This RAID controler requires a software RAID implementation.  We do
support the necessicary RAID functionality, but apparently we don't
support the meta data used by your BIOS.  All your average onboard RAID
system does is allow you to boot from a mirror or strip.  Once you're
booted, it's up to the OS to read the geometry data from the disks and
proceed with software RAID support.  Since there's no standard for the
on-disk metadata, we only support those systems were we've managed to
pry the data out of the manufacture or reverse engineer the format.
