In Normal mode, system setup settings and installed passwords are
retained when the system starts up. In this mode, an automatic recovery is
attempted if the BIOS detects that any of its main blocks are corrupted.

mode)
Starting the system with the jumper set in Maintenance mode automatically
starts the system setup program, adds the
