Hello, thanks to some great tutorials and user tools, I've been able to install OSX Snow Leopard on my PC.

The only problem I am having, is that I cannot get the system to recognize my ATI HD 4650 (1GB) Graphics Card, or at least I can't get any better screen resolution than 1024x768

I've installed a "Kext" tool that allows me to drop kext files onto it and have them written to the system. I've done this with some supposed ATI Kext files, and in my System Preferences, it now show a "version" of my Graphics card, however not the exact same one.

None the less, the only "Display" resolution option I see in System Preferences is 1024x768 - and my card is capable of much higher resolution.

I was also able to edit my boot.plist to include a string showing 1600x1250, but I can still only get 1024x768.

Does anyone here have any suggestions on how I might be able to get this to work effectively?
I've read through many, many posts and threads on the internet about this issue and have tried almost everything that has been suggested elsewhere.

I am sorry if I left out any critical information, as I am a NOOB x 1,000,000.

It looks like whatever kexts/methods that was used are not working correctly.
You should undo them if it does not work.
It should recognize you native resolution without entry in boot.plist.

I'm not sure how to "undo" them. Can you tell me how please?

Thank you,

It depends on what You installed.
For video card, follow installation method one at a time. You need to delete the old kexts first before installing new ones and also rebuilding/clearing mkext/caches for it to be effective. Otherwise it would interfere and won't work.

How do I clear these things? When I installed kext, I just drap and dropped them on the Kext Utility. It installs them automatically. If you tell me where they are installed, I can delete everything.

Thank you for your help!

You only need to delete/move the kexts that you installed, not everything related in the system folder, as many of these cards need more than one set of kexts, along with correct install method to work properly.
The kexts should be in /S/L/E (/System/Library/Extensions) folder.

Here is a link for your ATI 4650 with installation instruction.

See if it works for you.

Okay, I did delete everything in the Extensions folder.

I will look at the beta booter, but I don't know what my devid is, and I don't know how to type the key or string in there. I am lost pretty much. I don't know anything about kext or strings or anything. I am sorry I am so stupid. I just need some help my friend.

I've got a similar problem with iPortable on Gateway M6827 laptop. The only resolution choice is 1024x768. It should run at 1280X800 with the GMA X3100. When I open EFIStudio no Intel cards are listed. I've not installed any kexts other than what came with iPortable. The add device Editor is gibberish to this newbie. I just got lucky with iPortable after trying many other tutorials. The screen resolution is bugging me to death and I want to fix it before making any other changes or additions. Thanks for any help forthcoming.
