Does the "Intel Virtualization Technology" have a own ORom to mod a bios or is this a enable function for the CPU only?
My "Intel Virtualization Technology" is unstable on high grafic games. So I need to disable this function. The Problme is, that I need 64Bit GuestOS in VMWare. So I need to restart always when I need.

Can I mod this self with the newest ORom in Bios?

I have a GA-Z77-D3H (rev 1.0), Zotac GF560 Ti, i7-3770S Cpu, Win8.1 64Bit.
