Configuring the System Board

The system board contains a CMOS Clear configuration jumper, and two
sets of reserved jumper blocks (do not change).
The CMOS and Non-Volatile RAM (NVRAM) settings are only cleared if
the checksum test returns false. Access to specific setup fields is
controlled by a supervisor password or user password.
The Clear CMOS mode removes the password that is stored in CMOS. No
other parameters are cleared.
✍
The configuration jumpers should never need changing unless otherwise directed by a
technical support or service technician.
!
Before opening the system unit, save and close all open files, exit all open
applications, turn off the power to all attached peripheral devices, shut
down the computer, and unplug the power cord.
