Do you read my post?
http://forum.giga-byte.co.uk/index.php?topic=2844.0Your motherborad G31 chipset - doesn't support VT-d.
chipsets which support VT-d are:
Q35 / Q45 / X58 / 3450 / Q57
but I only know that INTEL's motherboards 100% support that, GIGABYTES - not testing, and I don't have money that buy and sold motherboard which don't pass test. I want to buy GA-Q57M-S2H (supprot IDE, HDMI, more cheaper PCI than PCIe, more SATA, optical interface and HD audio on back panel) - greate motherboard but this is too much risk for me
because GA-Q57M-S2H only have in bios VIRTUALIZATION TECHNOLOGY -> what does it mean? VTd/VTx/VTc? May be All, may be only VTx as that in greate motherboard with support USB 3 -> GA-H57M-USB3
thats why I bought Intel DQ57TM (don't have HDMI - have only DisplayPort and DVI - optional adapter cables cost ..., only have 1xPCI and 2x PCIe, only 5x SATA, have only on motherboard pins option S/PDIF, HD audio - in Gigabyte all this funcion you have in standard)
