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.

The CPU speed MUST match with the frequency RATIO. It will cause

system hanging up if the frequency RATIO is higher than that of CPU.

1-2-3 OPEN : System Speed is set to 100MHz

6BX

I. Set system speed to 66MHz: JP6 pin 1-2 short will cause

system always run at 66 MHz FSB (Front Side Bus).

II. Set system speed to 100MHz: JP6 pin 1-2-3 open will cause

system always run at 100MHz FSB.

III. Set system speed to Auto: auto detect system speed

(66/100MHz FSB)

There are two ways to set system speed

1. 66MHz (JP6) (1-2 short) or Auto detect (2-3 short)

2. 100MHz (JP6) (1-2-3 open) or Auto detect (2-3 short)
