My PWS433a can't boot off its 2940UW.  So, I just netboot it
with a kernel that looks for the root partition at sd0a.  My AS200
boots off a 100MB SCSI disk internally, and uses the 5 external
barracudas to run (and serves the boot image to the PWS433a.)
Are you absolutely sure that you can't fit a little SCSI disk
in there?  How about from an old Mac Laptop, didn't they have
little SCSI disks in them?
