I have one of these at home, I'll look at it there. I think they follow the standard 3 jumper SCSI ID selection, so its just a matter of determining which side is the left and right.
If you dont want to wait, you could try installing the card with one of the end jumpers (10 or 12) closed, dont hook the drives up, boot the computer, and see what ID you have. Depending on whether you end up with ID 1 or 4, you'll know the order.
