  1. easier bios tweaking etc...
    One of the bios' should be write protected, a failsafe backup ready to go if you brick the other one. There's a little switch to choose the bios that gets loaded, so if you brick the other one with bad update or tweak, just flip the switch, reboot and once it's running again flip it back and flash the writable bios again.
  2. thanks for the info but where can I find that switch?

    it should be near the crossfire fingers, at least it is there on the amd ref design.
