System Board Configuration Jumpers
Clear CMOS
Jumper (J22)
The
CMOS
memory stores information, such as your computer’s configuration, which is preserved when you turn off your
computer. A jumper placed on pins 1-2 prevents change to the CMOS configuration. This is the default setting. Refer to
“Clearing the CMOS Configuration” on page 33
for information about clearing the CMOS and using this jumper.
Microprocessor
Configuration Jumper
(J23)
This jumper allows the system board to match the speed of the installed processor. You only need to change the
microprocessor configuration jumper if you install a new processor with a different speed to the one that is currently
installed. Refer to
“Upgrading a Processor” on page 46
for information about installing a processor upgrade and changing
the jumper settings.
Note
PCI expansion card slots are generally white plastic grooves.
ISA expansion card slots are generally black plastic grooves lined with silver.
