Hello

 

I have an ATI 4850 and these obviously arnt supported. My board has two pci-e slots and I have a nvidia 9400 which im going to put in the second slot. My question is it possible to completly disable the ati card so osx doesnt output through it ?

 

Ie in windows ill disable the nvidia card in device manager.

 

 

last time I tried I couldnt figure out how to disable the ati card, I could output on the nvidia however I wasnt able to turn off the ati and only use the 9400

 

any ideas?

Sorry about my English.

Try:

Option A: swap 2 card, ATI card to slot 2, NVIDIA to slot 1

Option B : BIOS setup can select slot for VGA Master.
