CPU Speed Setup

The system bus speed is selectable at 66,100,133MHz and Auto. The user can select the
system bus speed (SW1) and change the DIP switch (SW2) selection to set up the CPU speed
for 300 - 733MHz processor.

The CPU speed must match with the frequency ratio. It will cause system hanging up if
the frequency ratio is higher than that of CPU.

Note:

1. If you use 66/100/133 MHz CPU, We recommend you to setup your system speed to
“Auto” value.

2. We don’t recommend you to set up your system speed to 75 , 83 , 112 , 124 , 140 ,150
MHz because these frequencies are not the standard specifications for CPU, Chips et
and most of the peripherals. Whether your system can run under
75 ,83 ,112 ,124 ,140 ,150 MHz properly will depend on your hardware configurations:
CPU, SDRAM, Cards, etc.
