Rather an initrd under Linux. Note that there is a partial source
driver, and RH driver's disks here: (look under raid IC with the right
chipset for partial source.)

If you are doing raid 1. Lilo should work. It doesn't really matter
if lilo isn't aware of of the data on the other drive. Each has a full
copy of everything.
PS- Newer linux kernels should be able to support the "raid" controller
as a normal ide controller. You could then just configure linux
