If your board has an "old" revision of the 925x, you will not have any benefit from using another bios... But if the chip is actually an 925xe, the trick might work.

I'll try it myself tomorrow, I'll fash the bios in an external flash-programmer, so I will not have problems with the flashing itself...

Will post results later.

Anyone knows of a way of determining what kind of northbridge chip is on the board without takeing the cooler off???
And what bios should I use??? Latest beta or latest final?
