The following cables are provided:v Four-wire power cables connect the drives to the power supply. At the end ofthese cables are plastic connectors that attach to different drives; theseconnectors vary in size. Also, certain power cables attach to the system board.v Flat signal cables, also called ribbon cables, connect IDE, SCSI, and diskettedrives to the system board. There are two sizes of ribbon signal cables that comewith your computer.– The wider IDE signal cable has two or three connectors.- If the cable has three connectors, one of these connectors is attached to thedrive, one is a spare, and the third attaches to the primary or secondaryIDE connector on the system board.- If the cable has two connectors, one of these connectors is attached to thehard disk drive, and the other attaches to the primary or secondary IDEconnector on the system board.Note: If you want to add another device, and your computer does notcome with a CD-ROM drive preinstalled, you will need a secondsignal cable with three connectors.
