This bios has a specific option for IOMMU. For intel chipsets, it
would be a seperate option called "Directed IO for VT", "VT-x", or
something mentioning VT. Not exactly sure what AMD calls it since I do
not have much AMD hardware. In my experience gigabyte's bios doesn't
typically have IOMMU options for either intel or amd.
