Thanks Jim but I don't think that's the problem.

Before replacing the motherboard this was a bootable RAID 0 volume. I
had already installed XP using the RAID driver from floppy.

My hope was that the RAID volume would simply be recognized and
everything would just work. Failing that I was hoping that there might
be some BIOS level utility that would allow me to reconstruct the RAID
volume information.

I have the same board not running raid but I think I read that you have to
load drivers for the raid. I will check later if and when I can find my
manual.

I had a P4P800 SE motherboard go bad. The POST wouldn't run. However
the CPU and video card both worked in another machine.

I've replaced this motherboard with another P4P800 SE. When I
configure it for RAID in the BIOS and I run the RAID setup Ctrl-I it
seems to recognize the existing RAID volume.

The problem is that it won't boot from the RAID array.

I guess I'm wondering how I go about getting this to work.

Thanks,
Brad
