Hi.
If you are inclined to stay with SuSE, you can download openSuSE for free at
Software.openSUSE.org
I installed it recently in a virtual machine of VMware. The virtual disk supplied by VMware is a simulated SCSI, so at least some SCSI drivers are available out-of-the-box in openSuSE 10.3.
There are probably a number of other distributions you can use as well, and most of them are free. See
DistroWatch.com: Put the fun back into computing. Use Linux, BSD. for descriptions of many of them.
Best wishes ... cheers, drl
