Hi

anyone could help me with a GTX 460? after enabling graphics in boot.plist i only get a black screen. no errors...

Many thanks

Mike

 

I've been having the same issue with my GTX 460. So far, I've made no progress with any combination of 10.6.7, various versions of Chameleon, PCIRoot, and most recently, a custom DSDT. I have tried both the modified and direct from NVIDIA driver packages and neither makes much difference. I've also added my card's ID to the Info.plist to no avail. My guess is that the driver can't successfully select the right output on some versions of the GTX460 like the Zotac I have.

I've tha same zotac. Now if i set graphics yes in boot.plist it says no vram in profiler. if i don't set this it says 128mb vram. I've 1024MB with the GTX460, anyway i only want to test some 3D apps but they say that i don't have the minimal 16vram etc. Could it be that the opengl 1.6 frameworks is to old? i don't care about fps i only need to test. many thanks Michael

Use Chameleon 2.0 RC5

Run at least 10.6.5

Install the latest Quadro 4000 drivers from nvidia

Find out if you need PCIRoot=1 in your /Extra/com.apple.Boot.plist

 

If you've done all of that, it should work.

 

Unless there really is something different with the Zotac cards.

I try that again. As for the software i've that or even newer. It took long to get even that far. Before I had a black screen and lots of other weirdies.

Thanks

This doesn't change anything. withou nvinject i only get a low res. setting grahics to yes gives black screen, changing pci root doesn't change anything.

 

I had to twice move back the backup...is the hfs+ journaled that crappy? :D

using non journaled now...seems better. Also tried nvenabler but get kernel panic with that only. Any more suggestions?

Thanks

HI Toe Dirt

I've seen some tutorials but don't understand. Could you explain easily how to use my device ID as above. I want to try that as well. As other GTX460 are reported to work it must be some Zotac glitch. Some ideas on what else to try?

Thanks

All GTX 460 cards have the same device ID, 0x0e22.

 

There is nothing you can do with that device ID that will help, the Nvidia Quadro 4000 drivers already "understand" this device ID.

 

I maintain (unless Zotacs are somehow different from all other GTX 460 cards) that if all the conditions I listed above are met and the card isn't working, then there is something wrong with your injection method.

 

The only difference between the drivers posted on the tonymac website and those you can download from Nvidia is that the MacPro3,1, 4,1 and 5,1 model identifier installation checks have been removed. This you can easily do yourself by editing distribution.dist inside the installer package with a text editor.

 

Either way, whatever it turns out to be, the problem you and the other guy is having is definitely not with the Nvidia drivers themselves.

 

From a quick Google images search I can see that some Zotacs do seem to have non-standard outputs, it looks like dual HDMI and dual DVI? I guess it's possible that that could cause trouble with display detection.

You could try using NVENabler and experiment with injecting the 'display-config' property. Read the NVEnabler release thread over on the ProjectOSX forums for more information.

I have the same exact problem with my Zotac GTX 460 1GB. It worked fine ONE time, with full acceleration and identification. The only problem was it seemed to be limited to 1600x1200 (my monitor is an Apple Cinema Display 30", 2560x1600.) But on the next reboot, after installing some Realtek ethernet drivers, it stopped working.

Could one of you with a Zotac GTX 460 extract the BIOS from it, zip it and attach it here?

 

I will try to ask a favor from someone who knows more about this, maybe the ROM can be patched so that the card will work better with OS X.

 

You can use NVFlash (windows command line app) or GPU-Z to dump the ROM to a file.

Cool, thanks Krazubu!

 

Okay so let's see what we can do with this, I can think of two ways.

 

Method 1:

Set GraphicsEnabler=n in /Extra/com.apple.Boot.plist - use NVEnabler/NVEnabler64.kext and add the provided NVCAP and display-cfg strings to its info.plist. You have to make it load the modified ROM as well.

More info in the NVEnabler release thread over at the ProjectOSX forums:

http://www.projectos...p?showtopic=370

 

Method 2:

Install Chameleon 2.1

 

Name Krazubu's patched ROM 10de_0e22.rom and place it in /Extra

Edit your /Extra/org.chameleon.Boot.plist and add this:

 

GraphicsEnabler=yes

UseNvidiaROM=yes

VBIOS=yes

NVCAP=04000000000003000c0000000000000a00000000

display_0=03030100

display_1=FFFF0801

 

You can also make a plist with only the display-cfg values, use gfxutil to convert it to hex and then inject it via device-properties string in /Extra/com.apple.Boot.plist. This will work fine alongside GraphicsEnabler=y (I've done it myself).

 

It's also possible to inject just the display-cfg via gfx0 device in DSDT, this will work alongside GraphicsEnabler=y as well. I'll post example code later.

 

Method 3 (has a disadvantage if you're running Snow Leopard):

http://www.insanelym...dpost&p=1696332

 

Now get cracking!

So I tried route 2 with my card. I added everything you suggested and tried injecting display-cfg properties because I use AnVAL for Sandy Bridge support and noticed Valv had implemented jingu's patch a long time ago. However, I didn't get any change. Unless I didn't use the right key for display-cfg? The proper syntax seemed kind of hazy for Chameleon.

You'd have to ask Valv how he implemented it, or maybe you can find out yourself by looking at the source code of his branch over here:

http://forge.voodooprojects.org/p/chameleo...D/branches/valv

In Jingu's code example he hardcoded the display-cfg values that worked for him.

I already posted how to do that on the previous page!

If you're having problems following a specific part of my instructions, let me know.

 

It's probably easier if you just use NVEnabler.kext, it can load the patched ROM and lets you set the NVCAP and display-cfg overrides as well.

 

See the NVEnabler release thread over on the ProjectOSX forums for usage instructions.

How to load an alternate VGA BIOS :

Open NVE plist with a plist editor. Add a child inside the section "addProperties". Set its name to "vbios" (has to be in lower case), its type to data, and past the BIOS in hex in the value field.

Also remove the entry "skipvbios_disabled".

 

Don't understand that. Could someone paste a correct file for me to try? Many thanks.

Don't understand that.

 

That's because you aren't following it to the letter. Like it says, use plist editor that comes with Apple xcode to edit the plist.

Once you're looking at the plist in that editor the instructions will be easier to understand.

Adding "a child", "set its type to data" and "value field" are all terminology from that editor.

 

Open the BIOS in a hex editor (google 0xED, it's free) and copy/paste from there.
