USER'S MANUAL

1. System power on by PS/2 Mouse: If you are using ATX power
supply, you are able to power on the system by double
clicking the right or left button of your PS/2 Mouse.

2. System power on by Keyboard: If your ATX power supply
supports larger than 720 mA 5V Stand-By current, you can
power on your system by entering password from the
Keyboard after setting the “Keyboard power on” jumper (JP1)
and password in CMOS Setup.

3. Modem Ring-On on COM B.

4. Wake-Up on LAN. (The ATX power supply supports larger
than 600 mA)

5. Support 3 steps ACPI LED selectable.

I. Quick Installation Guide :

CPU SPEED SETUP

The system bus speed can be selectable between 66.6MHz and 100MHz. The
user can select the system bus speed (JP10) and change the DIP SWITCH
(SW) selection to set up the CPU speed for 200 - 633MHz 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.
