3.3The 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:
