I just upgraded my S5520SC-based system with a 285 GTX to Mountain Lion. The installer worked fine, but when I reboot, no matter what I try I cannot get the video to work. GraphicsEnabler=Yes, PCIRootUID=0, EFI strings, nothing. Any tips or ideas out there? I looked at a bunch of threads, but nothing that helped.

[VirtualGuitarist]

Just a noob suggestion: have you tried PCIRootUID=1?

You could also try npci=0x3000 (with or without PCIRootUID=1), this is directly related to graphics and can help in certain cases.

Because this is the only way to boot ML on my config...

[justroach]

Yes and yes. . Thanks for the tip though.

[VirtualGuitarist]

Have you tried older versions of nvidia kexts? Or those directly from nvidia?

[justroach]

Yes, I installed the Cuda drivers that you linked to there. I tried installing the "Retail" driver as well, but that through an error saying that a driver was already installed. The card shows up in the System Profiler, but doesn't show any ports or displays...

[justroach]

I just tried a clean install instead of upgrading and ended up with the same result. If I boot from the USB drive and then select the drive I installed on graphics work fine, but if I boot directly to the drive that I just installed on I get nothing but a black screen.

[VirtualGuitarist]

So it's perhaps related to your version of Chameleon: the version installed to your USB drive is the version that works for you, so perhaps you should try to install different versions, just to see if one of them works better for you.

You could also try to see if there isn't in the /Extra folder of your USB drive a kext that's particularly useful for your mobo, and not present in the /Extra folder of your ML partition? By comparison you could know where the problem is...?

You could also try the app "MyHack", it's not magic but it can solves some problems...

I had exactly the same problem. The newer boot loaders are not injecting the properties of the GTX 285 correctly anymore. you need to inject via device-properties.

Anything that you can see I am missing as it still does not work?

[The-One*****]

Hi, I had the same problem, and I eventually tried using 'NVEnabler.kext' and it seemed to fix the problem. Hope this helps.

[justroach]

Can you point me to the version you used The-One*****? I tried that too, but all I got was a screen with distorted lines filling it.

For the heck of it I tried pulling out NVDANV50Hal.kext from /S/L/E/ and got video, but in a terrible resolution. My understanding is that the injection tools (device-properties, GraphicsEnabler, NVEnabler, etc.) all use the the driver from that kext and just allow the driver to see the PC versions of the cards. Is that correct? I'm going to try poking at the driver it looks like.

[justroach]

I tried swapping out NVDANV50Hal.kext with the version from NVIDIA's driver .pkg as well as from the installer USB thumb drive that the driver works perfectly on. Still no go. I can't see how the USB drive with the installer would work with the graphics card perfectly, but not the installed version. Any ideas as to what to look for for differences?

[TimeWalker75a]

You are missimg one importamt thing for this gen of cards ..
Change NVDA,GeForce to NVDA,Parent and it will boot with full acceleration etc..

[justroach]

Oh TimeWalker75a!!! So close! I have video now, but no QE/CI. Any ideas what I am missing?

[SiliconVoid]

Have you tried a clean install with just the last mod you did (via TimeWalker75a)?
The GTX285 was a gpu option in 2009/2010 Mac Pro (custom build) - it was supported by Mac OS (same as 8800GT).
I have used the same card in numerous test builds - never needed anything but PCIRootUID=0 to get to install screen, and GraphicsEnabler=Yes on a few occasions.

[justroach]

After some more digging it looks like EthernetBuiltIn and GraphicsEnabler are mutually exclusive. If I have EthernetBuiltIn set to yes GraphicsEnabler doesn't work. Anyone ideas what might be doing that?

[TimeWalker75a]

Bootloader probably has a hard time combining efi strings together.

[justroach]

Unacceptable!! I want a refund!

Looks like the best thing was to stick the Ethernet injection into DSDT. I tried to get my graphics card in there, but the best I could do was a resolution stuck at 2880x1800. GraphicsEnabler and the DSDT file looks to be my solution for now. THanks all for the help!
