IDE drives contain an integral disk controller which is the equivalent
of a normal disk controller.  Most can support 2 drives and most systems
only support one controller, so you set your second drive to "slave" to
disable its controller (that you had to buy since it's integral) and use
the controller on the "master" drive instead.
