The 2.4.x kernel has two options for the HPT370 RAID chip(set) as found on
some motherboards .
The first recognizes it (always a good start) and lets you use it as
another pair of IDE channels. The second allows you to use the software
RAID features.
I use the first of these to get 4 master IDE channels (so HDD,HDD,DVD,CDRW
each on its own channel)
How good/stable the software raid option is I don't know.
Have fun,
