BIOS

My bios version is 7C94v1E, With this bios you just need to disable secure boot.

You can download all bios here.

Do not use biso after 7C94v1E, above 4G is turned on by default and cannot be changed. The system will fail to boot.

AMD BIOS Settings

I use npci=0x3000 instead of enable above 4G
