LG GH22NP21 - Manual (Page 8)

NOTE : Only one jumper should be installed on the jumper connector.
If more than one jumper is installed, the drive may malfunction or be damaged.
Master/Slave setting is determined by jumper installation on the Jumper Connector.
The following table shows the possible jumper settings.
If you use CSEL setting, the MASTER/SLAVE setting will be made automatically,
depending on the hardware configuration. For more details refer to the manual of
your computer.
PC Connection
The Super Multi DVD Rewriter connects to the motherboard of the host computer
using an IDE interface cable. You may connect the Super Multi DVD Rewriter as a
Slave or Master device, depending on your computer.
To Install as a Master Drive
To install the drive as a Master, the jumper can be left as supplied from the factory.
NOTE : A hard disk is normally installed as the Primary Master on the EIDE (ATAPI)
interface. Other EIDE peripheral devices such as hard drives and Super Multi DVD
Rewriters are then set differently.
