The Ratio of some latest CPUs are fixed by Intel and VIA such as Celeron/ Celeron-II/ Pentium-
III 366, 400, 566... etc and VIA Cyrix III CPU. You can ignore the four jumpers if you have this
CPU on board and it will be auto detected by motherboard. Please check with the CPU
manufacturer or vendor for the CPU Ratio information.
