   6 Hi Philip.  Below is the SLES 11 patch that disables 5785 support and
   7 forces the 57780 to use the in-driver phy code rather than the phylib
   8 code.
   9
  10 While I have your attention, are there any outstanding bootloader
  11 install bugs?  On my lab machine, I install SLES 11 onto partition 12
  12 and tell the installer to install the bootloader (GRUB) into the MBR
  13 of that partition.  I then reboot the machine and instruct the existing
  14 bootloader in partition 1 (GRUB again) to chainload to partition 12.
  15
  16 It seems the SLES 11 installer somehow corrupts the MBR of the disk so
  17 that it no longer boots.  I've installed SLES 11 twice now and on the
  18 2nd install, I carefully navigated through the bootloader configuration
  19 portion.  I don't think I'm doing anything wrong.  Anyways, just an FYI...
