Yeah, but I can't remember exactly how...
I believe I changed the boot order in Bios. I know that I never got the drive recognized from a dos prompt, and I know it wouldn't boot selecting boot from SCSI in the Bios. But I believe I simply changed the boot order to 'Just plain boot from CD 1st' and put the WinXP disk in (it's bootable).
HTH, I maybe wrong but give it a try...
