Hoping for a real solution was a stupid thing to believe. I am throwing the mb in the drawer where it belongs. Going for the MSI AM1I.

Dear Szomoru,

Thanks for contacting ASRock.

For AM1B-ITX, it originally supports Microsoft® Windows® 10 64-bit / 8.1 32-bit / 8.1 64-bit / 8 32-bit / 8 64-bit / 7 32-bit / 7 64-bit / XP 32-bit / XP 64-bit.

Therefore, the AMD-Vi function is based on Windows OS.

We couldn't make sure if it can use in Linux OS.

we did the test in Windows 10 to create a virtual machine.

The virtual machine can work properly.

Please refer to the screen picture in attached file.

Thank you!

If they, CPU and MB, support virtualization in Windows then there is absolutely no reason they can't pass off to any other OS.

Hint: Good luck with that MSI Am1l

~~zmooky, what cpu is it you have?~~

Duh. MN. I see in the 1st post, Athlon 5350

My project was to build a small eco ( low power consumption ) pc with vm-s on it for different things like: small gaming windows vm, router, nas with plex media server and a web server

This was based on the fact that the devices can be virtualized in a passthrough way.

There is only one AM1 board with low power consumption that supports IOMMU but is from MSI - found it too late.

Does anybody want my AM1B-ITX mb ? :))

Without support for IOMMU by the CPU and/or chipset, there is nothing a mother board can do to bring it to the system.

If the CPU and/or chipset support IOMMU, then the board's UEFI/BIOS must be able to enable it, and then the board provide anything else IOMMU needs.

The AM1 Kabini SoC processors are specified to support IOMMUv1.

As wardog asked about, since the SVM option in enabled by default, which would enable IOMMU if it is supported by this board, if it doesn't seem to work, it must not be supported.

I must agree with WKjun, the single channel memory and low price of this board ($35 in the USA), most likely won't provide this feature. AMD systems that support IOMMU include 990FX chipset and FX processors.

I came across this link, which might help you enable it at the OS level:

"Memory and I/O virtualization is performed by the chipset."

"In addition to the CPU support, both motherboard chipset and system firmware (BIOS or UEFI) need to fully support the IOMMU I/O virtualization functionality in order for it to be actually usable."

https://en.wikipedia.org/wiki/X86_virtualization#I.2FO_MMU_virtualization_.28AMD-Vi_and_Intel_VT-d.29

Yes, there are several virtualization features and if there isn't an explicit IOMMU option, it is unusable I'm afraid.

As with most cheap(er) boards, it surely lacks even more BIOS/UEFI options like OC specific ones. Because it has just two memory slots and has its limitations CPU-(Core)-wise, virtualization is none of its strongpoints either.

But I wish you luck for a Beta BIOS that adds the IOMMU option for you!

I did not received yet and answer from asrock, but I found that it may be possible that the bios or mb is not officially supporting this. The virtualization option in the BIOS refers to AMD-V and not AMV-Vi as it is clearly state somewhere between the lines.

Next time I will read the manual before buying a mb :)

Without this the mb is useless to me.

None. Actually that was my error.

L prefix is for BETA BIOSes something here I deal with on a regular basis. I mistakenly entered L instead of P, which P stands for Production

I'm absolutely unsure if this has anything to do with your problem, but I remember having this special "IOMMU Mode" option "64MB" regarding Linux. Maybe you need this to be implemented:
