BIOS Configuration

==============================

IMPORTANT NOTE: The downloadable BIOS config file is for BIOS version F9. If you're using another BIOS version, you should set the values manually.

==============================

NOTES

I've taken pictures of the important screens of the BIOS. Settings that I've explicitly called out below the associated pictures are important. You can also refer to the guide.

Shortcut

The easiest way to make sure you've got your BIOS configured correctly is to just download my BIOS profile, throw it on a FAT32-formatted USB, and then "Load Profile" on the "Boot" page of the BIOS. You still need to update your BIOS to firmware version F9 manually before you do this!. This also does not affect all settings, so please read through and make sure everything lines up manually.

If you have an older version of the BIOS, version F9i, then you will still need to set the values manually. Check the images folder and OpenCore guide for BIOS settings.
