The best way to access the PCI-DIO 96 card and its functionalities is to use the NI-DAQ driver API. A help reference is also installed indicating what the functions are and how to access the card.
I know what you are referring to though. Our non-ISA and our newer products are all strictly memory mapped I/O products (on the memory bus). There is no need for an Input/Output Range to access the hardware. Similarly, most new PCI devices won't have an I/O Range. They are essentially not on the I/O bus (I/O memory space). Only devices such as display adapters, serial ports, parallel ports etc. and older devices will still have I/O ranges. Let me know if there is anything else I can help you with. Have a good day.
