The low end Promise & Highpoint RAID controllers *are* software RAID,
they have some smarts in their firmware which patch the BIOS to let the
machine see the array when called through BIOS calls (eg, DOS). If you
have a look at the source code for these devices, you'll see that all
the smarts are in the drivers.
