5. If you are installing any type of drive other than a serial ATA hard disk drive,
make sure the drive that you are installing is set correctly as either a master
or a slave device.

or a slave device.
v If it is the first optical drive, set it as a master device.

v If it is an additional parallel ATA hard disk drive, set it as a slave device.
Refer to the documentation that comes with your drive for master/slave
jumper information.
