That was my first suspicion. I tried running MemTest, but after a 1/2 day,
I
quit testing. At the time I stopped, I needed the computer for scanning
some
pages. It is the only box in the place that is hooked up to the scanner.

But, if it truly a RAM thing, why does the CCC backup I made of 10.4 OS
just
before I erased and reformatted the internal main drive not have any
problem
running the computer via external FireWire400? I may be wrong, but I just
cannot see why it would run for several days and left on all night under
Tiger without a freeze, while it seizes up moments after Leopard starts
up,
if it was faulty/loose RAM. I mean both drives access the same chips. What
might be some other culprits that you mention above that I might try to
examine?

BTW: I looked on the drive that has Leopard - running from my external
Tiger-driven drive mentioned above and there were no crash logs in the
main
Library. That sure points to a non-software issue, I would guess.

What was in Library > Logs:
 
CoreRAID.log

SingleSignOnTools.log

And a folder: DirectoryService > DirectoryService.server.log

I would be glad to let you have a look if you think it would be
beneficial.
