Just speculating about what can be done using the dual bios capability of this board.

I have flashed to 0403, I guess I can go in there (the bios) and change the bios chip that I boot from. Then flash that to 0404, have a play with that, then if I don't like it just go back in there and change back to boot from the 0403 bios chip which already has my good settings preserved.

Can anyone confirm this is possible ?.
