I. Quick Installation Guide:
The system bus speed can be switched at 66, 100 MHz by adjusting SW2. The
user can select the system bus speed for 300-866MHz from DIP Switch SW1.
M The CPU speed must match with the frequency RATIO. It will cause
system hanging up if the frequency RATIO is higher than CPU's.

« Note: We don’t recommend you to set up your system speed to
75,83,112,124,133,140 or 150MHz 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,
133,140 or 150MHz properly will depend on your hardware
configurations: CPU, SDRAM, Cards, etc.
