Sonnet Technologies Tempo Ultra ATA66 Host Adapter - Manual (Page 19)

Jumper Pin Settings
Adjusting the jumper pins of a drive’s jumper block
designates the primary (master) or secondary (slave)
settings of the drive. Figures 4-7 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 on 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
jumper pins of 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 7), 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 jumper pins of
the drive’s jumper block.

Support Note: Make sure to properly
configure the jumper pins of the hard
drive(s) for your system set-up, or your computer
may not boot.
