Don't forget: The floppy probe fails with most Compaq computers. Using the
scheme above would probably fail on Compaqs without CD-ROM support.
This problem seems quite tricky to solve. But if BIOS reports wrong
values, I consider this as a BIOS-bug. Has this been observed even for new
computers? I prefer stick with BIOS-detection, and maybe fix a workaround
for those sitting with old PS2-machines.
