System Security Setup

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 adjust the address to one that does not conflict.
