Doug, On the back of a typical IDE drive, between the power and data connectors, there is a double-row configuration header; it looks just like the data connector, except it typically has only four sets of pins. One or more shorting jumpers are plugged onto the pins in order to configure the drive as master, slave, or cable-select. And one pair of jumpers provides a 32Gbyte clip, so that the BIOS thinks that the drive is smaller than it really is. The jumper doesn't change the physical characteristics of the drive; it simply deceives the BIOS. Somewhere on the label of the drive, the manufacturer should have provided a diagram or a table showing which pins to jumper for the various configuration options. If not, then you need to check the web site of the manufacturer for a diagram or table. When installed, a jumper "shorts" or "bridges" a pair of pins. The jumper has a plastic body and a gold-plated brass insert; it is about 6 mm long, 2.5 mm wide, and 5 mm high. A new drive typically ships with at least two jumpers. Sometimes an extra pair of dummy pins provides a place to "park" a spare jumper. The same type of jumper is used on the back of CD-ROM drives. So if you need a jumper and there is not a spare jumper on the drive, look around for an old disk drive or an old CD-ROM drive.
