In GRUB 2 we have: 2005-03-18 Yoshinori K. Okuji * fs/fat.c (grub_fat_mount): Ignore the 3rd bit of a media descriptor. This is ported from GRUB Legacy. but I couldn't find this one from GRUB Legacy: 2005-02-15 Yoshinori K. Okuji * stage2/builtins.c (install_func): If DEST_DRIVE is a hard disk, enable the workaround in Stage 1 by replacing the jmp with double nop's. * stage1/stage1.h (STAGE1_BOOT_DRIVE_CHECK): New macro. (STAGE1_BOOT_DRIVE_MASK): Removed. * stage1/stage1.S (boot_drive_check): New label. This implements a different workaround for buggy BIOSes which don't pass boot drive correctly. This is effective for BIOSes which pass a value without the seventh bit (0x80). (boot_drive_mask): Removed. As for other changes, I can't find them. Did you have anything else in mind when you mentioned these workarounds? -- Robert Millan I know my rights; I want my phone call! What use is a phone call, if you are unable to speak? (as seen on /.)
