    ASUS claims VT-d is actually only VT-x on their board.. what can be done?

    dvorak2012

      I have been exchanging emails with Asus over the past few weeks, trying to get VT-d working in Xen on a P6T (X58) series board with an i7-920.

       

      Does Intel have any say in how their technology is implemented  by a company like ASUS (if it is not being implemented properly?)  because ASUS is showing no effort to fix this. There is supposedly a beta BIOS that has working VT-d, but it was never released to public (http://wiki.xensource.com/xenwiki/VTdHowTo).  The problem has been reported to Asus, for years now, that VT-d is not  working in Xen nor ESXi on this board, but they are leaving the VT-d  option in all BIOS updates and it still doesn't work when it is turned  on!

      Please help me out here, if it is at all possible. Also note that a VT-x setting in the BIOS is available, and is a separate option from the VT-d setting.

       

      Thanks.

       

      Here is a transcript of my communication with ASUS so far, with all sensitive information stripped:

      Hi Andrew,

       

      On P6T Deluxe V2:

       

      Page 3-28 of manual under section "3.5.2 Chipset" states Intel VT-d
      configuration 'Allows you to enable or disable the Intel Virtualization
      Technology for Directed I/O'

       

      This is the feature I would like to use, and it is included in the
      manual for this board and the option for the feature is present in the BIOS.

       

      Please review my request for a BIOS that implements the feature properly.

       

      Regards,

      Dear Valued Customer,

       

      Sorry for my delay.
      It is Vt-x.

       

      Best Regards,
