After installing MultiBeast - go to System/Library/Extensions and delete NullCPUPowerManagement.kext and AppleIntelCPUPowerManagement.kext.
Then use KextBeast to install the downloaded AppleIntelCPUPowerManagement.kext from the post i left behind.
Restart and G2G...
how did you fix the network/internet problem I am stuck here myselfI haven't had the same luck. I have a Sabertooth Z77 and Radeon 6950. Removed the 6950 to install Mountain Lion and was successful, followed your method and I have a boot and working sound, but do not have full screen resolution (still booting through IVY Bridge integrated graphics) and have no working internet connection anymore. Don't know why I'm having different results. Any thoughts?
Update - Fixed the network problem. Only thing left is getting Mountain Lion to boot up through my Radeon 6950 without getting the white screen of death. No such luck so far. Is there a fix for this yet?
So if i got this right this is what my MultiBeast is supposed to look like (FYI I have a Gigabyte Radeon HD 6870)
1.)EasyBeast
2.)System Utilities
3.)Device Injector + AppleHDARollback + NonDSDT Enabler 892
4.)Trim Enabler
5.)ElliottForceLegacyRTC
6.)FakeSMC + FakeSMC Motherboard + AMD Radeon + HW
7.)NullCPU + USB 3.0
8.)10.7.4 Power Management
9.)hnak's Intel Ethernet
10.)Chimera
11.)iMac 12.1
Then after i come here and download Chimera 1.11 and install it. After this i'm a little confused.
