Jumper Description
Pins 1-2
jumpered
(Normal
mode) 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.
Pins 2-3
jumpered
(Maintenance
mode) Starting the system with the jumper set in Maintenance mode automatically
starts the system setup program, adds the Maintenance option to the
menu bar, and displays the Maintenance screen. This screen provides
the following option.
NOTICE: Entering Maintenance mode returns all settings in the
system setup program to their defaults. Dell strongly recommends
that you record or print all current settings before entering this
mode so that you can correct them when the system is reset to
