Shown above is the front panel connector on a motherboard, as well as the IDE connectors. Most motherboards have two IDE connectors, which allow two drives to be attached to each connector. One drive is set to master and the other drive is set to slave by using a jumper that is normally located on the back of the drive. This allows a total of four IDE devices, (or drives), to be attached to a typical computer. The motherboard usually also has a floppy connector that supports one or two floppy drives. If a person needs to add additional drives, he or she must purchase an expansion card with an added IDE connector. The front panel connector is simply the location on the motherboard where you attach the front panel wiring. These wires usually include the wiring for the case speaker, hard drive activity lights, computer power on light, reset button, power button, and key lock, (if you have one).
