FreeBSD will use a hardware RAID device -only- if the particular type of RAID chip/chipset/controller is known to the included device drivers. >From some casual searching on the 'net, I can't find anything that indicates -what- RAID controller is in the Optiplex 755. IF you know, or can find that info, check: <http://www.freebsd.org/releases/9.0R/hardware.html#DISK>; to see if that disk controller is listed. If yes, it should 'just work'. If it is not listed, you're out of luck. If you can't in the controller informtion, you'll need to post something that includes the boot-up messages showing what FreeBSD found for disks and disk controllers.
