Configuring the System 3-39
Changing a System Board Jumper Setting
Change a system board jumper setting using these guidelines.
See the previous sections for specific jumper settings.
Note:
NEC CSD recommends using needle-
nose pliers to move a jumper.
1. Record your customized CMOS settings before changing
the jumpers that affect the CMOS Setup Utility. See “The
CMOS Setup Utility” in this chapter.
!
WARNING
The system power must be off before you
change a jumper setting.
2. Remove the cover(s).
In a small desktop or desktop system, see “Removing
the Small Desktop or Desktop Cover.”
In a minitower system, see “Removing the Minitower
Side Covers.”
3. Locate the jumper block on the system board (see
“System Board Configuration Settings”).
4. Move the jumper to the new setting.
!
CAUTION
If you are clearing your CMOS settings, you must
make this change while the power cord is
unplugged (since the standby power for the
PIIXE4 chipset comes from the power supply).
Let the system rest for five seconds for the power
to clear before moving the jumper back.
