix support for FreeBSD 5.
* Support ATARAID for Linux in the grub shell and grub-install.
+* Add CDROM support for El Torito with no emulation mode. You can use
+ (cd) as a CDROM drive in the config file.
New in 0.94 - 2004-01-25:
* Support building on x86-64 with gcc -m32.
