Oxford 934 as 2 drive controller

[pqrst]

Hi there... I've got an enclosure using a oxford 934 chip bridgeboard (2 sata drive/fw800/fw400/usb ports). I'd like to temporarily connect up two bare sata drives and use them as separate drives like a normal controller but there doesn't seem to be a jumper setting for that. The jumper settings appear to be only JBoD, Raid 0, spanning and raid 1. Am missing something, or do I need to look for another controller board? Thanks in advance.
