Hi,
Do other chipsets than Q77 support VT-d I/O?
Officially, e.g. Z77 does not support VT-d I/O, see:
ARK | Intel® Z77 Express Chipset (Intel® BD82Z77 PCH)
However, I found this list of motherboards that support Intel VT with Directed I/O
Desktop Boards — Compatibility with Intel� Virtualization Technology (Intel� VT)
