To deactivate the parallel port, select the 
Disabled
 option.  If you
install an add-on card that has a parallel port whose address conflicts
with the parallel port onboard, the system automatically disables the
onboard functions.
Check the parallel port address on the add-on card and change the
address to one that does not conflict.
