I. Quick Installation Guide :
CPU SPEED SETUP
The system bus speed is set to 100MHz. The user can select the system bus
speed and change the DIP SWITCH (SW1) selection to set up the CPU
speed for 400 - 650MHz processor.
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.
SW1: (ON: m / OFF: 5 )
Ratio 1234 Clk 5 6 7 8 PCI Clk
X4 O O XO100 X X X X 33
X4.5 XOXO112 X X OX37.5
X5 OX X O124 XO O X41.3
X5.5 XXXO133 XOX X 44.3
X6 OOOX133 O O O X33
X6.5 XO O X
« Note: We don’t recommend you to setup your system speed to 112, 124
or 133MHz because these frequencies are not the standard
specifications for CPU, Chipset and most of the peripherals.
Whether your system can run under 112, 124 or 133MHz properly
will depend on your hardware configurations: CPU, SDRAM,
Cards, etc.
