The I/O Address Map
The I/O address for PISO-1730U card is automatically assigned by the main board ROM BIOS.
The I/O address can also be re-assigned by the user. It is strongly recommended that users
do not change the I/O address. The Plug&Play BIOS will effectively perform the assignment
of proper I/O addresses to each PISO-1730U card. The I/O address for the PISO-1730U is
given in the table below, all of which are based on the base address of each card.
