I checked it with that tool, and it replied that it does support virtualization, which wasn't a surprise because the CPU is an A12 and so rather new. If there is anything that doesn't support virtualization, I think it would have to be the motherboard, but it seems weird that a 1 year old machine wouldn't support that. Am I doing it right? Is it just changing the one byte on line 000000E0 from 00 to 01? Doing that DOES make windows report virtualization on instead of off, but VirtualBox still says it is off and chokes.
