Hi terrorgen


I have a Point of View, Nvidia GT220 2048 Mb working 100% in ML DP4.


Method as follow;

Extract the Video Card's rom in Windows.

(There's a few methods that can be used to achieve this. I can not remember what I used unfortunately. You will have to Google)


Rename the file with the .rom extension as follow;

Details for my card is as follow;

Vendor ID = 10de

Device ID = 0a20

so that the file looks as follow;



You will have to get your cards Vendor and Device ID's and implement them as I did above.


Place this file in /Extra in ML DP4.

Install Enoch's Chameleon Bootloader r1999. (Works good for me)

Ensure that you use the following boot flags: GrahicsEnabler=Yes, UseNvidiaROM=Yes and VBIOS=Yes


Dual Monitor, Mirror displays, Resolution and QE/CI all working.


Attached is some screen shots.


Realy hope this helps you.


NOTE: This method has been working ever-since Snow Leopard.


Good luck



If I am transgressing any rules in posting the above, humble apologies in advance.

Here is an easier method;

Just found and tested this a few minutes ago;


Install attached kext in /Extra/Extensions.

Repair permissions and reboot.

It unfortunately states Unknown Nvidia Card else all is working 100%.

Playing Call of Duty 5 flawlessly.


Keep Chameleon settings as in above post.


That's it!
