Locate the jumpers on the system board you need to
change. To change a jumper setting, use a pair of needle-
nose pliers or your fingers to remove the jumper from its
current location. Position the jumper over the two pins for
the desired setting and press it onto the pins. Be careful
not to bend the pins. Refer to the table “System Board
Jumper Summary” for system board jumper settings.
4.
Replace the side cover and power up the system.
Resetting the CMOS NVRAM
To reset the CMOS NVRAM:
1.
Power off your system. Remove the left side panel as
described in Chapter 4 of this guide.
2.
Move the CMOS Clear jumper from pins 1-2 to pins 2-3.
See the figure “Locating system board jumpers” to locate
this jumper.

Power on the system. Wait for POST to complete and for
the messages “Invalid NVRAM setting by” and “Press F2
to enter Setup” to appear. This automatically reprograms
CMOS and RTC to their default settings.
4.
Power off the system.
5.
Move the CMOS Clear jumper back to pins 1-2.
