Does it have an lc53c8xx chip? Then it'll probably work. But I seem to recall that only Symbios and one other manufacturer make boards with that chip, and that Adaptec isn't it...
For me, UBoot was too dumb to spin up hard drives correctly, so I couldn't boot from it. Linux would spin up the drives and then OS4 could use them after a reboot, but a cold start was unsuccessful. Didn't work with my scanner either, though this was in the Update 3 days, I think.
