Aptiva BIOS Updates
MFLASH

This flash BIOS update is for use on 2144 and 2168 ("Mxx" in the US) Service Level H Aptiva systems. It installs BIOS level BGOxx1L (BGOUS1L on US systems) on 2168 tower models and BO2xx0W (BO2US0W 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.

  4. Insert the BIOS update diskette in the diskette drive and start (boot) the system.

  5. A menu will prompt you to choose the desired language.

  6. You will be asked if you would like to change the serial number. Choose (N)o.
