HD-LED
(IDE - Activity LED Connector):
The IDE- activity LED lights up whenever the system reads/writes to the IDE
devices.
FDD1 (Floppy Connector):
The motherboard provides a standard floppy disk drive connector that
supports 360K, 720K, 1.2M, 1.44M and 2.88M floppy disk types. It is
connected to a floppy disk drive of 34 pins.
IDE 1/2 (IDE Hard-Disk Connector):
The motherboard has a 32-bit Enhanced PCI IDE and
Ultra ATA66/100/133 controller that provides PIO
mode 0~4, Bus Master, and Ultra ATA66/100/133
function. This connector is used for connecting 40 pins of ATAPI devices.
IDE 1 only connects two IDE devices. (

FAN1/2 (CPU/System Connectors):
The board's hardware management is able to detect the CPU
and system fan speed in rpm (revolutions per minute). The
wiring and plugging may vary depending on the manufacturer.
On standard fans, the red is positive (+12V), the black is
ground, and the yellow wire is the rotation signal.
JP1 (CMOS Clear Jumper):
There is a CMOS RAM on board that
has a power supply from external
battery to keep the data and system
configuration. To clear the contents of
the CMOS, please follow the steps below.
1. Disconnect the system power supply from the power source.
2. Set the jumper cap at location [2-3] for <5 seconds>, and then set it back to the
default position.
3. Connect the system's power and then start the system.
4. Enter BIOS's CMOS Setup Utility and choose Load Optimized Defaults.
5. Type [Y] and then press [Enter] to continue.
