Hi Ian & Ed,

Thanks to you both for the great suggestions.  I think the easiest path 
for me to follow is to start with the software and conflict suggestions. 
AICU160.add should be up to date as I am running ecs 1.2 but I will 
double check and at least use a fresh copy from the cd. I didn't know 
that there was a newer SMP kernel than what I am running.  Will be sure 
to get it.

On the hardware side I was sure that disabling the onboard scsi and 
putting in a scsi card would solve my problem but it only took 10 
minutes to be proved wrong.  Since I rebooted I have been running it for 
about 2 hours with no problems, go figure.

Changing the cable makes sense as it (and ram) are the commen factors 
bewteen the onboard and scsi card.  I must say I can't answer the 
termination question.  The machine was used and when I turned it on the 
scsi was enabled so I never considered it.  I'm quite rusty on scsi 
matters so how do I tell?  I have a harddrive and tape drive internally 
and nothing externally.  If I remember right termination is turned on in 
the scsi bios?

Thanks again for your help.

Regards, Jim
