Jumper Switches
The SBP-205 jumper switches are pre-configured at the factory. Jumpers are used to
configure the processor bus frequency and to clear CMOS contents.
Jumper Switches Overview
The Pentium III processor uses a clock multiplier to match the processor core
frequency with the speed of the processor bus—the speed at which data travels into
and out of the processor. Four jumper switches determine the processor bus
frequency. Another jumper temporarily clears the CMOS contents.
