    s3420GPV virtualization technology for Directed I/O is greyed out in BIOS


      Can anynoe tell me why this feature;


      "VT for directed I/O"


      is greyed out in the bios?


      I can enable the "Intel Virtualization Technology" feature that is listed just above the greyed out feature and I have done a power cycle as described here:




      in section 3.10 it states that the 3420 chipset provides hardware support for intel VT-d, but still it is greyed out.


      The bios is version s3420gp.86B.01.00.004
