I see that you have successfully modded the bios of an Asus P8P67 Pro motherboard into a SLIC 2.1 bios.
I have a similar BUT DIFFERENT BIOS motherboard, I have the Asus P8p67 (vanilla or plain) motherboard.
The bios has the same number (1204) as the Pro, but it is a DIFFERENT bios. So please use the linked bios and r/w.
It uses an UEFI BIOS based on AMI. An ASUS SLIC 2.1 is preferred of course.
I would rather try this route as loader bios' have been implicated in the problems with the P8P67 lockups from sleep mode.
I am running Windows 7 SP1 64 bit if it matters.
If you would be so kind I the bios 1204 and R/W are enclosed at:http://www.mediafire.com/?4ra0ij81q69117v
I am new to this forum but would greatly appreciate it!
