根據 http://en.wikipedia.org/wiki/AMD_800_chipset_series

Full IOMMU functionality requires a BIOS with an ACPI IVRS table present. Currently only some 890FX motherboards provide an IVRS table[1]:

* ASRock 890FX Deluxe3
* ASUS Crosshair IV
* ASUS M4A89TD Pro
* ASUS M4A89TD Pro/USB3
* Biostar TA890FXE(latest BIOS required)
(當然啦，這個list未必跟得上腳步，僅做參考)
