adding VT-x feature in BIOS AWARD

Hi Everyone,

I have a Shutlle SB83G5 with a Pentium 4 and motherboard FB83V10. ( lga-775 )
Runs just fine.
I've changed the CPU with P4 662 which has EMT64 and VT-x features.

I can use the x64 ( installation of windows8-64 in a VMware machine, BUT i cannot use the VT-x feature because the AWARD BIOS is too old 20/7/2005....

can anyone help me ? how can I add the VT-x ON even hardcoded in the bios ?

many thanks
regards
Antoine
