Once you have recommanded to edit the boot.plist into iMac(11,1/12,1), now you using Mac Book Pro. Is that important to match the computer name/version for working the graphics card? Otherwise now can use any one - iMac or Mac Book Pro.
Waiting for your new updated guide & kexts.
Thanks Great Man !!!!!!
Basically you can use any smbios . Thing is : Ati 4670 mobility is in iMacs of late 2009, therefore a SMBIOS of iMac9,1 - 10,1 will auto-enable graphics-energy-saver settings. But I use MacBookPro5,1 because it works best with my Core2Duo speedstepping ( I don't use any longer nullcpu.kext ) - my MBP5,1 smbios will conflict with the Ati graphics-energysettings ( AppleGraphicsPowermanagement.kext ) , so I always edit this AGPM.kext in that way that I rename all instances of iMac10,1 to just MacBookPro5,1 ..
To make the Graphicscard "just work" and do so with QE/CI enabled the above details are not important. It is all about Powersaving/Eleminating the loud fan noise from the GPU..
Will this work for a normal Sapphire 4650 512mb? I am currently running iAtkos 184.108.40.206 and have installed various kexts (including ati4000).
Unfortuntely it crashes and shows a ("Turn off or restart" screen). I tried with GE=No and GE=Yes, as well as AtiConfig=Eulemer (gives a system error/halted). Unfortunately nothing works. Any suggestions?
It will work as long as your device id is 9480 and have a display that outputs via Laptop standard - LVDS ( not VGA, not DVI , not Displayport ) .
