Actually, I think there are 2 problems that have been discussed -- the
disk corruption and a general instability resulting in oops'es at
various points shortly after boot up.

My memory system jas been set up very conservitavely and has been
rock solid in my other board (ka7), so I doubt it's that, but I
sure am happy to try a few more cominations of bios settings. Anything
I should look for in particular?

Thanks,
Seth
