This function routes select function calls to the BIOS on Extended Industry Standard Architecture (EISA) hardware that conforms to the EISA specifications.

The Query EISA Configuration Information function supports two subfunctions. Each of these two subfunctions corresponds to an equivalent EISA BIOS INT 15h, AH=D8h function call. These two subfunctions are:
