F2A85X-D3H not able makeing 6670 to hybrid crossfire with A10 apu.

[Suntoucher]

Hello, hope someone can help me out.

MB: F2A85X-D3H
APU: A10 5800k
GPU: Sapphire 6670 1GB DDR 5
RAM: 2x4 GB DDR 3 Kingston HyperX Performance 2400

Connected monitor to GPU via VGA cable.

In bios I do not see option to enable dual graphics, all I get to is this
-Primary video device = NB
-Integrated graphics = force
-Uma Frame buffer size = 2 Gb

Where do I enable dual graphics?
I did some reading on web and all around web they say you just plug your supported GPU and install new drivers from AMD, and AMD VISION Engine control center should offer you that option. Unfortunately this is not the case, I even re-installed system, but still not able to make it work.
Tried various combinations of selecting main graphics output on  APU, setting Integrated graphics on auto... Nothing yet worked for me

Anyone got knowledge to help?

I have run dual displays on nvidia and ati boards.  In both cases the second monitor/display had to be attached before the graphics sw would permit any sort of setup or manipulation of multiple displays.  I don't remember that bios had anything to do with this.

Install the latest driver for the Desktop Graphics/Accelerated Processors (APU).
Install the HD 6670 and connect the Monitor to it.
Start the PC and enter the BIOS.
Set Integrated Graphics to Force.
Set UMA Frame Buffer Size to 512M or above.
Save and Exit BIOS.
Install the latest driver for the Desktop Graphics/Radeon HD Series
Restart, go to the AMD VISION Engine Control Center.
Browse to Performance\AMD Radeon Dual Graphics and ensure the Enable AMD Radeon Dual Graphics check box is selected.

There is a icon for the AMD VISION Engine Control Center in the tray that you can right click on to see the program.
