2-5 Connector and Jumper Settings
Connectors are used to link the system board with other parts of the system,
including the power supply, the keyboard, and the various controllers on the front
panel of the system case.
The power supply connector is the last connection to be made while
installing a motherboard. Before connecting the power supply, please make
sure it is not connected to the power source.
All cables are security-proof
PW 1 / 2 (ATX Power Supply Connector):
The power cord leading from the system's power supply to the external power
source must be the very last part connected when assembling a system. The ATX
power supply provides a single 20-pin connector interface, which incorporates
st/-5V, +/-12V, optional 3.3V and Soft-power signals. The Soft-power
signal, a 5V trickle supply is continuously supplied when AC power is available.
When the system is in the Soft-Off mode, this trickle supply maintains the system in
it's minimum power state.
Software Power-Off Control
This motherboard can be powered down using Windows® 9x Software Power-Off
function. To power down your computer, click the START button on the Windows®
9x task bar. Select “Shut down the computer” and the system turns off. The message
“It is now safe to turn off your computer” will not be shown when using this
function.

Power-On By Modem:
While in Soft-Off state, if an external modem ring-up signal occurs, the system
wakes up and can be remotely accessed. You may enable this function in BIOS's
Power Management Setup menu. (See section
3
).
Blinking LED in Suspend Mode:
While in Suspend mode, the LED light on the front panel of your computer will
flash. Suspend mode is entered by pressing the Override Power Button, pushing the
Green button on your ATX case, or enabling the Power Management and Suspend
Mode options in BIOS's Power Management menu. (See section
3
).
Poly-fuse Over Current Protection:
The poly-fuse protects the system from dangerous voltages that the system might be
exposed to via the keyboard or USB connector. In case of such exposure, the
poly-fuse will immediately be disconnected from the circuit, just like a normal fuse.
After being disconnected for a certain period of time, the poly-fuse will return to its
normal state. Then the keyboard or USB connector can function properly again.
Unlike conventional fuses, the poly-fuse does not have to be replaced, relieving the
user wasted time and inconvenience.
FD1 (Floppy Connector)
This motherboard provides a standard floppy disk drive connector that supports
360K, 720K, 1.2M, 1.44M and 2.88M floppy disk types. This connector is used to
connect 34 pins of Floppy drive cable.
