Asus P5Q, Mountain Lion wont boot, no panic.

Hello everybody


so here the Story of my install:

i had a running System with 10.7.4 on a Asus P5Q, with a E8400 and a Nvidia GT430.

i tried to install the GM Mountain Lion but had no Video. From a Source i needed to Patch the NVDAResman, NVDANV50Hal and NVDAGF100Hal.kext.

Since then i could start the setup of Mountain Lion.


after the installation was i started the System and got Panic from IOPCIFamily.kext.

So i started to search on some Forums. i stumbled upon a thread where a User (domino (from this board)) comfirmed a working Mountain Lion on a Asus P5Q.

i asked him that to give me his IOPCIFamily.kext and he provided this:




I only have the P5Q, NOT Pro. these are the kexts I use in S/L/E. I do not have any kexts in E/E. The colored are from the community. The non-colored is the original from ML. You should post a screen shot and maybe the community can help.




I installed all of these kexts and since then i had no IOPCIFamily panic anymore.

how i'm stuck at this attached Screen when i run OS X in verbose (normal run gets me the restart msg).


i also heard that the Geforce GTX550 Ti works OOB with Lion and i wanted to upgrade anyway so i bought that Card today and replaced the patched NVDAResman, NVDANV50Hal and NVDAGF100Hal.kexts with the ones from the BaseSystem.dmg


does anybody have a solution for this?

current System on Signature.

Thx for replying.


i checked my S/L/E and there is no fintek.kext FakeSMC Plugin.

so i'm kinda curious why fintek is showing me errors anyway..


also thx for providing the Link.

i just started the Thread just because i didnt knew any point of start or didnt knew any cause of the Problems.

okay the first one was a update from Lion to Mountain Lion.

now i made a fresh install on a fresh HDD.


i'm stuck at this screen on the updated Lion (picture 1)

and stuck at this screen on the fresh install on the new HDD (picture 2)+


boot options are GraphicsEnabler=Yes, npci=0x3000 and darkwake=0

also UseKernelCache is enabled.



i now did not use the provided fixes from the User on the Forums with the IOPCIFamily.kext etc.

i used now all default kext on the InstallESD. Now i get promtly that error (picture 3) on the fresh install hdd.

i also need to use "npci=0x3000" to boot up the installusb stick. after that all my HDD's are Orange in the Harddisk drive tool.

Hello everybody- after some research i guess its the Graphicscard again.

a 3GB Version of a GTX 550 seems not to work since OS X seems to not like more than 2 GB.

i will post my results with a other card maybe. thx for help anyway.
