Although I find this unlikely on an HP computer, it's possible that you'd need to install a 3rd party SCSI/RAID driver (also some ATA/100 controllers).  That can really foul you up.  I know that on my ASUS A7V with Promise ATA/100 controller I had to install 3rd party drivers to get win2k install to work right, on the CUSL2-C I didn't, and I didn't for either for WinXP.
