Installing a DVD-RW as the Second Device on an IDE Cable

C.

When installing a DVD-RW as the second device on an IDE cable, the jumper should be set to Cable Select.

IDE (Integrated Drive Electronics) is an older technology that is used to connect storage devices such as hard drives, CD/DVD drives, and tape drives to a computer's motherboard. Each device connected to an IDE cable needs to have a unique identifier or address so that the computer can recognize it.

The jumper is a small plastic piece on the back of the DVD-RW drive that connects two pins together. By connecting different pins, the jumper controls the device's identifier or address.

There are two common methods for setting the jumper on IDE devices: Master/Slave and Cable Select.

In the Master/Slave method, each device on the IDE cable is assigned a fixed identifier. The device connected to the end of the cable is usually set as the Master, and the device connected in the middle of the cable is set as the Slave.

In the Cable Select method, the device's identifier is determined by its position on the IDE cable. The device connected to the end of the cable is automatically set as the Master, and the device connected in the middle of the cable is automatically set as the Slave.

When installing a DVD-RW as the second device on an IDE cable, it is recommended to set the jumper to Cable Select. This will allow the device to be automatically identified as the Slave, and the existing device on the cable will be identified as the Master.

Option A (ID0) and Option B (ID2) are incorrect because they refer to specific Master/Slave identifiers, which are not applicable in this scenario.

Option D (Master) is incorrect because setting the jumper to Master would make the DVD-RW drive the primary device on the IDE cable, and the existing device would be identified as the Slave. This would cause conflicts and may prevent the computer from recognizing both devices.
