Hi wpao,
If you have already installed the NI-HSDIO driver, you can find example programs by opening the LabVIEW example finder (Help --> Find Examples) and browsing to Hardware Input and Output --> Modular Instruments --> NI-HSDIO.
If you are programming in C or CVI, the examples can be found in C:\Program Files\IVI\Drivers\niHSDIO\Examples
If you do not have an NI-HSDIO CD, you may download the driver by going to ni.com/download and following these links:
Drivers and Updates --> Current Software Versions --> Digital I/O --> NI-HSDIO Version 1.2.1 for Windows.
