2-8.2 Jp2: CPU Clock Select
1. Before setting the CPU clock by Jp2, read
the Identification Legend on the CPU, find
the Max FSB and divide it by two. The
result is the default CPU clock.

If a pin-header (of 2 or more pins) is
designed in such a way that its pins
can be closed or linked together to
set up a specific function, this header
is called a jumper in this manual.
A 3-pin Jumper
The conductor inside the cap
links two header-pins together.
• A Jumper is usually but not necessarily given a “JpX” legend.

• Do not remove any jumper cap when power is on. Always
make sure the power is off before changing any jumper settings.
Otherwise, mainboard could be damaged.
2-8.1 How to tackle the Jumpers:
• In the Jumper setting diagram, all jumper pins covered with
black marks stand for closed pins with jumper cap.

2. Setting Jp2 1-2 closed is for 100/133MHz
CPU.
3. Setting Jp2 2-3 closed is for 166/200MHz
CPU, 100/133MHz CPU will fail to boot
herewith.
4. If 100/133MHz CPU fails to boot system ,
you should excute the nVIDIA-Boot-Failure-
Restart Procedure to reboot system.
