1.44MB Floppy Drive  (250-4053)     Installation        Faxback Doc. # 5365

To prepare the computer:

Because static electricity can destroy integrated circuits, be sure to
discharge any accumulated electricity by touching a grounded metal object
before you touch the drive or any of the computer's PC boards.

1.  Be sure that the system's power and power to all the system's 
    peripheral devices (monitor, printer, modem, and so on) is off.

2.  Unplug the system's power cord from the wall.

3.  Disconnect the system's peripheral devices.

4.  Remove the system's cover.


To prepare the drive:

Do the following before you install the diskette drive.

1.  Snap the eject button cap onto the eject button tab.

2.  Bend the yellow indicator down until it touches the PC board.  (This
    keeps it from bending in the wrong direction during installation.)

3.  Set the drive designation switch to A, B, C, or D.  This will be the 
    new diskette drive letter designation that you see at your system 
    prompt.  (Do not choose A if your primary drive is already A, or C if 
    your hard drive is already C, and so on.)

Mounting and Connections

Do the following to mount the diskette drive into your computer.

1.  Remove the drive mounting bracket from the computer's drive platform by
    removing the two screws that hold the front of the bracket in place.
    Slide the bracket backward to remove it.

2.  Insert the diskette drive into the bracket.  (Be sure that the front of
    the drive is at the front of the bracket, on the same side as the screw
    tabs.)

3.  Align the drive's mounting holes with the two holes marked F on the
    mounting bracket.  Insert a screw in each hole.

4.  Insert a screw into the opposite side of the mounting bracket.  Choose
    the hole that corresponds with the rear hole marked F.

5.  Locate the drive ribbon cable that connects the main logic board and 
    the factory-installed disk drive.  Connect this ribbon cable's second
    connector to the 34-pin connector on the back of the new drive.  (The
    connector is keyed so that it connects to your drive only one way.)

6.  Slide the bracket assembly back onto the drive platform, making sure it
    locks in place.

7.  Fasten the bracket assembly by replacing the two mounting screws.

Completing the Installation

After you check all the connections, be sure all screws are tightened and
then:

1.  Replace the cover.

2.  Reconnect the peripheral cables and the power cord.

Note:  Be sure to run SETUP to tell the system about the new drive.
See your computer's installation and operation manual for instructions.
