Dear bios-modders,
I am searching for help and/or hints to get IOMMU working on this thin client ( Fujitsu Futro S920 - D3312-A13 3).
The goal is be able to passtrough PCIe ressources and use this little machine as lowpower virtualisation host with proxmox.
The SOC on this motherboard is a AMD GX-415GA which should be able to handle IOMMU for my understanding.
What I have done so far:
- update the board with the latest official bios version ( D3313-A1.rom)
- modifying the sections I found relating to virtualization with AMIBCPv4.55 ( I think mostly SVM mode was realvant here)
- update the board with AFUDOS and check results
- unfortuantely there is still no option to enabel IOMMU
- search for IOMMU relevant strings with AMIBCP with some founds ( only in the strings ) pls see attached pictures.
Thats where I stuck now and kindly want to ask for assistance.
Would it be possible for you to integrate the missing feature to this bios ?
Any hints are also higly welcome.
I have attached the modified files and some pictures
Please find the direct download link to the bios package here:

Potentially I have posted this in the wrong forum section so I repost here ( and will delete the old post if this is the right place)
Many thanks in advance and have a nice day,
Peter
