Herein lies the rub. dosdev == 0 means it's a floppy disk. boot.c
converts this into `maj = 2'. Only if the 0x80 flag is set, it will
move to maj = 0 (wd) or maj = 4 (sd).
If i read the code right, it looks as if your BIOS doesn't pass the
correct value in %dl down to the bootstrap. (It apparently passes
0 there as opposed to the boot drive BIOS ID.) Call it ``broken''...
Your only chance short of replacing the BIOS is to hack the bootcode
on your harddisk so it will never try booting off a floppy again.
