Pre-Installation:
Bios Settings:
*SpeedStep on (don't know if it works or not)
*Virtualization on
*Change drive option to legacy (if kept in normal, will get 'still waiting for root device' even with patched ioatafamily unless I ignore kernel cache)
Followed Unibeast install method:http://www.tonymacx86.com/61-unibeast-install-os-x-mountain-lion-any-supported-intel-based-pc.html
*Don't select legacy usb support
*Install patched ioatafamily kext into E/E of usb drive so installer can detect internal hard drive

*Removed ATI6000Controller.kext from S/L/E and backed it up elsewhere (because of Radeon HD 6670)
*Repair permissions of usb drive with kext wizard

Installation:
Followed unibeast install method but used boot flag GraphicsEnabler=no (6670 only)
Bios was reset so I had to fix that
Post Installation:
In multibeast, chose UserDSDT, VoodooHDA 10.8.4, EvOreboot, NullCPUPowerManagement

Installed BCM7522D (kext wizard) to S/L/E:
http://www.osx86.net/view/3074-bcm5722d.kext.html for network card
Installed patched IOATAFamily (kext wizard) to S/L/E to prevent 'still waiting for root device' error
Installed backed up ATI6000Controller back into S/L/E (6670 only)
Opened champlist:
http://tools.inmac.org
Added boot flag 'Force HPET' and smbios iMac 9,1
Create DSDT to finally solve 'Still waiting for root device error' (along with the patched ioatafamily.kext)
Download DSDT Editor:
http://www.insanelymac.com/forum/topic/223205-dsdt-editor-and-patcher/
In DSDT Editor:
File->Extract DSDT
Patch->Open (navigate to where dsdt editor is downloaded, open 'Patches' -> IoataFamily
Click 'Apply'
IASL->Compile->Fix Errors
IASL->Save AML as (save is as 'DSDT.aml' and save it to 'Extra' folder)
To Resolve App Store Error
Opened EFIStudio:
http://www.osx86.net/view/91-efi_studio.html
Ethernet->Add Device->Hex String to Clipboard
Pasted hex string into device properties via champlist
Went to System preferences->network and deleted anything there
Then went to Library/Preferences/SystemConfiguration and deleted NetworkInterfaces.plist
Repaired permissions and caches via kext wizard
Removed usb drive
Rebooted into new installation
Problems:
My 6670 appeared as 6xxx in system profiler but I still had full graphics accel and qe/ci so whatever (chameleon chose pithecia frame buffer on without the need of a boot flag)
*Edit: edited AGPM.kext for the 6670 so the 'unknown platform' error goes away. Still shows up as 6xxx but may have full graphics power management now.
Sleep
Putting the computer into sleep manually by hitting the power button works fine, but auto sleep is glitchy.
I had to open champlist and remove the darkwake=0 boot flag.
Then In System Preferences->Energy Saver, I had to uncheck 'Put hard disks to sleep when possible' and 'Wake for ethernet access'.
Finally, I had to set the sleep timing in Energy Saver so the display went to sleep before the computer.
Auto sleep works now, but only wakes up when I hit the power button (and it takes a while). If I hit the keyboard, it'll start to wake up but then go back to sleep again.
**Due to people acting like little girls and creating lots of forum drama, my guide on wiki.osx86project.org is slightly different from this one. They do the same thing, but this one is just easier and more practical**
*10/11/13: updated to 10.8.5 and supplemental update via manual download/install without issues
