Components: Slave hard drives

How can you designate a hard drive as a slave? (Select TWO.)
1. >>Connect the hard drive to the motherboard using the Slave connector portion of a Cable Select cable.
2. Designate it as Slave in the BIOS Setup.
3. Set the Master jumper to Off.
4. >>Set the dip switch on the hard drive to Slave instead of Master.

Explanation : When running a dual-drive configuration, you must designate one hard drive as master, and the other as slave. There are two ways to do this: set the Master jumper to Off, or connect the hard drive using the Slave connector portion of a Cable Select cable. Older drives use jumpers to set a hard drive as master or slave. The jumper will be On if the hard drive is the master, or Off if the hard drive is a slave.

Cable Select is a newer way to designate a hard drive as master or slave. A special IDE cable is used to connect the hard drives to the motherboard. There are two connectors on the cable: one for Master, and another for Slave. The Slave connection will not transmit data through pin 28, so only the master hard drive receives the signals sent across pin 28.

Dip switches are NOT used to designate hard drives as master or slave.

The BIOS Setup will determine which one is the master by how the jumpers or Cable Select is set. You cannot designate a hard drive as master or slave through the BIOS Setup.
