Explanation of
Jumpers
To modify the operation of the moth-
erboard, jumpers can be used to
choose between optional settings.
Jumpers create shorts between two
pins to change the function of the
connector. Pin 1 is identified with a
square solder pad on the printed cir-
cuit board. See the motherboard
layout pages for jumper locations.

Changing the CPU
Speed
Changing the CPU speed is enabled
by software control in BIOS (see
CPU Speed on page 4-10 and CPU
Clock Frequency on page 4-12). The
CPU Speed setting will show you the
actual CPU speed for each FSB
speed option selected. The CPU
Clock Frequency setting will show
you additional FSB speed options.
The FSB speed is set with JP11.
See Table 2-16 for jumper settings.
Note: If the system does not reboot
after changing the CPU speed, either
1) clear CMOS and reboot or 2) en-
able the CPU Safe Mode (below),
change to the correct speed, then
disable the CPU Safe Mode again.
