2.4 66/100MHz System Configuration
Jumper 1 (JP1) allows you to set the FSB (Front Side Bus) to either 66 or 100MHz configuration.
When you set the FSB to 66MHz, you can select a system bus frequency from 66MHz to
83.3MHz through “CPU Host Clock (CPU/PCI)” of “Chipset Features Setup” in BIOS Setup
(Please refer to page 26). When you set the FSB to 100MHz, you can select a system bus
frequency from 100MHz to 150MHz through “CPU Host Clock (CPU/PCI)” of “Chipset Features
Setup” in BIOS Setup (Please refer to page 26).
NOTE:If you are not familar with this feature, we recommend you set this jumper to “AUTO”

2.5 CPU Internal Frequency Ratio Setting
Switch 1 (SW1) is for adjusting the CPU internal frequency ratio. The frequency ratio is shown
in the table overleaf. The internal frequency can be calculated by the following formula:
CPU internal frequency = frequency ratio x system bus frequency *
* System bus frequency is set in “CPU Host Clock (CPU/PCI)” of “Chipset Features Setup” in
BIOS Setup (Please refer to page 26).
NOTE: Because Intel has locked the frequency ratio for new CPUs, setting SW1 to
adjust the frequency ratio is useless. However, it is effective for old version CPUs.
