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 500 – 1G Hz 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.

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, Chipset 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. 1.
