Power and signal cables for internal drives: Your computer uses cables to
connect IDE devices to the power supply and to the system board. The following
cables are provided:

devices and the computer.
Four-wire power cables connect the drives to the power supply. At the end of
these cables are plastic connectors that attach to different drives; these
connectors vary in size. Also, certain power cables attach to the system board.
Flat signal cables, also called ribbon cables, connect IDE and diskette drives to
the system board. There are two sizes of ribbon cables that come with 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
the drive, one is a spare, and the third attaches to the primary or
secondary IDE connector on the system board.
– If the cable has two connectors, one of these connectors is attached to
the hard disk drive, and the other attaches to the primary or secondary
IDE connector on the system board.
Note: The CD-ROM drive will have an ATA 66 signal cable. ATA 66 signal
cables are color-coded. The blue connector attaches to the system
board. The black connector attaches to the primary device. The gray
middle connector attaches to the secondary device. If you are
installing a hard disk drive, you must change the switch setting on the
CD-ROM drive to secondary and change the connector used for the
CD-ROM drive to the gray middle connector.
— The narrower signal cable has two connectors, one to attach to the diskette
drive, and the other to attach to the connector (FDD1) on the system board.
The drives that are preinstalled in your computer come with power and signal
cables attached. If you replace any drives, it is important to remember which
cable is attached to which drive.
When you install a drive, ensure that the drive connector at the end of the signal
cable is always connected to a drive, and ensure that the drive connector at the
other end is connected to the system board. This reduces electronic noise from
the computer.
If two IDE devices are used on a single cable, one must be designated as the
primary device and the other as the secondary device; otherwise, the computer
might not detect some of the IDE devices. The primary and secondary
designation is determined by switch or jumper settings on each IDE device.
If two IDE devices are on a single cable, and only one is a hard disk drive, the
hard disk drive must be set as a primary device.
If you have only one IDE device on a cable, it must be set as a primary device.
