The specific steps to disable kernel DMA will vary for every different manufacturer BIOS. Please refer to the manufacturer's user manual for your specific PC if available, as that will usually be the best reference. Otherwise, the general steps to do so are as shown below:
- Boot into BIOS, this can be done by rebooting your PC and press F2/Delete, it will show up on your screen before Windows comes up.
- Then if you are able to boot in, you will land on the BIOS page. Usually, this DMA setting will be under Security Tab.
- Below is an example image. It might look different on your screen. Choose the Kernel DMA Protection and then select Disabled.
- Another thing that you can set to Disabled in the BIOS is the Intel Virtualization Technology for I/O (VT- d) if you don't have the option to disable Kernel DMA Protection. (VT-d settings can be found under Advanced CPU Settings)

- Select "Save and Exit" and then reboot your MXI PC.
