It was the UX board as far as I know.

Since I wasn't the person trying to get things working on this board (it
was Stefan Esser <se@freebsd.org>), I don't know exactly what the firmware
looks like. According to Stefan, it had a completely different look and
feel from AlphaBIOS though.

I believe that Stefan contacted both Samsung and DeskStation to try to get
programming information with no luck. I think Samsung asked for an NDA and
I'm not sure if DeskStation even replied.  Stefan would know for sure;
since I don't think he reads this list, I have Cc'ed him.
