More SCSI timeout problems
Still trying to debug this situation with my AHA-2940 timing out.
Background on this is I took my Intel Zappa Motherboard with the
Pentium-90 out of the box, and put in this new mystery motherboard
made by "eurone" with 200MHz Cyrix MMX cpu, and now during long
file transfer operations, I get timeouts and SCSI resets.
Everyone suggested I check my termination and cabling, (which was not
changed when the new motherboard was put in) and I didn't see anything
out of whack. Just in case I put in a SCSI cable with only 2 connectors,
one end in the AHA-2940 and the other in a terminated hard drive. Lo
and behold if I try to transfer large ( > 1 or 2 megs) files, the
timeouts occur. Here are the error messages:

At this point I believe there must be some fundamental incompatibility
between the
2940 and this motherboard.
Should I run out and buy something different? This is getting expensive
!! Is anyone
using a 2940 with a ASUS SP 97 board successfully? I as because they are
available here
for around $350 with 200MHZ Intel Pentium.
I would appreciate any reports and/or suggestions on how to get back on
the air here.
Thanks!
