Hi Derek, 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, http://www.freebsd.org/cgi/man.cgi?query=ahd&sektion=4&manpath=FreeBSD+7.0-RELEASE 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.
