1.7 License Registration
  DECpresent includes support for the ULTRIX License
  Management Facility (LMF). A License Product Authorization
  Key (License PAK) must be registered in the License
  Database (LDB) in order to use DECpresent on a newly-
  licensed node.

  The License PAK may be shipped along with the kit if you
  ordered the license and media together; otherwise, it is
  shipped separately to a location based on your license order.

  To register a license under ULTRIX:
  1. Log in as superuser.
  2. At the superuser prompt, edit an empty PAK template
        with the lmf register command and include all the
        information on your License PAK as follows:
        # lmf register
  3. Load the license using the following command:
        # lmf load USERS PRODUCT-NAME

        For most installations, USERS can be set to 0. See the lmf(8)
        reference page for more information. PRODUCT_NAME is the
        LMF product name on the License PAK.
  4. Enable the license using the following command:
        # lmf enable PRODUCT-NAME

  After you register your license, use the following lmf reset
  command to copy the license details from the License
  Database (LDB) to the kernel cache:
  # lmf reset

  For complete information on using the ULTRIX License
  Management Facility, see the ULTRIX Version 4.0 Guide to
  Software Licensing or the lmf(8) reference page.
