 We couldn't boot from the scsi drives at all, I don't think it could see
them either (but that was a while ago). This was a while ago though (YDL
1.2.1), and we haven't had the need to try again. This was back in the day
when I had to boot into open firmware and set the boot-device manually
/pci@f2000000/foo/bar/ATTOExpressPCIPro/etc.... no fun.

 I did take the one UL3D card that we opened (and couldn't return) and
stick it in a Dell box running Mandrake - similar problems, but even more
headache. I've never had good experiences with Intel machines and SCSI. I
hope by IBM experiences won't be this way.

Cheers,

Chris
