Checking Device ID Jumper

Check the jumper settings of the Built-in DVD-RAM drive before installing the Built-in DVD-
RAM drive into a 5.25-inch device bay of the computer.
Any IDE device including the Built-in DVD-RAM drive requires a specific ID to be set.
Devices connected on the same IDE bus can operate properly only when each of the
devices has a unique ID different from others.
There are three IDs, or "MASTER," "SLAVE," and "CABLE SELECT." Set the ID of the
Built-in DVD-RAM drive to "SLAVE" because it is connected to the same bus as that of the
factory installed CD-ROM/RW drive (MASTER).
The ID can be set by using jumper pins 1 to 3 on the rear of the Built-in DVD-RAM drive.
(The Built-in DVD-RAM drive is defined as "SLAVE" at the shipment from the factory.)
MASTER (pin 1)
SLAVE (pin 2)
CABLE SELECT (pin 3)
Insert the jumper pin into the pin corresponding to the
selected ID.
