This flash BIOS update is for use on 2144 and 2168 ("Axx" in the US) Service Level I Aptiva systems. It installs BIOS level BG2xx0M (BG2US0M on US systems) on 2168 tower models and BO3xx0I (BO3US0I on US systems) on 2144 desktop models.
Executing this file will run a program which creates a bootable floppy. Booting the computer off of the floppy will flash the BIOS, updating it to the most current level. This can solve conflicts with new hardware and software that require information not in the original BIOS in order to interact with the system.
