Did you ever get the bios modded? I got the same board but couldn't find anyone who modded the bios successfully.
Shoot, I forgot to quote it. It was the Intel DG43GT but I found out that I just use the intel OEM tool and it got it working after playing with it. Do you happen to have the Asus P8P67 standard modded bios? There was a link earlier in the thread but the download link is down. I think you modded the file a while back.
