Nvidia 9800 GTSm 1GB - No Quartz Extreme

[methvenc]

I have been tinkering around trying to get my gfx card working with my Snow Leopard install. I am using a retail copy of Snow Leopard along with MultiBeast/iBoot (newest versions). Everything had been working fine for a while but seemed to stop being stable after 10.6.6. I have tried Nvenabler and using the 'GraphicsEnabler=Yes' on boot up but i get the same behavior which is a flickering screen and freezing.

Finally I came across aquamac's thread involving gfx strings. I removed nvenabler and followed the guide for single nvidia cards using the template provided. This resolved the flickering and freezing and my card (as far as I know) shows correctly in system profiler, problem now is no QE. I followed the guide using 10.6.6 and also tried using a Kalyway 10.5.2 install (the guide mentions there were issues enabling QE when outputting the hex in SL.) Unfortunately I get same results. Any help or advice would be appreciated, I will include my plist and template used below, as well as what system profiler shows.

Error:
Quartz Extreme required.
iMovie requires a graphics card that is compatible with Quartz Extreme. One or more of your graphics cards does not support Quartz Extreme.

I have removed nVenabler from Extra folder but I do not know if there is an extension in /S/L/Extensions that is conflicting. I have not removed any files from that folder, so whatever kexts are there in a vanilla SL 10.6.6 install should be there. Here are a few which I have noticed that perhaps are causing issues.

AppleGraphics control
AppleHDA
AppleGraphicsPowerManagement
AppleintelHDGraphics (several)
GeForce
geforce7xxxgldriver
geforcega.plugin
geforcegldriver.bundle
geforcevadriver.bundle
nvdanv40hal.kext
nvdanv50hal.kext
nvdaresman
nvsmu

Any help would be much appreciated to help isolate where the issue could be, any information I can provide I will, thanks in advance.

Issue resolved.

Issue was due to an update I did to the bios. Did not think about this during all the troubleshooting I did. I reflashed the bios to 9C.23 and reinstalled Mac OS X, everything is working fine using graphicsenabler=yes method.
