I am looking for the “Control Iommu Pre-boot Behavior” or “Pre-boot DMA Protection” option in BIOS. Where can I locate this option in the BIOS interface?
The option name varies across different platforms. Please refer to the following screenshots to identify the correct option and its location in the BIOS menu.
Intel platform
● W680 / Z690 series
[BIOS SETUP] – [Advanced] – [Chipset Configuration]
● W880 / Z890 / W790 seriess
[BIOS SETUP] – [Advanced] – [Chipset Configuration]
Note:
- Please first update BIOS to the latest version to obtain the option on the above platforms.
- Users can enable the option if encounter security related problems.
