Bios Mods -The Best BIOS Update and Modification Source

Hello guy,

I have any troubles for unlock in my Insyde Bios, the virtualization features (EPT, VMx, XD).
I try to enable Hyper-V for install in Visual Studio 2013, the Windows Phone Emulator, like it's write in this doc -->MSDN Link

I have an Insyde Bios :
- Insyde H20
-F.64 (Rev. a) --> HP Link

Thanks a lot for your help.

P.S : I take a screen who prove that my computer is a "SLAT capable machine"
