5. If you are installing a new CD-ROM drive for the first time, install two guide screws on each
side of the drive.
6. Position the guide screws on the drive into the J-slots in the drive bay, and slide the drive
towards the front of the computer. Ensure that the spring-loaded drive release latch properly
secures the drive.
CAUTION: Use only 3/16-inch or 5-mm long screws as guide screws. Longer screws can damage the
internal components of the drive.
7. Install the flat ribbon cable onto the back of the drive.
The flat ribbon cable is a multifunction cable that transmits power, audio, and data
between the CD-ROM drive and the system board.
8. If this is a new installation, raise the drive cage to the upright position and connect the flat
ribbon cable to the system board.
