Installation Instructions
Jumper Settings
Jumpers are located on the mainboard, they represent, clear CMOS jumper JCC, enable
keyboard password power-on function jumper JKB, and enable/disable onboard audio
jumper JSD etc. Pin 1 for all jumpers are located on the side with a thick white line ( Pin1→
), referring to the mainboard's silkscreen. Jumpers with three pins will be
shown as
to represent pin1 & pin2 ("1-2") connected and
pin2 & pin3 ("2-3") connected. For default jumper settings, please refer to the following

Overclocking Jumper Setting (JFS0, JFS1)
Jumpers labeled JFS0 and JFS1 are located on the mainboard providing users with CPU
overclocking feature. The host bus speed can be set as 66/100/133MHz or AUTO. Refer
to the chart below for the location of these jumpers, and the table for information on how
to set them.
If CPU FSB is set as Auto (default), the system detects the CPU FSB (front side bus)
automatically. If CPU FSB is set as 100MHz, the system will run at 100MHz even if a
processor with 66MHz or 133MHz FSB is installed. Setting up to 133MHz using proces-
sors with 100MHz bus speed is also supported. However, whether or not the system can
be overclocked depends on your processor's capability. Whether the processor is bus
ratio locked or unlocked should also be taken into account. For bus ratio unlocked proces-
sor, this overclocking feature can be implemented by setting CPU FSB as 100/133MHz,
meanwhile adjusting the bus ratio (multiplier) lower in "CPU SpeedEasy Setup" in AWARD
BIOS CMOS Setup. You can also adjust the CPU frequency by running StepEasy. We do
not guarantee the overclocking system will be stable.
