Installing the Drive
Before you can install a drive in one of the external bays, you
must first remove the mounting bracket with the diskette drive
(and possibly a hard disk drive). See page 4-2 for instructions.
Then follow these steps to install a drive in the upper or lower
drive bay:
1. Remove the faceplate from the bay by pushing it out from
the inside of the computer.
Keep the faceplate in a safe place in case you remove a drive
later (or you are installing a hard disk drive).
