How to enable "hybrid cross fire" on mobo Asrock m3a785GMH/128m?

[asr]

Goal: To enable "ATI hybrid cross fire".
Mobo: Asrock M3A785GMH/128M
Graphic card: Sapphire HD4670 ultimate edition.
Bios setting: "surround view" has been enabled.
Asrock AMD VGA Driver v.8.631 has been installed. Link: ASRock > Products > Motherboard > M3A785GMH/128M > Download
No other graphic driver has been or is installed.
According to manual this is how it is done.
According to manual I must now open "ATI catalyst center".
Then click "view", and enable "cross fire".
When I open "ATI catalyst center" I cannot find "view" in the menu.
How do I enable "hybrid cross fire"?
Thanks.

Dear Asr,

ATI doesn't mention HD4670 VGA card can support Hybrid CrossFire function.
Please kindly refer to AMD official website for VGA card HD4670 specificaton.
AMD official website

ATI Radeon X2400PRO and HD3450 can support Hybrid CrossFire function with a compatible AMD 7-Series integrated chipset.
Please kindly refer to User Manual page 23 for Hybrid CrossFire support list.
User Manual

Please check this question with your dealer to make sure if HD4670 VGA card can support Hybrid CrossFire or not.
Thanks!

Best Wishes

Thank you for answering.

In the meantime I wrote Asrock.com directly.
Asrock.com gav me the same answer.

I can only say, the vendor informed me, that all cards from 2400 or higher (including 4670 cards) are
supporting the feature.
He was wrong.

But that's why I wrote the question because I couldn't make it run.
