5-12 Floppy, IDE, SCSI and SATA Drive Connections
Use the following information to connect the IDE hard disk drive cables.
• A red mark on a wire typically designates the location of pin 1.
• 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.
