2-8 Parallel Port, Floppy/Hard Disk Drive and SCSIConnections
Note the following when connecting 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 that does not have twisted wires
always connects to drive B.
• The 80-wire ATA66/100 IDE hard disk drive cable that came with your
system has two connectors to support two drives. This special cable
should be used to take advantage of the speed this new technology
offers. The blue connector connects to the onboard IDE connector inter-
face and the other connector(s) to your hard drive(s). Consult the docu-
mentation that came with your disk drive for details on actual jumper
locations and settings for the hard disk drive.
