Welcome to the Intel® Embedded Community.
In another of your posts, you mentioned that you are working with Pillar Rock CRB. According to the user docs for Pillar Rock, the Port 80-83 Add-in card should be included in that Development Kit.
Can you please clarify your situation. Do you have Pillar Rock but missing the card?

The best way to answer that would be to check with your supplier where you sourced the original Intel Development Kit, e.g. local distributor. They would be able to tell you if that card is available.
By the way, scanning that user's doc I mentioned, I do notice that all of the other add-in cards associated with the development kit have their own unique product code names- such as Duck Bay 3, Mott Canyon 4, Eaglemont, etc. The Port 80-83 card is the only one that does not have it's own name. This leads me to guess that it may not be available separately, but that is just my guess. Best check with your Intel source.
