I would like you to left-click on the top file.
Click right on - Product Guide - PDF, in blue.

(File name underneath it is -
File Name: D845GVSR_Product Guide_English.pdf )

May take up to 30 seconds, before you see the first page.
(You will be staring at a blank screen until the first page comes up. The file is downloading in the background)

Took 5 seconds before I saw the first page, and an additional 12 to fully download, using a medium speed DSL connection.

The Front Panel header on the mobo is shown on Page 31. (C on the illustration. J9G1 on the mobo)

The Front Panel connections are on Page 32.

Barring that you cannot download this PDF file, or do not understand the manual, I will detail the Front Panel header connections.

Orienting the motherboard so we are both looking at it the same way;

The Processor is at the top, the ram memory slots are to the right side of the mobo, and the white PCI slots are to the bottom.

There are three PCI slots. The one closest to the Processor is PCI 1.
The one closest to the edge of the mobo is PCI 3.

To the far right of PCI 3 is the Front Panel header.
It's the header located closest to the Right side of the mobo, and the bottom edge, and is directly below the
CMOS battery.

There are two rows of pins.
Four across the top, Five across the bottom.

The top row of pins are numbered Evenly.
The bottom row of pins are numbered Odd.

Starting from the Left side of the mobo, going to the right, on the Top row,

Pins 2, 4, 6, and 8. (There is No 10)

Starting from the Left side of the mobo, going to the right, on the Bottom row,

Pins 1, 3, 5, 7, and 9.

A) Pins 1 and 3 are for the Harddrive Activity LED
If you have a wire with a + sign on it (Positive) it goes to Pin 1.

B) Pins 2 and 4 are for the Power On LED.
(Pin 2 to the Green LED lamp, Pin 4 to the Yellow LED lamp, if applicable with your computer)

C) Pins 5 and 7 are for a Reset switch. (If applicable)
(Pin 5 is Ground)

D) Pins 6 and 8 are for the Power On switch.
(Pin 8 is Ground)

E) Pin 9 is for the +5 Volt power.
