A big thank you goes to Chris Mullendore and Chris Peck for helping me
out (independently) with my hard disk problem.  (mull@bigbird.hri.com and 
chris@zork.cc.binghamton.edu, respectively)

Apparently, to use an eight-bit hard disk controller in a 16-bit machine,
one needs to fake out the machine's BIOS since the hard disk controller 
has its own BIOS.  Specifically, when configuring the machine, don't tell it
about the hard drive.  Specify 'No Hard Drive' instead.

Worked like a charm, although I still lost a 25 cent bet with my roommate
that I could get the new computer up within half an hour!

Thanks again to Chris & Chris!
Eric
