5. Troubleshooting
If you are having trouble with your board or program, answer the
following questions to see if you can find the problem.
QUESTIONS:
STEPS TO TAKE
Is the pilot light on?
The system must be turned on and the power supply must be
working. Check the main power switch and the power supply.
Did the system boot up?
If the board has been installed and the system did not boot, check
the following:
- Make sure the board has been inserted firmly. Pull it out and try
to reboot. If your system reboots, then re-insert the board and
try to boot again.
- Check that cables attached to your other boards fit tightly.
Does your program work?
If the system booted and your program does not work, check the
following:
- DIP switches have been set correctly for the desired base address.
- Selected base address doesn't conflict with another peripheral
device or card installed in the computer.
- Selected interrupt levels don't conflict with interrupts required by
other devices or cards.
- Try one of the sample programs provided on the disk and see if it
works.
