OS X 10.5.5 and newer releases doesn't support nVidia GeForce FX 5200 because of enablers incompatibility and changes in CoreGraphics framework.

But with some amount of work it is possible to use this card with Leopard :)


RAN SUCCESFULLY WITH:
- 10.5.5
- 10.5.6
- 10.5.7
- 10.5.8

Step 1:


1.) Install OSx86 with no video drivers, injectors (NVkush, NVinject, etc.), nor AGPGart.

2.) Right after installation, boot with parameters -s -v.

3.) Remove all references to Geforce drivers:
CODE
/sbin/fsck -fy
/sbin/mount -uw /
rm -R /System/Library/Extensions/Ge*
rm -R /System/Library/Extensions/NVD*
rm -R /System/Library/Extensions.mkext
exit

Now your system shouldn't hang anymore, and you'll be able to create an account and login.

4.) Open OSX86Tools and click on Add EFI Strings/Boot Flag button.

5.) Click on GFX Strings icon, and choose Custom GeForce... from the Graphics Card

drop-down.

6.) Choose VRAM size (card's memory) and NVCAP (VGA/DVI-I if VGA is on the side of the

motherboard) and click on
Import String to Boot Editor icon.

7.) On the Boot Editor window, click on Apply changes to com.apple.Boot.plist and restart

your system.

You should now see in System Analyzer that your card is recognized, but no QE/CI.

Step 2:



1.) Install NVidia Universal Installer (Thank you MacNutty).
You will be logged-out and logged back in automatically.

2.) Open OSX86Tools , check Repair Permissions, Clear Extensions Cache and Touch Extensions

Folder, and click the Run Selected Tasks button. When finished, restart your system.

You should now see in System Analyzer that QE/CI is enabled, but with scrambled graphics.

Step 3:


To fix the graphics issue use Sanya method:

If you have a 10.5.5 dvd (i use IAKTOS 5i):


1.) Insert 10.5.5 dvd and open Pacifist.

2.) Click on Open Apple Install Discs, and choose your dvd.

3). When finished, use the search box to locate CoreGraphics.framework.

4.) Right click on it, and choose Install to Default Location.
Replace files if prompt.

5.) Restart your system.

If you don't have a 10.5.5 dvd (Thank you JESS Fortress):


1.) Download and install 10.5.5 CoreGraphics.

2.) Restart your system.

You should now have QE/CI enabled and working well.
