CPU SPEED SETUP
The system bus speed is selectable between 66 / 100 MHz. The user can select
the system bus speed (SW1) and change the DIP SWITCH (SW2) selection to
set up the CPU speed for 233 - 633MHz processor.
Set System Bus Speed

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: 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.
