These switches cell the computer how to access the built-in
parallel and serial ports. You do not need co change the factory
settings unless you install an option card with an additional
parallel or serial port. If you do install such a card, read the
following information carefully.
Stitches 1 and 2 (paralle port)—tell the computer how co access
the built-in parallel port.
The built-in parallel port functions as either the primacy or
secondary parallel port. If you install an option card with its
own parallel port, you must set these two DIP switches so there
is no conflict between the built-in port and the additional port.
Here are some examples:
If you install an option card chat has only a parallel port,
you must designate it as the secondary port and leave the
built-in port as the primary port
If you install an option card chat has both a video port and
a parallel port, you must designate this port as primary and
make the built-in parallel port secondary.
