2-7 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.
