EP-BXBS Appendix Appendix D CPU Clock Frequency selection in BIOS There is a special function available in the BIOS to adjust the CPU bus frequency. This allows the external clock to be modified depending upon what FSB has been selected. For more information about selecting the FSB please see page 3-4. Once you know what FSB is being used (66 or 100MHz) then it can be modified as follows: 66MHz FSB options: 66.8 (default), 68.5, 75, and 83MHz. 100MHz FSB options: 100 (default), 103, 112, and 133MHz.
