Okuji * stage2/fsys_fat.c (fat_mount): Ignore the 3rd bit of a media descriptor, because some BIOSes overwrite this value, according to the storage mode (e.g. USB Floppy or USB HDD). [...] 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. -- Robert Millan I know my rights; I want my phone call!
