Ah, here's the letter I got back from GVP! (2 weeks response time for a
faxed question, since they don't offer online voice support – it's that
sorta support that I always appreciated from GVP! :^)
They claim:
'The A4000-040 board requires a revision 7 RAMSEY chip for proper SCSI
operation on the A3000. In addition you may have to alter your MaxTransfer
values in the RDB of the drives. Try setting the value at "0xFE00".'
I tried setting the value on the single 50MB stock Quantum drive that is
on that machine, and it didn't seem to make a difference. FWIW, I've only
seen it lock up when 2 tasks access the drive simultaneously. I can fairly
reliably use it, as long as the demand on the SCIS I/O is fairly low….
When I run SCRAMmer on the A3000, it claims the RAMSEY is a 'Normal' Type,
and has a Code # of '0d' (which would be 13 if it's in Hex.) I've checked
the docs, and can't tell what the info is supposed to tell me. Oh well,
next time I pop the case I've got to remember to check the RAMSEY itself.
(Forgot to last time! :^)
Hope this helps your situation…..
