I purchased a Compaq Deskpro 286-12 at the Cary Hamfest last week
and I could use a little information.  I bought this machine "as is"
with no documentation and not much idea of what was inside of it (I
did see it boot before paying for it, though).  I have several
questions about the machine and the various boards I have found
therein.  If you could help out, either with documentation you don't
need any more, answers to specific questions, pointers to more
appropriate news groups, etc. I'd appreciate it.

The biggest problem I'm having right now is with its extended memory
(XMS).  I installed DOS 5.0 with HIMEM.SYS and DOS=HIGH in the
config.sys file (standard installation created the file).  With this
setup, the machine locks up with a "Parity check 2 ??????" message
when accessing most, but not all, floppies.  Also, when I tried to
install MS Windows 3.1, it locked up with the same message when
running the SETUP program.  Removing the DOS=HIGH problem fixed the
floppy crash; removing HIMEM and DOS=HIGH caused Windows SETUP to
lock up (same msg) when it tried to "install the XMS driver".  Therefore
I think I'm having trouble with the extended memory.  I have tried
various combinations of the /cpuclock and /machine options on HIMEM.SYS
to no avail.

Machine setup:

   Compaq Deskpro 286-12 with 640K on the motherboard (I think)
   AST 286 Sixpack with 2 1M SIMMS
   Northern Telecom modem of unknown baud rate
   3Com EtherLink II card
   Floppy/Serial/Parallel/Winchester card (probably Compaq brand)
   VGA card of unknown brand (has a Paradise VGA chip) + mono monitor

I have some more specific information, model numbers, switch settings,
etc., at home for each of these.  If you think you can help me figure
out any of this equipment, drop me a line.  Thanks.

P.S.: I also got an HP LaserJet II printer.  If you have any doc on this
machine that you don't need anymore, I could use that too.
