[rescue] What disk in an Ultra5

[JJ Streicher-Bremer]

?
I have an Ultra5 that I'm going to bring back online.  It has the original 8
Gb drive in it right now.  As I recall I was able to put another drive on the
secondary controller to get more disk space, but was never able to boot off of
anything but that original 8 Gb drive.  Since that drive is getting a bit old
(and is still on the small side) I was wondering what disks I can use to boot
from in my ultra5.  Does anybody know?

Thanks in advance!
