NOTE:
1. Jumper JP2 is used to select the CPU and SDRAM bus speed. It
can be 66MHz or 100MHz. Jumper JP3 to JP6 is for CPU core
frequency ratio selection.
2. Most Intel Pentium III have fixed CPU core frequency ratio.
You don't really need to set up the JP3~JP6 for the CPU already
fused the core frequency.
3. Overclocking your processor and SDRAM module is not
recommended. There is no guarantee for any over-speed
operation.
