No matter what flags I use, I can't get the 4440s to boot to the installer. Always hangs on IOBluetoothHCIController Start Completed (sometimes hangs on mac framework successfully initialized.) I reset the bios. Changed the value you mentioned. Used the boot flags and tried a variety of others. I'm using 10.8.0 on a 4440s with a SANDY bridge i3 processor (That was working fine on my g770) Using unibeast 1.7.0 and don't want to download 10.8.3 installer right now because with my internet connection it would take 5 hours. So I'm using the 10.8.0 saved in my apps folder on the other laptop.
