You didn't state the model number, unless that is it in the problem heading, STAX2517C2.
IF, this is the Model Number of the Northgate Desktop PC, it is supposed to come with a Foxconn/Winfast K7S741MG-6L motherboard,http://www.ebay.com/itm/STAX2517C2-Winfast-Foxconn-AMD-Motherboard-K7S741MG-6L-/380384605182
Click on the photo with SOLD across it. On the next page scroll it down.
There is a main view shown, and separate views under it.
In the separate views, click on the third one from the Left.http://www.motherboards.org/imageview.html?i=/images/mobot/motherboards/8286.jpg
Looks like the Front Panel header on the motherboard, is an 9-pin unit.
(Down by the round CMOS battery, black plastic rectangular header, 9-pins.
In the photo it is down to the Bottom/left corner )
[ The front of your computer is the Front Panel.
The area of contact pins on the motherboard, that the main wires from the Front Panel go to, is the Front Panel header.
May be an abbreviation silk-screened on the motherboard next to it.
F PANEL 1, or FRP1, or FP1 ]
Motherboard sitting in your computer case, the Front Panel header is sitting Horizontal, and parallel to the bottom edge of the motherboard.
There are two rows of pins.
4 across the Top row; 5 across the Bottom row.
The best method is to take an LED light with two wires, and touch two contact pins at a time.
I would go across the Top row first.
Start with the first two pins. Then the second two pins.
When you touch the correct two pins, the Power Supply will come on.
(So will the computer)
You now know that this is the two pins for the Power On switch.
Computer running do not touch the two pins again.
Now touch two other pins.
When the LED light blinks, you know you have the HarDDrive activity LED pins.
If the LED stays on you have the Power On LED pins.
If the computer restarts you know you have the Restart switch pins.
This is what I have that seems to be close, for a Front Panel header pinout for your motherboard.
HOWEVER, I would like you to connect the two pins to the Power On switch first. Just those two.
If these are correct there is a 99 percent chance the others are too.
A) Using an LED light will not harm your motherboard. If the computer isn't running, (Power Supply not on), then you will not be touching any 'live' pins on the motherboard.
Just make a brief contact, with the wires to each set of 2 pins. The Power On switch is a Momentary Contact Switch.
Pinout I have;
Looking at the Front Panel header - Top row;
Starting at the Left side, coming across to the Right side;
Pins 2, 4, 6, and 8. Blank spot -> No pin.
Starting on the Left side, coming across to the Right side;
Pins 1, 3, 5, 7, and 9.
A) Pins 2 and 4 are for the Power On LED (Light)
Pin 2 is for the Positive ( + ) wire.
If the PWR ON LED is dim when the computer is on, switch the wires around.
B) Pins 6 and 8 are for the Power On switch.
C) No pin 10. Blank spot.
D) Pins 1 and 3 are for the HarDDrive activity LED (Light)
Pin 1 is for the Positive ( + ) wire.
If the HDD LED is dim when the harddrive is active, switch the wires around.
E) Pins 5 and 7 are for a Reset switch, IF a Reset switch is used.
F) Pin 9 is N/C. Not Connected. Probably 5 Volts (DC), and reserved for the factory.
Would appreciate hearing back if this pinout worked for your motherboard.
Also would appreciate if it did not work, and you found out, how about posting back on that also?
A LOT of people would appreciate this information.
