Before we get started Make sure 7zip is installed on your computer. It is free and it works well... so you should have it allready anyways.
1. First go ahead and grab one of the MultiOEM Addons. I am gonna demonstrate using MultiOEM_ACER_ADDON.7z.
2. Right click and choose "7zip>Extract Files..." then click "OK".
3. Now I am gonna list out every directory/file and code. Any areas in RED must be edited to represent your new manufacturers name (Prefferably 8 characters or less).
Any areas in DARK BLUE Represent the CRC32 of the cat file according to the fileset you are adding to this addon.
If you see any GREEN areas then you place a bios string there.
You can add multiple lines to the [SystemData] section. This is useful if there are multiple bios strings you need to use.
