I know the people there very well (have bought a lot from them), so I'll have to talk to them later this week if things doesnt work out.

First I tried the bios that came with the board. Then I flashed to 0504. That didnt help, so I tried 0612. That didn't help either, so I'm kind of hoping for a new bios. But the last one was released only a couple of weeks ago, so my expectations are low:-(

Hopeless that there is are so many problems with this board...
