This setting should be located in AMD CBS menu just above the PCIe ARI Support setting. Let me know if this helps. If you are wondering what all this is for: IOMMU lets you pass through an entire graphics card and USB controller to a virtual machine. If the BIOS flashing didn't succeed, the Gigabyte motherboard will probably choose the installed fallback BIOS What are the pros and cons of enabling these in the BIOS ? I believe ARI is a must, and ACS is desirable or also must for SR-IOV, so I am asking particularly when SR-IOV is not used (but passthrough is used). Doing reading and digging to better understand about IOMMU, PCIe ACS, VFIO, etc. 1 PCI bridge [0604]: Advanced Micro Devices, Inc. Post #4 of this thread contains that BIOS. May 25, 2020 436 260 63.
