As mentioned in my post, I have configured the Adaptec BIOS
(SCSIselect/HostRAID) to create a RAID0 array.
The GENERIC Kernel natively-uses the 'ahd' adapter for this card,
dmesg does not post any errors, it recognised the card as ahd0, and
states that da0 & da1 are on that bus. I can not post the dmesg as the
NIC adapter needs to be patched once the OS is installed. I could find a
USB key and copy it over if you like, but there are no errors to consider.
