Asus GTX 580 Mountain Lion 10.8.1 - Not natively working

06 September 2012 - 06:05 PM

Ok, I've tried so hard on my own and come up short, so now I need to ask for help. I've hackintoshed many a system, but this one is driving me nuts for the past 4 or 5 days and i'm about to give up.

I have the Asus P8Z77-I Deluxe motherboard, and have followed a good guide to get fully up and booted. I have upgraded my bios to the one at the Asus Modified bios repository to try and fix powermanagment. In my case, it didn't seem to work, so I just had to use nullcpu to get booting otherwise I get a kernel panic. No biggy. This bios doesn't seem to have done anything actually, as my issue below is no different either before or after flashing to it.

Everyone keeps saying that the GTX 580 is natively supported, but mine isn't working properly under Mountain Lion. I can get booted up, but with the default drivers, only with 1024X768 resolution and only in safemode. FYI, my graphics were working perfectly in Lion 10.7.3 with modified kexts injected with my device ID. The new drivers in Mountain Lion have my device ID in it by default, and still aren't working. Actually, with the default drivers, in order to get past the "TUFS" error message, I have to fully remove them or replace them, then I can boot without safemode (but still stuck at 1024X768).

Things I've tried:

---Graphics enabler yes / no

---NCPI=0x2000 / 0x3000 - This corrupts my Mountain Lion installation for some reason as soon as I try it. Its done it to me TWICE. No amount of safemode or bootflags gets me booted up again, it just freezes at different messages during the boot process right after where it initializes the ethernet driver. I can't even boot from my TonyMac installation USB boot drive and then choose my OSX partition. I even tried booting the installer and doing repair disk and repair permissions... nothing gets me back in after this! I can however boot into the Mountain Lion installer from the USB drive, and after a reinstallation, I can get booted up again.

---Replacing the new OSX nvidia drivers with mine modded drivers from 10.7.3 and even tried modded ones from 10.7.4. The driver seems to be getting loaded in the boot process no problem (I watch it closely in verbose mode), but I'm still stuck at 1024X768 when it boots. What the french toast?!

---PCIROOTUID=1 and 0 - This does nothing

---Injected EFI string for Graphics card in boot plist

Any suggestions would be appreciated! I love this board and want to be done with this issue already.
