Hee, hee... yes, for now I boot from floppy first, then mount /dev/sda1
as root filesystem. I, of course, want to get rid of the floppy. My
motherboard is Mercury PVCLE266M-L with VIA C3 Samuel 2 cpu integrated
on the board. It has tons of boot device options, and detects my USB
key (SanDisk Cruzer Mini 256MB) as "USB RMD-FDD" and not as some kind of
harddisk. I think that's the problem: motherboard thinks it's floppy,
and LILO thinks it's SCSI harddisk (/dev/sda).
