Connecting Parallel, Floppy and Hard Disk Drives

Use the following information to connect the floppy and hard disk drive cables.

• The floppy disk drive cable has seven twisted wires.

• A red mark on a wire typically designates the location of pin 1.

• A single floppy disk drive ribbon cable has 34 wires and two connectors to

provide for two floppy disk drives. The connector with twisted wires always

connects to drive A, and the connector without twisted wires always

connects to drive B.

• An IDE hard disk drive requires a data ribbon cable with 40 wires.

• A single IDE hard disk drive cable has two connectors to provide for two

drives. To select an IDE disk drive as C, you would normally set the

drive select jumper on the drive to DS1 (or Master). To select an IDE

disk drive as D, you would normally set the drive select jumper on the

drive to DS2 (or Slave). Consult the documentation that came with your

disk drive for details on actual jumper locations and settings.
