To allow IOMMU in your BIOS, you will have to entry the BIOS settings. This may be completed by urgent a particular key in the course of the boot course of. The important thing that it’s essential to press will differ relying in your motherboard. After you have accessed the BIOS settings, you will have to seek out the IOMMU settings. These settings will even differ relying in your motherboard. After you have discovered the IOMMU settings, you will have to allow them. After you have enabled IOMMU, you will have to avoid wasting your adjustments and exit the BIOS settings. Your pc will then restart and IOMMU shall be enabled.
After you may have enabled IOMMU in your BIOS, you will have to configure your working system to make use of it. This may be completed by enhancing the grub.cfg file. The grub.cfg file is positioned within the /boot/grub listing. After you have edited the grub.cfg file, you will have to avoid wasting your adjustments and restart your pc. Your pc will then boot into the working system and IOMMU shall be enabled.
Finding IOMMU Choices

Search for an possibility named “IOMMU” or “VT-d” (for Intel processors) or “AMD-Vi” (for AMD processors).
4. Allow IOMMU
Relying in your BIOS interface, you might have to modify the IOMMU choice to “Enabled” or verify a field labeled “Allow IOMMU.” Listed below are detailed steps for enabling IOMMU on completely different BIOS interfaces:
| BIOS Interface | IOMMU Allow Steps |
|---|---|
| AMI BIOS |
Navigate to “Superior > CPU Configuration” |
| Award BIOS |
Navigate to “Superior > Chipset Options” |
| Phoenix BIOS |
Navigate to “Superior > Northbridge” |
Saving BIOS Modifications
Restarting the Pc
After you have made the required adjustments to the BIOS settings, it’s essential to save them and restart the pc. To do that, press the “F10” key to avoid wasting the adjustments and exit the BIOS. The pc will then restart with the brand new BIOS settings.
Utilizing the BIOS Menu
You may also save the BIOS adjustments utilizing the BIOS menu. To do that, navigate to the “Exit” menu and choose the “Save Modifications and Exit” possibility. The pc will then restart with the brand new BIOS settings.
Utilizing the Reset Button
In case you are unable to avoid wasting the BIOS adjustments utilizing the keyboard or the BIOS menu, you need to use the reset button on the motherboard. To do that, find the reset button on the motherboard and press it for a number of seconds. The pc will then restart with the default BIOS settings.
Utilizing a USB Flash Drive
In case you have a USB flash drive, you need to use it to avoid wasting the BIOS adjustments. To do that, format the USB flash drive as FAT32 and replica the BIOS replace file to the drive. Then, insert the USB flash drive into the pc and restart the pc. The pc will then boot from the USB flash drive and replace the BIOS.
Utilizing a CD or DVD
In case you have a CD or DVD drive, you need to use it to avoid wasting the BIOS adjustments. To do that, burn the BIOS replace file to a CD or DVD. Then, insert the CD or DVD into the pc and restart the pc. The pc will then boot from the CD or DVD and replace the BIOS.
