How to install NVidia 7600GT?

Eldarion · #1 01-28-2010, 10:19 PM

Hello Forum!

I just got Leo4allv4.1 working on my PC (specs see in signature) but have one question, i hope i get some help here in this Forum...

So, Sound & LAN ist working great, but i don't know how to install my Graphics Card (NVidia GeForce 7600GT 256MB PCIe) correctly.

At the Installation of OSX i didn't select any Driver for the Graphics Card, but i have now installed the NVKush Installer. After reboot there didn't change anything! So maybe there is a special way to "activate" the Driver?

Here's a screenshot of my Monitor Pane:

It would be a great help if someone could tell me what to do... i searched through half the internet the whole day and didn't found any solutions.

I have a similar graphics card and have had success with NVkush, NVinject and most recently with an EFI string in my com.apple.Boot.plist

I would first check to see if the file is in your /System/Library/Extensions folder. If so than lets try to correct permissions and remove the extensions cache. Open Terminal and type:

Code:

sudo su
cd /System/Library
chown -R root:wheel Extensions/
chmod -R 755 Extensions/
rm -Rf Extensions.mkext
touch Extensions

Reboot with -v -f

Sometimes these installers do not fully perform all the tasks for installing a kext. If the above does not fix the problem than you can try an EFI string. I used EFI Studio to generate mine. It also has a feature to place this information in the proper place in your com.apple.Boot.plist file. You will have to remove NVkush prior to using this. You can do so by following the commands below. Use google to search for EFI Studio.

Remove NVkush (The rm command is permanent so follow precisely)

Code:

sudo su
cd /System/Library
rm -Rf Extensions/NVkush.kext
rm -Rf Extensions.mkext

Since you are getting cozy with Terminal you may want to create a backup copy of your Extensions folder. This could prove very handy down the road.

Code:

mkdir /Backup
cp -R /System/Library/Extensions/ /Backup

Thanks for your detailed answer!

I have tried now following things:
1) Installed NVkush, corrected permissions and deleted cache files, reboot with -v -f --> no changes at all!

2) Deleted the NVkush.kext from the Extensions folder, copied the NVinject.0.2.0_dual_cards kext into my Extensions folder, corrected permissions and deleted cache files, reboot with -v -f --> again, no changes at all!

3) I deleted the NVinject.kext from my Extensions folder. Then I have loaded EFI Studio, and started it. I selected my Device (nVidia GeForce 7600 GT - 256 MB) and klicked on "Add Device" and on "write to com.apple.Boot.plist". Then I rebooted my system, and again, no changes at all - my Monitor Pane in the System Preferences always look the same, and the Resolution of both of my Monitors is still 1024x768.

Maybe i have done something wrong? Or is there another possibility to get my Graphics Card to work?

Thanks for help,
Eldarion

Edit: Here is the actual content of my boot.plist:

Are you saying that your com.apple.Boot.plist looks word for word like this?

Have you converted this EFI string from XML to hexidecimal form. Its usually included into your com.apple.Boot.plist like this under the device-properties key.

They key still being one fix at a time Injector kext OR EFI String not both at the same time.
