Dell OptiPlex E1 Reference And Installation Manual page 113

The 5.25-inch drive bay can accommodate any of the following types of drives:
A diskette drive or tape drive that uses the diskette/tape drive interface on the
system board
A CD-ROM or tape drive that uses the secondary EIDE interface on the system
board
A CD-ROM or tape drive that uses its own controller card
To install a drive in a 5.25-inch drive bay, follow these steps:
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.
Press outward on the two tabs on the left side of the drive bay to disengage the
bracket from the chassis (see Figure 7-6). Then rotate the bracket upward, and
remove it from the chassis.
