I ended up calling Digital Support on this. It turns out that there was a known problem with the revision of
our video card and some SCSI devices. Our ZLXP-E1 rev D. video card was replaced with a rev E card and the
video now works fine.
Thanks to the person who did reply to my original plea for help.
