Hi,

I use ASROCK B550 Phantom Gaming 4 ACS with v2.71.
I want to enable ACS to virtualize PCI devices using IOMMU.
But, I cannot find the ACS configuration item in the BIOS.

An existing topics referred to the following.

But, the configuration item does not appear in the BIOS of my motherboard.
I would be happy to get some information from you.

BR, Langur
