I. Quick Installation Guide :
CPU SPEED SETUP
The system bus fr equency can be switched at 66MHz, 100MHz and 133 MHz by
adjusting DIP SW2. The CPU frequen cy ratio can be switched from X3 to X 9.5
by adjusting DIP SW1. The user can set up CPU speed for 300-733MHz
processors by adjusting SW1 and SW2 properly.
The CPU speed must match with the frequency RATIO. It will cause
0000
system han g ing up if the frequency RATIO is higher than CPU's.

Note: Please set the CPU host frequency in accordance with your
processor’s specificat ions. We don’t recommend you to set the
system bus frequency over the CPU’s spe c ification because
these specific bus frequencies are not the standar d
specifications for CP U, chipset and most of the peripherals.
Whether your system can run under these specific bus
frequencies properly will depend on your hardware
configurations, including CPU, Chipsets, SDRAM,
Cards….etc.
