BIOS Installation:

OS X Mountain Lion Installation:

1) Create a Bootable USB Stick with UniBeast
1.1) If you have got the same Graphics Card like me you must remove the "ATI6000Controller.kext" from the installation Stick (but save it to another USB Stick, USB Drive or whatever, you need it later) you can find it in S/L/E you must use the ShowAllFiles-APP from the Download section
2) Start installation from USB Drive press "F12" on the POST screen and select your USB Drive
2.1) If you have removed the Kext as in step 1.1) you have to enter "GraphicsEnabler=No"
3) Install Mountain Lion
4) Relax during installation
5) After installation reboot you computer aigain from the USB drive with "F12" and take the Partition where you install your Mountain Lion
5.1) If you have removed the Kext as in step 1.1) you have to enter "GraphicsEnabler=No" again
6) Now we are are on the fresh installed Desktop of Mountain Lion Start Multibest 5.0.2 and check the following boxes (don´t forget to put the DSDT, you get it in the DSDT Database):

6.1) If you have removed the Kext as in step 1.1) now you have to reinstall the Kext, put the saved Kext from 1.1) on your desktop and run KextBeast or install it with KextWizart and fix permissions and rebuild cache
7) Restart

I noticed that the boot from my SSD take longer as on SL or Lion and my DVD Drive is not shown as internal. I found a Thread that would solve my Problem (3rd Post on Page 3):
http://www.tonymacx86.com/mountain-...tain-lion-slow-boot-up-time-3.html#post419948

8) Downloaded the 3 Kexts from the post or the file that i Attached (i deleted the Kexts in S/L/E before i install it) and install it again with KextBeast (put it on your Desktop) or with KextWizard and fix permissions and rebuild cache additional you must run in Terminal (or it would not work):
sudo kextcache -v 1 -a i386 -a x86_64 -m /System/Library/Caches/com.apple.kext.caches/Startup/Extensions.mkext /System/Library/Extensions
9) Reboot
10) Enjoy your Mountain Lion on your GA-H67A-USB3-B

Everything works and tested!

What does not work?

Mountain Lion installation or the complete system?

The only thing what does not work is the HDMI Port, i had to use a Display Port to HDMI Adapter http://www.newegg.com/Product/Product.aspx?Item=N82E16814999034

and the DVI to HDMI Adapter
http://www.newegg.com/Product/Product.aspx?Item=N82E16812105832

In my Configuration the standard DVI ports and the Display Port work.

No Change in Chimera or any other kind, Card works OOB! (only the ML not)
