I've been where you are and I did a lot of research in addition to contacting Geeks.com from whom I purchased the mobo.

Here is the HP link to the drivers. This motherboard is for a Compaq Evo D510:
http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareIndex.jsp?lang=en&cc=us&prodNameId=97128&prodTypeId=12454&prodSeriesId=316510&swLang=8&taskId=135&swEnvOID=1093#120

The front panel, audio, USB pin locations can be found as the other posts have indicated. Download the manual that was provided on one of the posts.

Motherboard User Manual For SiS965L?


SiS965L is a chipset designation, not a motherboard model number. That said, most motherboards do label the header pins for the front panel connections on the motherboard, though they are a bit small and sometimes are not adjacent to the pins themselves. The Power Switch and Reset Switch pins are not polarized, and when you determine which they are, the connector plug can be installed on them either way. The Power LED and HDD LEDs ARE polarized. The positive pin is marked with a "+" sign and the Green wore of the Power LED and the Red wire of the HDD LED must be on the "+" terminal.

How to re-wire a Compaq Presario SR2150NX Case power Switch


The plastic front of your desktop computer is the Front Panel.

The area of contact pins on the motherboard, that the wires from the Front Panel go to, is the Front Panel header.

F_PANEL_1

The Front Panel header contains connections for the Power On switch, Power On LED light, HarDDrive activity LED light, and so on.

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00864922&tmp_task=prodinfoCategory&cc=us&dlc=en&lang=en&lc=en&product=3339274

(Look at the motherboard photo. The Front Panel header is at the bottom right. Scroll down for the motherboard illustration )

There are 9 contact pins.
4 across the Top row, and 5 across the Bottom row.

The four pins across the Top row are numbered EVEN.

From the Left side going towards the Right side;
Pins 2, 4, 6, and 8. There is NO pin 10, just a blank spot.

The five pins across the Bottom row are numbered ODD.
Pins 1, 3, 5, 7, and 9.

A) Pins 2 and 4 are for the Power On switch

B) Pins 6 and 8 are for the Power On LED

(LED is dim when the computer is on? Switch the wires around )

C) Pins 1 and 3 are for the HarDDrive activity LED

(LED is dim when the harddrive is operating? Switch the wires around)

D) Pins 5 and 7 are for a Reset switch, IF a Reset switch is used.

How to know which wires are for the Power On switch, Power On LED, and HDD LED?

Follow the wires into the Front Panel. Remove the Front Panel, and follow them.
(Need guidance removing the Front Panel post in a Comment )

For additional questions please post in a Comment.
