The Front Panel header, and the 1st jumper block?[ The plastic front of your 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. In this case there are two headers ]If so I got yer back, eng_m_yehia.JFP1 is to the right of the BIOS chipset.

(IF, a Reset switch is used. No Reset button? No Reset switch )4) HarDDrive activity LED light connects. Looking at the motherboard installed in the computer;Processor to the top, Ram Memory to the right, white PCI slots (3) at the bottom.The JFP1 header is at the right bottom edge of the motherboard, to the right of the BIOS chipset, and is situated Vertically.Has two columns of contact pins. Starting at the BOTTOM Right side, going UP;Pins 1, 3, 5, 7, and 9.Starting at the BOTTOM Left side, going UP;Pins 2, 4, 6, and 8. There is NO Pin 10, just a blank spot.A) Pins 1 and 3 are for the HarDDrive activity LED light.Pin 1 is for the Positive ( + ) wire. IF the HDD activity LED is dim, when the harddrive is operating, switch the wires around.B) Pins 5 and 7 are for the Reset switch. IF, a Reset switch is used.C) Pin 9 is N/C. Not Connected. Not used. This is for the factory.D) Pins 2 and 4 are for the Power On LED light.Pin 2 is for the Positive ( + ) wire. If the LED is dim when the computer is on, switch the wires around.E) Pins 6 and 8 are for the Power On switch.A note about the Power On LED light, and wires.For a Power On LED light that has TWO wires, use JFP1.If it has THREE wires, use JFP2.Some Power On LED lights had/have dual colors. In the older computers it usually was Green, and Yellow.Yellow meant you were in Normal mode, and Green meant Turbo mode.A bunch of cr@p really. When in turbo mode, the computer was operating at it's fullest. In the other mode, it was being slowed down, below the normal output of the computer.For additional questions please post in a Comment.Regards,joecoolvette
