Enable Hardware Virtualization on Latitude D820

I had a little trouble getting hardware virtualization enabled on my Dell Latitude D820. I think the first time I looked at the system settings (f2 when computer is starting up) the setting to enable virtualization was not present as my bios was not the latest version. (I upgraded to version A07. version with computer shipment was A04). After I upgraded I was able to turn this virtualization on by going into system settings (f2 when computer booting up) | POST Behavior | Virtualization. From here I could enable it.

Are you wondering how you can tell if hardware virtualization is turned on or possible to use on your computer. Try out this tool at grc.com
