Changing Jumper Settings
Below is a list of actions to take to change the jumper setting for the Clear CMOS
option. Most of the actions below refer to all of the jumpers that you might wish to
change. Any differences for the changing of each jumper are listed in a table.
Clearing the CMOS
NOTE
:
Clearing the CMOS will load the Manufacture default settings in to the NVRAM.
Figure 3
shows the location of the CMOS clear header on the motherboard. The
jumper is usually set to pins 1-2 (Preserve contents of CMOS).
Figure 8
NOTE:
A jumper is a small plastic conductor that slips over two header pins. To change a setting,
remove the jumper from the pins and slide it onto the new pins for the desired setting.
!
CAUTION!
To avoid bending or breaking pins, use caution when removing or installing a
jumper.
This procedure assumes that the motherboard is installed in the computer and the
configuration header (J2J1) has the jumper’s set to the defaults.
