The Ratio of some latest CPUs are fixed by Intel, such as Celeron 366,400...etc. You can ignore the three
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.
2.1.5 CPU FSB Frequency Setting[Red Jumper Caps]
The JFSB jumper provides FSB frequency setting for the CPU. Auto Detect, 66MHz or 100MHz FSB
frequency can be selected with this jumper. The 100MHz FSB frequency setting is over specification
operation for 66MHz FSB CPU. The over specification operation is not recommended. This jumper is
supported from PCB REV:1.02 .
