That's how it was done with W2K, but I assumed it had to be done that
way only because the HPT372 was created after W2K was developed.

I would have if I could have found any such thing. What I found was a
source archive, but its use presumes a working system on which the
driver could be compiled. I don't know how to compile drivers, nor do I
have a working Linux system of the type I would be installing on the
RAID equipped motherboard. All mine are older distros on older hardware
with no RAID.

After so long since release of the HPT372 (and other types of
motherboard "RAID"), I would have expected by now that the required
driver module would be on the newer distros' CDs, ready to add to the
installer's kernel line.

Thanks for the help. This subject is poorly covered anywhere, regardless
of distro.
