Hi, I have a hp pavilion 550-100nl with bios A0.05 Rev.A, is there a way to enable IOMMU mode if supported?

you need to check in the bios, the bios are rarely fully described in the support pages

2. Enable IOMMU for AMD processors

If you have an AMD processor, the IOMMU technology will have the name IOMMU.

If you haven't already, enable processor virtualization named SVM. This is the virtualization technology that everyone knows.
In the Asus UEFI BIOSes, this function is in "Advanced -> CPU configuration" and is named SVM (Secure virtual machine), or AMD-V or AMD Virtualization.

Thank you for replying, unfortunately the Foxconn Orchid3 motherboard bios is very poor! virtualization is enabled but I couldn't find anything on IOMMU
