I'm using a Z170 Extreme6+ with a Core i7-6700K. No OC other than XMP.

If I enable Advanced -> CPU Configuration -> Intel Virtualization Technology in the BIOS, VT-x comes up as "not supported" in Windows, however if I disable the same setting, it's reported as "supported but disabled". This happens on both P2.00 and P2.50.

I'm using HWiNFO64 and VirtualBox for testing. Is there something I'm missing? My goal is to have both VT-x and VT-d.
