- 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.

– The narrower signal cable has two connectors for attaching the diskette drive

The following are some important points to remember when connecting power and
signal cables to internal drives:
v 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.
v When you install a drive, ensure that the drive connector at the end of the signal
cable is always connected to a drive; also, ensure that the drive connector at the
other end is connected to the system board. This reduces electronic noise from
the computer.
v If two IDE devices are used on a single cable, one must be designated as the
primary or master device and the other as the secondary or slave device;
otherwise, some of the IDE devices might not be recognized by the system. The
primary or secondary designation is determined by switch or jumper settings on
each IDE device.
v 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 the master device.
v If you have only one IDE device on a cable, it must be set as master.

come with a CD-ROM preinstalled, you will need a second signal
cable with three connectors. You will need an 80-conductor ATA 100
signal cable if you are replacing the existing signal cable or adding a
second hard disk. ATA 100 signal cables are color-coded. The blue
connector attaches to the system board, the black connector attaches
to the master device, and the gray middle connector attaches to the
secondary (or slave) device.
If your computer comes with a CD-ROM drive, it will have an ATA
100 signal cable. However, if you are installing a hard disk drive,
you must change the switch or jumper setting on the CD-ROM drive
to secondary and change the connector used for the CD-ROM drive
to the gray middle connector.
