[. . . ] Quick Installation Guide : CPU SPEED SETUP The system bus speed is selectable between 66. 6MHz and 100 MHz. The user can select the system bus speed (JP6) and change the DIP SWITCH (SW) selection to set up the CPU speed for 200 - 633MHz processor. It will cause system hanging up if the frequency RATIO is higher than that of CPU.
