I had great success getting my 8600 GT 512mb to have Quark Extreme, etc. with iDeneb 10.5.5--




Used efiStudio. Had tried nvinstaller .52, and it showed the correct device ID, etc. but no Quark Extreme. Previously had it under 10.5.3, but with 10.5.5, it was gone. Thanks to efiStudio, it's back, baby!

My QE on GeForce 6800GS (0x00c010de) was working fine in 10.5.3. Installed 10.5.5 ATiKOS v5i with NVinject 0.2.1 - 512mb. Mod'd PCIDevice entries in GeForce.kext, my card specific NVDANV and the NVDAResman files. Mod'd NVinject as per guide on their forums ie ProbeScore to 0 and added DeviceID without mask (I already had it with the 0x0000ffff mask, left it there too) but still no QE support.


Discovered that the key to the solution if you want to use NV-type injector, was to remove all Ge* and NV* files from base install and boot using standard apple drivers, then most IMPORTANTLY install the Leo 10.5.5 9f23 graphics update. Remodd'd all necessary kext mentioned above with my PCIdevice ID for card with mask.., also decided to use NVdarwin injector as per the instructions NVinject forum guide re ProbeScore and NVCAP values. Had to use Plist Edit Pro to mod RAM value for 512MB and add my specific NVCAP for for card (see NVinject forums and site for details on how to do that, basically I created a DOS boot fashdrive and ran the NVflash util to save ROM, then used NVCAP maker to query NVCAP from ROM.)


Rm Extensions.mkext then reboot -f -v and presto. Nvidia injector worked and QE back on my 6800GS 512MB on 10.5.5.


Key was to remove the existing 10.5.5 kexts and apply the 9f23 graphics update. Presumably the NVinject 0.2.x should work too just found the NVdarwin to be better myself ie displayed Card Model automagically.


Hope this might help those that want a non-EFI Studio solution to the QE not supported on 10.5.5. Presume it'll be the same with iDeneb 10.5.5 or similar install too.

Okey so i installed 10.5.7 iAKTOS and everything is fine i enabled my video card (8600GT 256MB) via EFI Enabler in OSX86Tools but when i change my reslution i get a plain blue screen so i rebooted and i had max resolution... but when i play games in full screen mode fior example Halo, SIMS 3 i just get a black screen... but if i play halo in a window it plays perfect... and also when i minimize a quicktime movie i dont get a preview in the dock... but i have a transparent menubar and Quartz Extreme and GL enabled... any help guys ???? thanx in advance ;P
