I. Quick Installation Guide:

CPU SPEED SETUP

The default system bus speed is set to 66MHz. The user can change the DIP

SWITCH (SW) selection to set up the CPU speed for 200 - 366MHz processor.

The CPU speed MUST match with the frequency RATIO and external

clock frequency. It will cause system hanging up if the frequency RATIO

and the external clock frequency are higher than that of CPU.

75 MHz 1-2 2-3 1-2

83 MHz 2-3 1-2 2-3

100 MHz 1-2 2-3 2-3

Note: We don’t recommend you to setup your system speed to 75, 83

or 100MHz because these frequencies are not the standard

specifications for CPU, Chipset and most of the peripherals.

Whether your system can run under 75, 83 or 100MHz properly will

depend on your hardware configurations: CPU, SDRAM, Cards,

etc.
