RAID Devices show up as /dev/md/c#d#p#, where # is replaced by a device number
from 0 up.  So a RAID drive on the first controller with only one partition
would be /dev/md/c0d0p0.

I'm using a Mylex RAID DAC1100 controller card (have two DAC960's that can't be
used).  The 960's are need a hardware upgrade to allow them to have the v3.0 or
better bios installed (currently running 2.73 which is a single chip bios, 3.0+
is a two chip bios).
