Phoenix ROM BIOS Ver 1.xx is the first version of PhoenixBIOS, developed by Phoenix Technologies (back then called Phoenix Software Associates) and released in 1984. It is the first mass licensed fully IBM PC compatible BIOS, as other BIOSes at the time were either not fully compatible, or contained copyrighted IBM code, prohibiting their mass licensing.
This version does not include a built-in setup utility as that became a feature a few years later in around 1987 for most computers. For system configuration, a configuration diskette must've been inserted.
