Most PC's today use IDE (Integrated Drive Electronics) or EIDE (Enhanced Integrated Drive Electronics) hard drives and CD-ROM drives. IDE drives are generally very easy to install. Most new PC motherboards are equipped with an IDE connector and most newer boards have two.
If your system includes only one IDE controller, the addresses are preset and standard. The I/O address for the first controller is always 1FE hex, and the interrupt is always 14.
If you need more than two IDE drives, you can include a second IDE controller if one is not present on your motherboard. IDE controllers are available for ISA, VESA, and PCI slots. The address for the second controller is usually 170 hex. You will need to determine an available interrupt.
Each IDE drive must be configured as a master or a slave, which is usually done by setting jumpers. The first drive always is configured as a master and is seen by your system as Drive C. If you add a second drive, set its jumpers to the slave setting.
A single ribbon cable with two drive connectors supports both the master and slave drives. Drives can be connected to the cable in any order. However, be sure that line 1 of the ribbon cable attaches to pin 1 of the drive connector. Line 1 usually is identified by a colored stripe along one edge of the cable.

Note: The example shown below represents only one possible jumper configuration, be sure and check your manufacturer's documentation for instructions on setting up master and slave jumpers.
