National Instruments Corporation

Board Configuration

The PCI-DIO-96 is completely software configurable. The PCI-DIO-96

is fully compliant with the PCI Local Bus Specification, Revision 2.0.

Therefore, all board resources are automatically allocated by the PCI

system, including the base address and interrupt level. The base address

for the PCI-DIO-96 is mapped into PCI memory space. You do not need

to perform any configuration steps after the system powers up.
