The Maintenance menu is the first menu displayed. This menu provides options for setting the processor speed and clearing passwords. User and supervisor settings are preserved and used when the computer is rebooted. This mode is for recovering BIOS data. After the computer is powered-on, the BIOS attempts to upgrade or recover the BIOS data from a diskette in the drive.
Continuous beeps indicate failed recovery attempt.
For a full list of beep codes please refer to the technical product specification.
