4 IDE connector. This is used to connect the CD-ROM drive to the IDE cable.
5 DC power connector. This is used to connect the dc power cord to the
CD-ROM drive.
Installing the drive
Follow these steps to install the CD-ROM drive in your computer.
Step 1. Opening the computer
1. Turn off the computer and all attached devices.
2. Unplug the power cords for the computer and all attached devices.
3. Remove the cover from the computer.
Step 2. Unpacking the drive
1. Before opening the antistatic bag that the drive is packed in, touch it to an
unpainted metal surface for at least two seconds. This will drain the static
electricity from the package and your body.
2. Remove the drive from the antistatic bag. If you must put the drive down,
place the antistatic bag on a flat padded surface, such as a magazine, and
place the drive on the antistatic bag.
Step 3. Selecting the IDE port
Newer computers typically have two IDE ports, each of which can support two
devices. Typically, the IDE port to which your hard disk drive is connected is
the primary IDE port. The other IDE port is the secondary port. The IDE port
and the cable position that you select determine which configuration jumper
setting that you use for the drive.
v If you have two IDE ports, connect the CD-ROM drive to the secondary IDE
port on your system board or IDE adapter. If the CD-ROM drive is the only
device on the secondary IDE port, use the primary configuration setting. If
the CD-ROM drive is the second device on the secondary port, use the
secondary configuration setting.
v If you must attach the CD-ROM drive to the primary IDE port (the same
port as a hard disk drive or other fast device), use the secondary setting for
the CD-ROM drive and the primary setting for the faster device. In some
instances, you might need to change the hard disk drive configuration
setting to master-with-secondary-present when attaching a secondary device
on the same cable. For further information on setting configuration jumpers
on other devices, refer to the documentation that came with your computer
or with the device in question.
v Some non-IBM computers support the cable-select setting, where the
position of the device on the cable determines whether a device is primary
