I did manage to get my computer to show my Video RAM as 512 which is great thing, but the resolution still at 1024 x 768 and can not change it.

I tried using EFStudio to generate the code and then add it to the com.apple.boot.plist with Graphics properties and resolution 1920 x 1200 (which my screen support) but after reboot nothing changed.

am doing something wrong or is there any other way to fix this.?

Thanks

I could be wrong about this but as its a laptop wouldn't that be 8600M GT not 8600GT?

Yep you are correct, But some pages just list it as 8600 GT

but from what I can tell the strings are very generic, and OS X does have
the drivers, its just not using them or not using them correctly


I just went over to the iPC OSx86 page, seams that the installer lists
Nvinject for various Video Ram sizes

You could try one of them, also the NvinjectGo was made for laptops

I'm not sure whether you have tried it already, however I recommend you do a clean install with NVkush, NVinject selected, do not install any other efi strings or enablers other than the two mentioned, just NVinject may help get maximum supported resolution but might not support "quartz extreme" and "core image" which is essential for Apple Front row and many other graphically accelerated apps like the album art browser feature in Itunes and NVkush does the trick, specially for Nvidia 8 series.

Thanks i ll try that but can you tell me which NVinject to use, i tried NVinjectGo 0.2.0 512MB VRAM and NVinject 0.2.1 512MB VRAM
as mine is 512 ram and what i got is a black screen?
or do i have to try all of them (they are a lot)

Thanks

You could always try NVdarwin 512MB, there also seams to be a
"Laptop Display "checkbox in the picture on IPC's web page, that
may help also

Try the ones listed for 512MB, and the the Defaults, only one at
a time

NVinjectGo 0.2.0 512MB VRAM - Already tried
NVinjectGo 0.2.0 Default
NVinject 0.2.1 512MB VRAM - Already tried
NVinject 0.2.1 Default
NVdarwin 512MB

I would go with johnnyboys recommendation people seem to have a lot of probs with 8600m main one being no QE/CI, seems that NVKush should do the job though
