I've got the following answer from Biostar in respect to the Biostar TA890FXE main board. http://www.biostar.com.tw/app/en/mb/introduction.php?S_ID=482 <quote> The motherboard supports IOMMU, but the CPU you are installing also must support IOMMU. support@xxxxxxxxxxxxxxx 626-581-1055 menu select 2 </quote> I've just took the risk to order this mainboard as the main board is relatively cheap and I hope/presume the IOMMU will be supported eventually if it's not supported yet. I'll update you when I know the result. I understood IOMMU is not related to the CPU i.e. IOMMU should also be supported when the CPU on the main board is a AMD Phenom II X2 550 Black Edition?
