Not sure it would load the preboot image in that configuration but you can give it a try.
That did it! Even though the boot.plist has GraphicsEnabler=Yes, setting it again on the chameleon boot screen fixed it. Thank you.
Yes, the preboot.dmg does not get loaded. I am going to try booting with the USB and then pointing to the hard drive partition with the install image. I will report back later.
I am running into a sleep issue, or more precisely a wake from sleep issue.
I successfully flashed the bios on my P8P67 Pro using your files for the Rev 3.0. I am using a GTX 460 with two displays connected via DVI. I have removed NullCPUPower Management and rebuilt kexts. On ML DP2, system goes to sleep and wakes up like a charm each time without any problems! However, on Lion (10.7.3) it does not always work. Most of the time only the primary display wakes up and the secondary display does not leaving the system in an unusable state and requiring a hard reset. I say most of the time only because on a couple of rare occasions both monitors initialized back after sleep. Is there anything different I should be doing in Lion? Thank you.
Sleep now works perfectly on my P8P67 Pro machine with modded bios, dual DVI displays on GTX 460, no NULLCPUpowermanagement, and running Lion (as well as ML Dp2). On Lion, I removed the Nvidia update for 10.7.3 from ###### (MacMan patch) and instead installed the Quadro drivers for Lion from the Nvidia web site. On ML, sleep works natively without any added nvidia kexts.
