The Base Address and IRQ parameters are
configurable only if the Parallel Port is enabled.

If you install an add-on card that has a parallel port
whose address conflicts with the parallel port on
board, a warning message appears on the screen.

Check the parallel port address on the add-on card
and change the address to one that does not conflict.
