mine didnt boot after one flash. it kind of did, but it was a boot loop. couldnt enter the bios either.
i will be moving to the latest bios tomorrow, so ill see how it goes.
tested with the ssdt and similar minimalistic boot.plist as yours, and only get 16 in msrdumper, so i want to see if the latest bios changes things.
btw, is your onboard audio working after the bios update?
working as in just using applehda rollback + alc8xxhda or toledas kext (not using hdaenabler)?
seen a couple posts by people on 3k roms with p67 boards saying their audio doesnt work anymore
