You need to build a new kernel to use this device, even if you want to
use a loadable module.
Apply the patch to a 2.2.x kernel:
# cd linux
# patch -p1 <smart2.patch
Then build a new kernel and turn on Compaq SMART2 Disk Array support.
Create device nodes for the diskarray device:
# mkdev.ida [ctlrs]
Where ctlrs is the number of controllers you have (defaults to 1 if not
specified).

Booting:

You'll need to use a modified lilo if you want to boot from a disk array.
Its simply a version of lilo with some code added to tell it how to
understand Compaq diskarray devices.
