I actually found it by just looking around in the bios. I have a quad that runs 32bit vista and I was wanting to upgrade to a 64bit windows 7. It (virtualization) was turned off by default. In checking for compatibility for windows 7 64bit, this was the only issue I found. http://www.grc.com/securable.htm
SecurAble by Gibson Research Corp. looks to see if your pc is 64bit capable and if not, what three things would make it possible. virtualization was one of the three. Now after turning on the virtualization, I reran the windows 7 advisor. I can now upgrade to windows 7 64bit using a custom install. Thanks for the reply.
