        Add a workaround for buggy BIOSes which don't pass boot drive
        correctly. The idea is that GRUB forces the fixed disk flag
        when booted from a hard disk. When BIOS loads GRUB directly,
        the boot drive must be either of 0x00 and 0x80, so this should
        work, if those BIOSes always pass zero to %dl. AFAIK, this
        assumption is always correct.
        
        * stage2/builtins.c (install_func): Store the fixed disk flag of
        the destination drive in BOOT_DRIVE_MASK in Stage 1.
        
        * stage1/stage1.h (STAGE1_BOOT_DRIVE_MASK): New macro.
        
        * stage1/stage1.S (boot_drive_mask): New variable. It is or'ed
        to %dl.
