WHEN USING A SECONDARY CONTROLLER
* If your PC has an additional IDE controller on the motherboard or on a system slot, each
IDE device connected to the secondary IDE controller must also be set to the Master or
Slave mode. If you are connecting your CD-ROM drive to a secondary IDE card, and it
is the 1st device you are connecting to it, then set the CD-ROM jumper to the Master
position. If it is the 2nd device, set the CD-ROM jumper to the Slave position.
* Depending on the IDE card and whether the CD-ROM drive is a master or slave
unit, the diagram below represents the different ways in which the CD-ROM may
be configured in your PC. The table below the diagram shows the possible Jumper
placements that would correspond to each of the different configurations shown.

do not install an IDE controller card in your system.
