Jumper Settings
Adjusting the jumpers on a drive's jumper block
designates the master or slave settings of the drive.
Figures 10 through 13 illustrate four of the more
common hard drive settings. Your drive may differ
from those pictured.
• Master Drive – The master drive (or in the case
of one drive) must always be installed at the end
of the Ultra ATA66 cable for proper termination.
Most drives are factory preset as a master drive.
Normally you do not need to reconfigure the
jumpers on a master drive since it is already
preconfigured; however, if you are installing only
one drive, and its jumpers allow you to set it with
either a master or single setting (similar to the
setting illustrated for the Western Digital hard drive
in Figure 13), configure it as a single drive.
• Slave Drive – If a secondary drive is installed
onto the intermediate connector of an Ultra ATA66
cable, it is considered a slave drive and must be
properly configured by adjusting the jumpers on the
drive's jumper block.
Support Note:
configure the jumpers of the hard drive(s)
for your system set-up, or your computer may
not boot.
