2-9 Floppy, IDE, Parallel Port, SAS and SATA Drive

Connections

Use the following information to connect the ﬂ oppy and hard disk drive cables.

 The ﬂ oppy disk drive cable has seven twisted wires.

 A red mark on a wire typically designates the location of pin 1.

 A single ﬂ oppy disk drive ribbon cable has 34 wires and two connectors to provide

for two ﬂ oppy 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 ATA133 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.
