This jumper allows you to select your host CPU frequency. For 133/166MHz FSB, please set the pin to 1-2; and for 100MHz
FSB, please set it to pin 2-3. Generally speaking, if you are not overclockers, we recommend you to set it to the default setting.
Additionally, this motherboard also provides “1MHz Stepping Adjustment” feature for overclockers to adjust CPU FSB
frequency via BIOS setup program. The adjustment range is 100~200MHz. If you fix the CPU FSB frequency by JP21, the
“1MHz Stepping Adjustment” range will be changed and following the JP21 setting.
