Set the Drive’s Mode Jumper
You specify your drive's Master, Slave, or Cable Select setting before installing it.
You do this by changing the position of a jumper on the mode jumper block at the
rear of the drive.
Your drive ships from our factory with its mode jumper set to operate the PX-504A
as a Master. This will work in most custom system configurations. If your computer
is from a large OEM system manufacturer such as IBM, Hewlett Packard, Gateway
or Compaq, you will need to pay particular attention to whether the computer uses
the Cable Select scheme.
Changing the Mode Jumper on Your Internal PX-504A Drive
The drive arrives from the factory with its mode jumper set to Master. (A function is
ON if the jumper is installed and OFF if the jumper is removed.)

Changing to a Master, Slave, or Cable Select
The Master/Slave/Cable Select setting for the drive is determined by the mode
jumper. The jumper is placed over one of the sets of mode pins. To change the drive
from Master to Slave or to Cable Select, you must move the jumper.
For example, to change the drive to be a Slave, move the jumper to the right set of
mode pins, leaving the other pins uncovered. To change the drive for Cable Select,
move the jumper to the left set of mode pins.
Note that if any device is jumpered as Cable Select, then both devices connected to
that cable must be jumpered as Cable Select. In addition, the cable you use must be a
special Cable Select cable.
