Gigabyte GA-945P-S3 (Rev. 1.0) + CPU = where my vt-x ?

[mycop]

MB GA-945P-S3 (Rev. 1.0)
Processor Dual Core E5700
BIOS f7c: http://yadi.sk/d/P-GIsQVUPGZCi
Needed virtualization. The site stated that Intel percent vt-x support. http://ark.intel.com/ru/products/42801
Rejoiced too soon. Function is disabled in bios.
Include manufacturer it does not give the grounds that the processor is not supported. (List of supported just percents):

Communicated with gigabyte support. same answer. supposedly board does not support processor .
Decided to include this item in the BIOS enable
opened through the bios MODBIN6_20401 found in paragraph Virtualization but it turned out that he was there by default within the meaning of Enable
Menu item bios I certainly did not appear. (Here you can view the PDF as a menu http://yadi.sk/d/j-evE7s-PGaQj
It has been suggested that the need to update the CPU microcode, however processor with motherboard and work fine in the same BIOS perfectly defined. I think that is not the case.
I conclude that the manufacturer is limited to specific CPU

Is there a way to decouple processor affinity (or just cheat MB)?
Just include virtualization otherwise. (Preferably in the BIOS of course)?
Which way is best to start "digging"?

also second (not important) question. AHCI in this biose can be enabled?
