Sounds great.. maybe you have come across something. Yes, the CPU Disconnect function arrived in your BIOS in revision of 2003/03/27 "6.Adds"CPU Disconnect Function" to adjust C1 disconnects. The Chipset does not support C2 disconnect; thus, disable C2 function."
For me though.. Im on an ASUS A7N8X Deluxe v2 BIOS 1007. From what I can see the CPU Disconnect isnt even in the Uber BIOS 1007 for this ASUS that has been discussed.
