The steps to downgrade a BIOS to an older version are exactly the same as for upgrading to a newer version.

Note : Enabling "IOMMU Mode" will take 64MB of RAM.All BIOS updates for Intel® Desktop Boards were removed from Download Center on November 22, 2019. If the server is a 64-bit OS and virtual machines to which you pass PCI devices are also in 64 bits, this option will not serve you.

This option is different from the "IOMMU" option and allows you (as shown in the image) to redirect 32 bits I/O to 64 bits I/O. Then, if your motherboard supports it, you will find the IOMMU option in : Advanced -> North Bridge.įinally, it is possible that an "IOMMU Mode" option is also available. In the Asus UEFI BIOS, this feature is in "Advanced -> CPU configuration" and is called SVM (Secure Virtual Machine), or AMD-V or AMD Virtualization. If it is not already done, enable the SVM virtualization.This is the virtualization technology that everyone knows. If you have an AMD CPU, the IOMMU technology will be called IOMMU. Note that you will probably also need to enable the "Intel Virtualization Technology" option (which corresponds to the Intel VT-x) since you need the Intel VT-d feature.
Select "Enabled" and validate by pressing Enter. To enable the Intel VT-d in this BIOS, go to the "Advanced" tab, select the "VT-d" option and press Enter.
This is particularly the case with the "MSI GP62 6QE Leopard Pro" laptop PC. If you have a fairly powerful and especially recent MSI laptop PC, it's possible that it supports input/output virtualization (Intel VT-d).
Then, if your motherboard supports it, you will find the "VT-d" option that matches IOMMU in "Advanced -> System Agent Configuration" or "Advanced -> North Bridge". Note : You can find other interfaces in our tutorial : Enable virtualization (Intel VT-x / AMD-V) In the Asus UEFI BIOS, this feature is in "Advanced -> CPU configuration" and is named "Intel Virtualization Technology". This is the virtualization technology that everyone knows. If it is not already done, enable "Intel VT-x" virtualization feature. Then, click on the "Back" button at the top left to return to the menu and go to : System Agent Configuration.Įnable the "Memory Remap Feature" setting that corresponds to the Intel VT-d / IOMMU. Here, check that the "Intel Virtualization Technology" setting is enabled. Once in BIOS advanced mode, go to the "Advanced" section (at the top) and click on "CPU Configuration". To get started, enable processor virtualization (Intel-VT-x) in the advanced settings of your BIOS. If you have an Intel CPU, the IOMMU technology is called "Intel VT-d". IOMMU is used in particular by the " PCI passthrough" feature of XenServer. isolate I/O and memory accesses to prevent DMA attacks on the physical server hardware.to pass a PCI device to a HVM (hardware or virtual machine hardware-assisted virtualization) virtual machine.If you have installed a virtualization server and want to "pass" the graphics card or other PCI device to a virtual machine running on your hypervisor (virtualization server), you should enable IOMMU (or VT-d for Intel) in the motherboard BIOS of your server.
