Guide to Installing IDE devices
The vast majority of hard drives sold today for PC computers are IDE or sometimes referred to as ATA drives. That is why we are going to discuss IDE drives.
IDE CHANNELS

So, the normal motherboard has two connectors, one for each channel that data moves through to the motherboard. Each of these channels supports two IDE hard drives, set one as Master and the other as Slave.

These IDE devices are all configured the same as a hard drive. So for now we will concentrate on IDE hard drives. This is a diagram of a Master and Slave configuration on an IDE channel:
