I am afraid I do not have much input for you right at this forum.
The DH67CF is an ITX form factor (mini-cube PC) type board, thatbehaves pretty much like a standard PC with all the common interfaces.

The best place to look for detailed information in this platform is the Embedded Design Centerhttp://edc.intel.com .

They also have an embedded forum athttp://embedded.communities.intel.com/threads/ which is probably a good place to resubmit a question and get a more detailed answer for your question.

Below are some specific links:
