I did this a long time ago on my BX6 which made the default voltage 2.3v. I need to get it back too 2.0 again so I can install PIII chip, without worring about it going back it too 2.3 when installing a new chip. All i remember is you have to flash the bios ad leave it at the voltage you want and flash it the reset the bios...there some trick, i forgot it. Help me out please?
