Option Card Problems
A newly installed option card is not working correctly.
Make sure the option card is installed correctly and is
well-seated in its slot. Run the SETUP program to update your
computer’s configuration after you install the card. Also,
perform setup procedures for any software you are using with
the option card.
See the documentation that came with the option card to set
any necessary DIP switches or jumpers on the card.
The main system board of your computer may also have some
jumpers that must be set for the option card to work properly.
See Chapter 3 for system jumper information.
Your system may need to operate at the slower processor speed
to access the device. Try reducing the processor speed (see
Chapter 2) or inserting a wait state through the SETUP
program (see Chapter 1).
Make sure the option card is not touching any other card
An external device connected to the option card is not
working correctly.
Make sure you are using the proper cable to connect the device
to the card.
