HURRAY..... F#CK YEAH
I have the graphics card installed..... finally after so many hit and trial methods. I am writing down the procedure that worked for me:
TRIED Baraka's Method (METHOD 3) but with minor modifications
1. Opened the EVOenabler and ATY_init folder, Open Applications folder in a seperate window. SELECTED ONLY 'ATY_init.kext' folder Instead of both 'ATY_Init.kext' and 'EVOenabler.kext' and dragged it over to 'Kext Utility' found in the Applications folder in order to install it automatically with permissions also being repaired automatically.
NOTE: I was getting a BLANK GREY SCREEN if I installed both the kexts (ATY_Init and EVOenabler) hence, only installed ATY_Init.
2. Opened ATI4350 folder and copy pasted 'ATI4350.Fix.v2.kext' file to Extra/Extensions folder.
3. Opened Controllers folder and selected all the files from Controllers foler and dragged them over to 'Kext Utility' in order to install them automatically with permissions also being repaired automatically.
4. Opened 'Kext utility' again by double clicking it, typed password and let it repair the permissions automatically AGAIN to be safe.
Restarted in verbose mode and VIOLA the Card was recognized and fully working with Quartz support. YES YES YES..... F#CK YEAH
