  • Page 7: Eeupdate Utility

    EEUPDATE Utility Intel has created an EEUPDATE utility that can be used to update the GbE region images during in-circuit programming. The tool uses two basic data files outlined in the following section (static data file and IA address file). The EEUPDATE utility is flexible and can be used to update the entire GbE region image or only the IA address of the LAN controller.
