the DIP SWITCH (SW1) selection to set up the CPU speed for 233 - 650MHz
processor. The CPU speed must match with the frequency RATIO. It will
cause system hanging up if the frequency RATIO is higher than CPU's.

The CPU is a sensitive electric component and it can be easily
damaged by static electricity, so users must keep it away from
metal surface when the CPU is installed onto mainboard.

We don' t recommend you to setup your system speed to 75, 83,
112, or 133MHz because these frequencies are not the standard
specifications for CPU, Chipset and most of the peripherals.
Whether your system can run under 75, 83, 112 or 133MHz properly
will depend on your hardware configurations: CPU, SDRAM, Cards,
etc.
