A:For Intel CPU: You do not need to do any setting. When you install CPU at the first time, all that you need to do is go to BIOS and "Load setup defaults", then the system will auto detect the correct CPU FSB.

For K7VT2 and K7VM2: There is a FSB_SEL jumper on the motherboard .
FSB 100Mhz set 2-3
FSB 133Mhz set 1-2
