I have an old PC-class machine that I decided to add a hard card to (a Plus
10 meg hardcard).  I want to continue to use the original hard drive, a Xebec
9710H 10 meg drive and controller.  That's the problem -- the two drives/
controllers don't get along at all together.  With both plugged in the
machine refuses to even boot.  Since the power-on diagnostics run fine, this
is not a power problem.

I have a program that displays the "system I/O table".  It shows one spot only
for fixed disk, 320-32F.  Does this mean the PC can only have one controller?
That same table shows a lot of "extra" slots available (e.g. prototype cards,
ega alternates, etc.).  Can I get my controller to use one of these "slots"
instead?

That's another problem -- I don't have the docs for either drive!  (Both
were bought used).  The Xebec is the drive I want as drive 2 (i.e. drive
D).  The Xebec has four switches labelled "I/O", four labelled "OPTN"
(option?), one labelled "RD", and three labelled "ROM".  The only switches
on are "RD", and the two middle "I/O" switches.

Any comments or suggestions?
