CPU SPEED SETUP
The system bus frequency can be switched at 66MHz, 100MHz and 133MHz by
adjusting DIP SW1. The CPU frequency ratio can be switched from X3 to X9.5
by adjusting DIP SW2. The user can set up CPU speed for 300-866MHz
processors by adjusting SW1 and SW2 properly.

The CPU speed must match with the frequency RATIO. It will cause
system hanging up if the frequency RATIO is higher than CPU's.

Note: Please set the CPU host frequency in accordance with your
processor’s specifications. We don’t recommend you to set the
system bus frequency over the CPU’s specification because
these specific bus frequencies are not the standard
specifications for CPU, chipset and most of the peripherals.
Whether your system can run under these specific bus
frequencies properly will depend on your hardware
configurations, including CPU, Chipsets, SDRAM,
Cards….etc.
