The front of your computer is the Front Panel.
The area of pins on the motherboard, that the main cables, (Wires), go to, is the Front Panel header.
Motherboard as installed in computer case;
Processor to the top, Ram Memory slots to the right, white PCI slots to the bottom;
The Front Panel header is located at the Bottom/Right corner.
PANEL1.
Two rows of pins.
(To the left of it is the front panel USB header. USB56. Looks very similar)
Doesn't show numbering for the pins. (Contact pins)
I'm going to number them for easier orientation
The pins across the TOP are numbered ODD.
Starting on the LEFT side going towards the Right;
Pins 1, 3, 5, and 7. There is NO Pin 9.
The pins across the BOTTOM are numbered EVEN.
Starting on the LEFT side going towards the Right;
Pins 2, 4, 6, 8, and 10.
A) Pins 1 and 3 are for the Power On LED (Light)
Pin 1 is for the Positive ( + ) wire.
If the LED is dim when the computer is on, switch the wires around.
B) Pins 5 and 7 are for the Power On switch.
C) Pins 2 and 4 are for the HarDDrive activity LED (Light)
May be marked on the wires as HDD, or IDE.
Pin 2 is for the Positive ( + ) wire.
If the harddrive activity LED is dim when the harddrive is active, switch the wires around.
D) Pins 6 and 8 are for a Reset switch, IF a Reset switch is used.
E) Pin 10 is N/C
Not Connected. (Probably a +5 Volt point for the factory to use)
