One of my coworkers has an old IBM PC (not an XT) that he is trying to
add a hard card to.  At first the drive appeared to work OK, but then he
started seeing parity check errors.  Diagnostics showed random flakey
memory errors.  He replaced the power supply with a 150W unit.  The
power on self test now reports error number 131.  Diagnostics report the
same error.  The error persists even with the hard card out of the
system.  The system has 256K on the mother board.  The hard card has a
20Mb drive, but I don't have the brand handy.

It looks to me like the next step is to verify that the system works
without the hard card and with the original power supply, and then try
it with a different 150W supply and the hard card in.  My question for
the net is: Is there anything other than power that one needs to watch
out for when adding a hard card to a PC?  Has anyone out there had
similar problems?

If you have any suggestions, please e-mail directly to me.  I will
summarize if anything significant turns up.

Thanks
Paul
