Paul, George Morgan and I (see I added him to the CC:, he's not
subscribed) are both seeing problems with inability to boot IBM Ultra 160
drives (he on a Adaptec 39160, me on a 29160).  Can you tell me where you
saw the stuff on this problem, so I can read up on it and see if there's
some sort of fix for us?

Thanks.
