maltba Posted August 6, 2012 Share Posted August 6, 2012 Hey Guys, need some help with my Mountain Lion Installation. I have a very smooth running 10.7.3 with GraphicsEnabler=Yes and a custom Personality for dual Monitor Support. System specs are: Rampage II Extreme Intel i7 920 Sapphire Radeon HD 4890 2GB Current Custom Kexts in 10.8 are: FakeSMC - some old version don't know if it ever got updated but it works fine in lion IONetworkingFamily\Yukon2.kext IOBlockStorage - some patched plist for proper detection of the ICH10R chipset My problem is that the GraphicsEnabler simply does not inject the card into 10.8. I am not able to get to the login screen with GraphicsEnabler=Yes. If i boot with GraphicsEnabler=No then OS X is loading some generic NV50HAL driver which only gives me 1440x900 Resolution w/o QE/CL. This behaviour is also different from Lion, where even when GraphicsEnabler=No the right driver is picked but because of the wrong standard personality the dual monitors aren't working. Does anybody else ran into that problem and might give me a hint what i'm doing wrong? If you need more information i will be happily answer your questions. thanks in advance maltba Link to comment https://www.insanelymac.com/forum/topic/281558-solvedgraphicsenabler-isnt-working-on-108-radeon-hd-4890/ Share on other sites More sharing options...
eep357 Posted August 6, 2012 Share Posted August 6, 2012 NV50HAL is a nVidia driver/kext, try deleting it and see what happens Link to comment https://www.insanelymac.com/forum/topic/281558-solvedgraphicsenabler-isnt-working-on-108-radeon-hd-4890/#findComment-1841666 Share on other sites More sharing options...
maltba Posted August 6, 2012 Author Share Posted August 6, 2012 i don't think that this would work. i've tried this before on lion because this kext was always loaded when i messed up my ati4800Controller.kext, while editing the personalities. when i've tried that on lion it crashed my hole system. maybe someone with a working 4890 on 10.8 could provide me his ATI4800Controller.kext and his ATIRadeonX2000.kext that would be awesome. thanks in advance.

maltba Posted August 7, 2012 Author Share Posted August 7, 2012 sorry my internet was messed up yesterday evening -.- i tried this though but it doesn't seem to work. Also it seems like i don't even get this ***DEVICE IN SLOT-1*** Message which i usually get on lion before the gui starts up. To me it really looks like chameleon isn't injecting the graphic card correctly. I will try to change the pcie port of the card now because i've changed the port recently to the 2nd one, because the first one had some strange problems. Furthermore i will try to set up vnc on mountain lion and try to vnc into it when its booted up fully with graphicsenabler=yes and post some ioreg stuff. Will report back soon.

maltba Posted August 7, 2012 Author Share Posted August 7, 2012 Ok guys i fixed it. Just forgot to update the Kernel Caches after I Installed the Kexts from fantomas. -.- Single Display is working now but no dual display but this is a problem with the Motmot Personality which i can fix myself. Many thanks for your help A Difference from 10.7 is although definitly that the 4890 isn't wokring anymore without the qe/ci patch. althought this isn't a problem if you know it^^ For everyone reading this thread: GraphicsEnabler=Yes fantomas 48xx qe/ci Enabler kexts !!use cvads kext utility to install the kexts!! and then everything will run smoothly. see you maltba Link to comment https://www.insanelymac.com/forum/topic/281558-solvedgraphicsenabler-isnt-working-on-108-radeon-hd-4890/#findComment-1842008 Share on other sites More sharing options...
