I. Quick Installation Guide :
CPU SPEED SETUP
The default system bus speed is 66.6MHz. The user can select the system bus speed (JP2, JP3, JP4) and
change the DIP SWITCH (SW) selection to set up the CPU speed for 200 - 633MHz processor.
MMThe CPU speed must match with the frequency RATIO. It will cause system hanging up if the
frequency RATIO is higher than CPU's.
