If default I/O port addresses conflict with other I/O cards (e.g. sound cards
or I/O cards ) , you must adjust one of the I/O addresses to avoid address
conflict. (You can adjust these I/O addresses from the BIOS)

Note: Some sound cards have a default IRQ setting for IRQ7, which
may conflict with printing functions. If this occurs do not use sound
card functions at the same time you print.
