AMD Phenom II X4 model 920, uses .0875 to 1.425 Volts, (DC),

http://en.wikipedia.org/wiki/List_of_AMD_Phenom_microprocessors#.22Deneb.22_.28C2.2FC3.2C_45_nm.2C_Quad-core.29

That is the average voltage range for the AMD Phenom II X 4 processor.

Look back at the AMD Phenom chart again on Wikipedia, and look especially at the voltage range for the 900e to the 945.
Now look at the ECS CPU Support page again, and you'll see your motherboard supports Phenom II X4 processors from 900e to 945.

Since the 910e and the 925 are supported, I know the technology of the 920 is supported.
The Core architecture and nanometer technology it is based on, is supported.
No BIOS update may be needed.


Yes is the answer.

For additional questions please post in a Comment.

[NOTE*
That processor can use up to 125 watts of power. You need a decent Power Supply.
That processor also gets H-O-T!
Make sure it has a GOOD cooling system, and the computer case inside, and the Power Supply, inside, are kept clean ]

MAC OSX cannot be installed on a pc that uses a AMD Phenom processor and/or new ATI chipsets - the cracked version you try to use will work (badly - very unstable) only with older models of AMD Athlon and nVidia chipset. The BIOS settings have nothing to do with that.
Get a Linux like http://www.mandriva.com/en/downloads/one/ instead

I know that there are issues with OSX on AMD systems. Have you looked over at the OSx86 project page? I would start there if you have not.

If your systemwill start in "safe mode" you can try a a'system retstore" back to when it was working.
Let me know if this helps through "add a comment" at end of soloution.

try the delete key if that does not work try the f2 key

Press either delete or f2 during the boot up process to enter BIOS the scroll down to advanced bios features press enter change your first boot device to cd,press escape then press f10 to save to cmos to restart

do you have the setup cd that came with the board. the drivers probably need to be installed. if so run the disk and install the drivers and it will work.

Try clearing the cmos bios on the board there is a jumper on it

No need to reset your BIOS to enter BIOS editing mode.
You'll need a keyboard that plugs directly into the keyboard port, not a USB keyboard. The USB keyboard does not function until later in the boot process and therefore doesn't send the DEL keypress signals when needed at initial boot-up.
Using a direct-plug keyboard, keep tapping the DEL key while your computer is booting up and it should catch the keypress at the appropriate time and enter BIOS editing mode. This way you don't have to get a single keystroke timed precisely to open the BIOS editor. If the computer starts beeping at you, don't worry about that. It's just telling you that you've filled up the keyboard buffer with DEL keypresses which is the intent.
Hope this helps, and please rate my answer.

try go to BIOS..upon booting up your (turn ON the computer) immediately press "delete / F2" button then check the booting sequence. Make sure its not in default mode, try to rearrange the sequence by pressing "page up/ page down" button.Make your CD ROM as your first boot sequence next to hard drive..

Goodluck!!!!
