What desktop boards support VT-D or IOMMU? [closed]

Look at http://wiki.xensource.com/xenwiki/VTdHowTo , consumer boards are hit and miss but server boards are always work. I would use the parts recommended here napp-it.org/napp-it/all-in-one/index_en.html. The Supermicro X8SIL-F is a good choice.

There are currently 6 desktop boards that support VT-d listed by Intel:

Support of the board is not fully accurate information, VT-d is about CPU (beware of stepping C1), chipset (as Michal linked), BIOS (many times it depends on CMOS Setup choice), OS (in case of linux you should have proper kernel modules) and VM solution.
