boot dos and execute 'a:\b hd!0'.
this will show if b.com has the same problem (it won't touch the hard disc if
it detects there's a floppy installed). also, b.com has a debugging print installed
for this case.

it may be something like the cmos indicates there is a hard disc but the disc/controller
is in some sleep mode we don't know how to get out of.
