Virtualization Locked Off

Bonjour,
je vient de testé mon ordinateur pour vérifier si je pouvais utilisé l'hardware virtualization
(j'en et besoin pour emulé mac os x via vmware)
avec le programme de Gibson: SecurAble
le programme me dit que c'est "Locked Off"

Virtualization Locked Off

This processor's advanced hardware support for virtualization has been disabled and "locked off" by some external influence - most likely by this system's BIOS as the system was booting. Since enabling hardware virtualization will allow faster and more secure virtual machines and their hosting operating systems to run at 100% full speed, you may wish to poke around in your system's BIOS to see whether you're able to find any references to "hardware virtualization" or "VMX", etc.

En cherchant dans le BIOS j'ai rien vue pour déverrouillé la virtualisation hardware
comment et ce que je peut l'activé ?
