USER'S MANUAL
1. System power on by PS/2 Mouse: First, enable this function
in CMOS Setup, then you can 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 100~300 mA 5V Stand-By current
(dependent on the specification of keyboard), 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. Support 3 steps ACPI LED selectable.
4. Support Modem Ring-On on COM A , COM B.
5. Support Wake-up on LAN. (Your ATX power supply must
support larger than 720 mA 5V Stand-By current)

CPU SPEED SETUP
The default system bus speed is 66.6MHz. The user can change the DIP
SWITCH (SW) selection to set up the CPU speed for 233 - 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.

«
Note: We don’ t recommend you to setup your system speed to 75,
83 or 100MHz because these frequencies are not the standard
specifications for CPU, Chipset and most of the peripherals.
Whether your system can run under 75, 83 or 100MHz properly
will depend on your hardware configurations: CPU, SDRAM,
Cards, etc.
