Dell Precision M50 laptop NVidia Quadro4 GoGL driver C840 Inspiron 8200

I have a Dell Precision M50 laptop with an NVidia Quadro4 GOGL 64mb graphics card and I followed the instructions at http://www.thereformed.org/2007/05/01/howt...de-c840-part-4/ to get everything working. The Macvidia beta 2 driver did not work for me at first to change resolution. I got a black screen with different colored bands on the right hand side. Sometimes I would get a blank white screen. I finally booted off the install DVD and went to utilities and chose Startup. I chose to boot from the installed OSX on the hard drive at this point. My laptop rebooted normally and now gives me the option to change the resolution. It is working fine at 1600 x 1200. No CI or QE, but it works. Can anyone tell me why or if there is a better solution? This may help people who have a latitude c840 or an inspiron 8200, because I've read they all use the same motherboard.

Well, I've finally found a solution. If I use the MacVidia 1.0.81 files following the directions at part 5 of the C840 guide at the Reformed website. No QE or CI, but who cares? The confusion for me came from my Quadro4 500 GoGL 64MB card (NV17gl). It is very similar to the Geforce440 Go card (NV17), not the Quadro4 700 GoGL (NV28). That is why NvidiaEFI didn't work for me and MacVidia did. I'm now able to use any res I want including the native 1600x1200.
