NOTE: If you are installing a non-EIDE tape drive, check the documentation for the drive to determine the jumper or switch
settings used to designate the drive as drive address DS4 (not DS2 or DS3 as may be indicated in the drive documentation).
Unless the drive is already set to drive 4, reconfigure its jumper or switch setting (see "Jumpers.")
If you are installing an EIDE CD-ROM or EIDE tape drive, configure the drive for the Cable Select setting.

Turn the drive upside down and locate the four screw holes around its perimeter. Fit the bracket over the drive, and then tilt the drive (front
upward) so that the bracket drops down into place. To ensure proper installation, all screw holes should be aligned and the tabs on the front
of the bracket should be flush with the front of the drive (see Figure 7).

To further ensure proper positioning of the drive in the chassis, insert and tighten all four screws in the order in which the holes are numbered
(the holes are marked "1" through "4").
