Option Card Problems
If you install an option card and it is not functioning properly,
check the following:
1. Is the option card installed correctly? The most common
problem with option cards is a loose connection. Make sure
the card is well-seated in its slot. Check the installation
procedure described in Chapter 5 and also see the
instructions that come with the card.
2. Did you set the necessary DIP switches or jumpers on the
option card? See your option card manual for instructions.
3. Did you set the necessary jumpers on the main system board?
See Chapter 5 for more information.
4. Did you run the SETUP program to update your
configuration after installing the card? See Chapter 2.
5. 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?
6. Did you perform the correct setup procedures for the
software you are using with the option card? If necessary, see
your software manual for instructions.
7. 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.
