Multi I/O Port Addresses
Default settings for multi I/O port addresses are shown in the table below.

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.
