Check the documentation that accompanied the drive to verify that the drive is
configured for your computer system. Change any settings necessary for your
configuration.
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 documen-
tation). Unless the drive is already set to drive 4, reconfigure its jumper or switch
setting (see “Jumpers” and “Switches” in Chapter 5).
If you are installing an EIDE CD-ROM or EIDE tape drive, configure the drive for
the Cable Select setting.

Squeeze the metal tabs that extend from each side of the drive bracket toward
each other, and pull the bracket out of the bay (see Figure 7-6).
