The illustration shows how jumpers are setup. When
the jumper cap is placed on pins, the jumper is
"SHORT". If no jumper cap is placed on the pins,
the jumper is "OPEN". The illustration shows a 3-pin
jumper whose pin1 and pin2 are "SHORT" when
jumper cap is placed on these 2 pins.

Note: The setting of the CPU front side bus frequency of this motherboard is by means of the
adjustment of jumper-setting. You must set the FSB jumper according to your AMD CPU
before you use the "Manual" option as the FSB setting in BIOS setup to perform over
clocking. Please follow the figures above to set the CPU front side bus frequency.
