Parallel Port, Floppy and Hard Drive Connections
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 that does not have twisted wires always connects to drive
B.
•
The 80-wire ATA100/66 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 interface and the other connector(s) to your hard drive(s).
Consult the documentation that came with your disk drive for details on actual
jumper locations and settings for the hard disk drive.
