Figure 2-5. Removing the Riser-Board Bracket
To replace the riser-board bracket, perform the following steps:
1. Hold the back of the diskette drive with one hand to prevent it from moving as
you perform this process.
2. Slip one finger into the oval opening on top of the riser-board bracket (see
Figure 2-5). Then position the riser-board bracket on top of the diskette drive so
that the riser-board securing tabs fit over both sides of the riser board and its
diskette-drive slots align with the diskette-drive tabs (see Figure 2-5).
CAUTION: When handling the riser board bracket, always hold it by plac-
ing a finger through the oval opening in the bracket (see Figure 2-5). Do
not grasp the bracket by its edges, which may be sharp.
3. Gently push the riser-board bracket toward the front of the computer until its
three back tabs fit into the three slots on the back of the chassis.
4. Replace the riser-board screw (see Figure 2-5).
5. Replace the computer cover according to the instructions in Removing and
Replacing the Computer Cover found earlier in this chapter.
