IRQ

This function lets you assign an interrupt for the parallel port. The

options are IRQ

and

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 onboard, 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.
