It sounds like this could well be the problem, although my system does
work fine with 2.0.33 SMP. Another person suggested I increase the
reset time (fairly easy to do) and see if giving the controller a bit
more time between the reset and the probe helps. I'm going to try this
first, since it won't take long. I looked for quite a while yesterday
for Adaptec BIOS upgrades, but it looks like you have to talk to a
technical rep (yuk!) to get one; the SuperMicro bios upgrades are even
more confusing, since they don't indicate what Adaptec bios version they
encapsulate (or if they encapsulate one at all or it is loaded
directly). Again, I'll have to deal with silly humans to go this route
(not to mention boot up in Evil Dos to run the update) so I'll put it
off as long as I can.
BTW, I really appreciate the suggestions.
