Ok, I've got the Abit IC7-G, no BIOS changes or anything. it works with a temporary 533mhz pentium 4 2.4ghz, but not with my 800mhz pentium 4 2.4C. Any idea? BIOS update maybe? By not working, I mean with the 2.ghz the POST locks up after reading out the Hyper Threading Is Enabled, even after resetting CMOS.
