I am putting together a new system and have just installed the Rev2 m/b. Before loading Windows, I decided to update to the latest BIOS to see if I could get them to recognise my Athlon XP+ 2500 (Barton). But no such luck. I had to manually configure the settings to show 166fsb to get the correct processor speed of 1826mhz. Is this the correct procedure - or should the latest BIOS have adjusted the settings automatically? Thanks
