The dmesg is from the Ubuntu install (I forgot to specify that -- my 
bad), and it would HAVE to see the drives -- it's booting from one of 
them.  I just don't understand why it's calling the CD-ROM a SCSI drive 
when it's actually an IDE, and the hard drives are referred-to as PATA 
when they're SCSI's!!!

The partition layout is from the default Ubuntu settings.

So the question is, what kind of driver comes on the OpenSUSE or 
Scientific Linux DVDs (or is there one that I can download from 
somewhere?), and what command I need to give them (when they boot from 
the DVD) to get them to see the SCSI drives ...
