Hmm, well. First off, try disabling DMA for the hard drive and CD-ROM in the
BIOS. Secondly, you can hack on btx to add a while (1) loop ('foo: jmp foo')
and move it around to get it to stop looping after the first fault so you can
capture the details. I can help you with that if you aren't familiar with
x86 assembly. Once that is done, I can look at the fault details to try to
figure out what your BIOS is doing that is making the machine unhappy.
