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.

vIf 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.

vIf 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.

vSome non-IBM computers support the cable-select setting, where the position of the device on the cable determines whether a device is primary
