5 Jumper Settings
This appendix explains the jumper settings on the drive and lists the pin
configurations of each connector on the rear panel.
There is one jumper at the rear of the CD-ROM drive. This jumper determines
how your CD-ROM drive functions. The figure and table below show the four
possible jumper settings and their functions.
Jumper Setting Function
C Use CSEL
M Master
S Slave
None Slave
The drive comes preset with the jumper at the S pin. This means that the drive
is set as a slave. In this case, your hard disk drive would be the master drive.
To change the jumper setting, remove the jumper cap and insert the pin for the
desired function.
