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.
Operation Mode
This item allows you to set the operation mode of the parallel port. Table 3-1 lists
the different operation modes.
