The JP4 Jumper allows you to set the FSB (Front Side Bus) to 66/100/133MHz configuration.
When the Jumper is set to “Auto”, the freqency range depends on your CPU type. When you set
the FSB to 66MHz, you can select a system bus frequency from 66MHz to 99MHz through “CPU
Host/PCI Clock” of “Frequency/Voltage Control” in the BIOS Setup menu. When you set the
FSB to 100MHz, you can select a system bus frequency from 100MHz to 132MHz . When you
set the FSB to 133MHz, you can select a system bus frequency from 133MHz to 166MHz .
