How to replace Video Card?

[remotestation]

I had a Nvidia (die) and have a spare Video Card...Nvidia 6800 PCIe or Quadro NVS 295 I would like to use...

 

But I get a Kernel Panic now and have to reboot...

 

How do I clear cache? or boot in safe mode to make changes to the KEXT ???

 

-x causes KP

-s brings me to a prompt...then what?

 

Or can I boot DVD then goto Terminal to FIX??

 

reset so I can boot into OSX and the use NVdarwin? inject??

 

or is there something better at this moment?

 

Thanks

 

*** Update *** found this?

 

Boot and get the boot prompt with the F8 key, type -s and enter.

This will get you to the single user mode.

 

Type the following :

mount -uw /

rm -R /System/Library/Extensions/NV*.kext

reboot

 

This got me back into OSX...now just have to figure out how to get my Resolution up to 1920 X 1200...
