I have just changed my cpu from xp 2200 to xp 2600 and my system is only registering it as an xp 2000, I know I have to change the bios. The clock speed at present is 133, I think this is correct and or it might be 166. I know I have to change the ratio to 16x but I can't find how to change this setting anywhere in the bios. Any help would be much appriciated. Cheers rangersmith.
