Thanks for the tips. I have a full fresh 5.3 install with all my tweaks and
personality installed on the scsi. I am dumping to tape tonight.
What I might do is toss 2 IDE drives in there...do an install (mini) on the
1...get it up and running and then run /stand/sysinstall on the 2nd drive
and set it up, format it and then mount it. Then I can restore from tape
onto the 2nd drive too.
I did that last year when I lost a hard drive :)
