Parallel Port Connector
The parallel port is designated as
J15. See Table 2-34 for pin defini-
tions.
2-8 Parallel Port, AGP, Floppy/Hard Disk and SCSI
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 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 advanced technology offers.
The blue connector connects to the onboard IDE connector interface and
the other connector(s) to your hard drive(s). The middle connector is for
the slave device and the remaining connector is for the master device.
Consult the documentation that came with your disk drive for details on
actual jumper locations and settings for the hard disk drive.
