Well, both the HPT270 and the Promise Fasttrak "RAID" gimmicks are
SW in the BIOS, so there is no HW to support. You could use vinum
to get the exact same behavior...

He, I've got a patch submitted that should work with the promise
ie it does the RAID stuff in the driver and reads the RAID setup
from the BIOS/disks. I've yet to find out how/where HPT stores
their info, but in case I find out, I will probably add support
for these "BIOS RAID" setups...
