Windows 7 Virtual XP mode

I am currently testing Windows 7 on a seperate drive and I want to install win7 Virtual XP Mode. Now i have checked my processor and it is capable of virtualisation technology but I can't find a setting on my AM2 motherboard BIOS which I thought would be capable as it's not to old. I have tried emailing abit but have got no response thus far. Anyone know of another way to tell if my motherboard supports this VT mode.
