3.3 The I/O Address Map
The I/O address of OME-PIO/PISO series card is automatically
assigned by the main board ROM BIOS. The I/O address can also be re-
assigned by user. Users are strongly recommended to change the auto-
assigned I/O address. The plug & play BIOS will assign proper I/O
address to each OME-PIO/PISO series card very well. The I/O addresses
of OME-PIO-D56/OME-PIO-D24 are given as follows:
