Option Card Problems
If you install an option card and it is not functioning properly,
check the following:

Is the option card installed correctly? The most common
problem with option cards is a loose connection. Make sure
the option card is well-seated in its slot. Check the
installation procedure described in Chapter 5 and also see
the instructions that come with the option card.
Did you set the necessary DIP switches or jumpers on the
option card? See your option card manual for instructions.
Did you set the necessary jumpers on the main system board?
See Chapter 5 for more information.
Did you run the Setup program to redefine your computer’s
configuration after installing the card? See Chapter 2.
Did you install a hard disk drive that has its controller on an
option card? If so, and if your computer came with a hard
disk drive that you are no longer using, be sure the cable
leading from that drive to the main system board and the
hard disk drive power cable are disconnected.
Did you install a network option card in your computer?
Some network option cards require your computer to
generate an early input/output ready signal to operate
properly. If you are having trouble using your network card,
set jumper JPl on the main system board to position A to
enable the early input/output ready signal. Then try using
the network card again. If it still does not operate correctly,
contact your dealer.
If you used the option card to add an external device to your
computer, did you use the proper cable to connect the
device to the option card connector on the back panel?
