Gringo Vermelho Posted April 7, 2014 Share Posted April 7, 2014 If you want to use Device Properties Strings, you must generate them with gfxutil. Usage information available in the gfxutil topic in Netkas' forum. Link to comment Share on other sites More sharing options...

(8800GT generic string don't seem to work) no you don't need EFIString, GraphicsEnabler does the same work just install the kexts from iFIRE's post, use kext wizard for this and repair permissions et rebuild kernel cache boot with GraphicsEnabler=Yes flag or ... GraphicsEnabler Yes ... in your org.chamelon.Boot.plist Link to comment Share on other sites More sharing options...
iLeopard_PC Posted April 7, 2014 Author Share Posted April 7, 2014 I have installed all the kexts from iFIRE's post with kext wizard. After that i have rapaired permissions and rebuilded kernel cache... but nothing has changed If I boot with -v -f i can see a kernel panic My org.chameleon.Boot.plist: <key>GenerateCStates</key> <string>Yes</string> <key>GeneratePStates</key> <string>Yes</string> <key>EthernetBuiltIn</key> <string>Yes</string> <key>Graphics Mode</key> <string>1280x1024x32</string> <key>GraphicsEnabler</key> <string>Yes</string> <key>PciRoot</key> <string>1</string> <key>Kernel</key> <string>mach_kernel</string> <key>Kernel Flags</key> <string>-v</string> <key>Timeout</key> <string>3</string> Link to comment Share on other sites More sharing options...

iFIRE Posted April 7, 2014 Share Posted April 7, 2014 boot with -f -x -v npci=0x2000 and check if you have deleted the kext, repairPermissions with kext wizard app/reboot Link to comment Share on other sites More sharing options...
Rampage Dev Posted April 7, 2014 Share Posted April 7, 2014 I myself have had issues since ML with the 8800 GTS is a Core 2 Duo system. The only way to get it to boot in ML or Mav has been SSDT injection and the SSDT placed in the Extra folder of the installer... Link to comment Share on other sites More sharing options...
Gringo Vermelho Posted April 7, 2014 Share Posted April 7, 2014 Are you absolutely sure of this: My org.chameleon.Boot.plist: <key>PciRoot</key> <string>1</string> Injecting the wrong PCI Root value will prevent EthernetBuiltIn and GraphicsEnabler from working. (But yes 1 is traditionally used on Gigabyte boards) Link to comment Share on other sites More sharing options...

I guess I'll have to reinstall Mavericks... Are you absolutely sure of this: Injecting the wrong PCI Root value will prevent EthernetBuiltIn and GraphicsEnabler from working.

Gringo Vermelho Posted April 20, 2014 Share Posted April 20, 2014 That's news to me, I thought it could only be 1 or 0. Thanks for sharing. Link to comment Share on other sites More sharing options...
iLeopard_PC Posted April 25, 2014 Author Share Posted April 25, 2014 I have upgraded my graphic card from 8800GT to Palit GTX 560 1GB (no ti) and now Mavericks is working but i need some patch to DSDT because i have some freeze and low framerate in 3d game You should check the correct value of your PCI root by extracting the original BIOS DSDT table. On some computers, it is neither 0 nor 1 but a higher value like 4. Alternatively, use the following Terminal command: ioreg -l | grep -15 "AppleACPIPCI\ " | grep UID This is typically what I encountered on my Dell workstation and I could not get my nVidia 9800GT (which is just a revised/renamed 8800GT) to initialise properly until I set PCI root to 4 at bootloader level. I subsequently patched the DSDT to set PCI root to 0. Another solution is to use NVEnabler64 enabler kext. How can i patch my DSDT with PCIRootUID=1 (i have checked it with terminal and it says 1) That's news to me, I thought it could only be 1 or 0. Thanks for sharing. For me too Link to comment Share on other sites More sharing options...
Gringo Vermelho Posted April 25, 2014 Share Posted April 25, 2014 Go find the pinned topic "Tequila Fix" in the DSDT subforum. It should not be a problem that your PCIRoot is 1, you don't have to do anything. Link to comment Share on other sites More sharing options...
