My spare PCIe board is the same GF 8400 as onboard graphics... So I got pretty much the same results with it last night
Do I understand it right that I need Natit to enable GF 8400 and _OverrideNV* kext would take care of onboard graphics? In other words if I just add Natit, it should fix my PCIe GF 8400 board and I really need _OverrideNV for onboard only?
BTW, what PolicyTymcedStreamDisabler.kext does exactly?
I suggest to use archivio.zip (latest) and the appleacpiplatform modded from #####
The override kexts in the archivio.zip solve the black screen at boot.
AppleACPIPlatform I need to just roll it back to 10.8.1, right? And to avoid CMOS reset I just need ElliottForceLegacyRTC and that's all I really need from #####, right?
