Re: [Xen-devel] IOMMU and AMD 890fx

[Sander Eikelenboom <linux@xxxxxxxxxxxxxx>]

Hello Jens,

Hi All,

With a bios flash, biostar does also seem to support the IOMMU.
So it seems all 890fx mobos have a (beta) bios available to support the IOMMU !

Reply from biostar tech support:

Yes, this motherboard supports IOMMU with 89FAD629.BST BIOS. Enable IOMMU
function via BIOS. I have to attached a picture for you reference. Also, the
IVRS table will auto create when enable IOMMU function via BIOS.

<< Enable IOMMU >>

=> Chipset / NorthBridge Configuration / IOMMU / Change from Disabled to
Enabled.

<< BIOS Download Link >>
