First off, why is this in the drivers forum? Second, if it happens before the computer boots from the CD, it's likely a problem with your CD. winnt.sif doesn't get used until Windows setup actually starts after the computer is booted from the CD, and the RAID driver integration is at an even later stage. I'm almost 100% certain your problem lies elsewhere. Try the ISO in VirtualPC and see if it's bootable in there. If not, your ISO is obviously bad . If it works, then I'd say your boot CD was just bad.
