Installing an Expansion Adapter

You can install two full-length adapters in your computer.  The audio
adapter is installed in the bottom expansion slot.

>  Note:  Certain video adapters require you to disable the
   SVGA circuitry on the main logic board by changing the
   setting of On-Board Video jumpers.  Refer to "Changing
   Jumper Settings" for information.

Before you begin, carefully read the following steps and the
documentation provided with the expansion adapter.  To install an
expansion adapter:

1.  Turn off the computer, and disconnect all cables.

2.  Discharge any accumulated static electricity from
    your body by touching a grounded metal object.  Then,
    open the computer.  Refer to "Opening the Computer."

3.  Remove the screw and expansion slot cover.  Save the
    slot cover in case you later remove the expansion
    adapter.

>  Caution:  The bottom expansion slot contains the audio
   adapter.  The bottom slot supports a half-length adapter
   (or any adapter up to 8 inches long).  Installing a
   longer adapter in the bottom slot will restrict your
   access to main logic board components.

4.  Press the expansion adapter into the expansion slot
    connector on the adapter connector.  When installing a
    full-length adapter, be sure to position the adapter
    correctly in the front guide slot.

5.  Secure the expansion adapter bracket, using the screw
    you removed earlier.

6.  Connect expansion adapter cables (if any) as specified
    by the instructions provided with the adapter.

7.  Check that the internal cables are securely connected
    and do not cause mechanical interference.  Then, close
    the computer.  Refer to "Closing the Computer."

8.  Update the worksheet at the end of this manual.

9.  Run the setup utility to update the system
    configuration.  Refer to the "Utilities" section.
