Term This enables or disables (turns ON or OFF) SCSI termination. Factory setting
is Enabled (ON). See page 18 for an explanation of SCSI termination and to
determine if you need to change this setting.
Test Leave this OFF. It is for factory use only.
Block Leave this OFF unless you are working in a UNIX environment and want to
boot from your CD-ROM drive. If so, set this switch/jumper ON.
Eject In most situations, you will want to leave this switch/jumper OFF.
However, if you are in an environment where you want to prevent others
from borrowing or stealing the disc inserted in your drive (e.g., the drive is
located in a public place where multiple people have unlimited access), you
can activate the Eject Lock feature. To do so, set this switch/jumper ON.
When this switch/jumper is ON, it is impossible to eject a disc inserted in
the drive by pressing the Eject button. A software eject command must be
issued for the disc to eject from the drive. Check your device driver manual
for instructions on how to issue a software eject command.
