For most systems, BIOS files must be placed in the

A few systems need the bios files to be placed in subfolders. Refer to the individual system wiki page for detailed information about BIOS placement.

BIOS files are copyrighted and are therefore not included with Retrobat.
We can not legally distribute them, so you will need to supply your own.
