1.2 Jumpers
1.2.1 JP1 (CMOS) Clear CMOS jumper
1.2.2 JP3 CPU FSB select jumper (FSB)
This jumper allow the selection of the CPU’s based external frequency. The
CPU “External Frequency” multiplied by the “Frequency Multiple” equals the
CPU’s “Internal Frequency”. Currently, most of the processors have the Fre-
quency Multiple locked, so you only need to select the External Frequency.
Most of the time, you can leave these jumpers on their default setting and the
based external frequency will be determined by CPU automatically.
