VMS Help TCPIP Services, BOOTP  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The Bootstrap Protocol (BOOTP) server answers network bootstrap
    requests from diskless workstations and other network devices
    such as routers, terminal servers, and network switching
    equipment. When it receives such a request, the BOOTP server
    looks up the workstation's address in the BOOTP database file.

    The Trivial File Transfer Protocol (TFTP) handles the file
    transfer from a BOOTP server to a diskless client or other remote
    system. The client initiates the file transfer.

    Configuring and managing BOOTP on your OpenVMS host involves the
    following tasks:

    o  Planning your BOOTP configuration

    o  Configuring the BOOTP and TFTP components using TCPIP$CONFIG

    o  Modifying the BOOTP configuration using logical names and
       management commands

    o  Creating a BOOTP database

    o  Monitoring the BOOTP and TFTP processes
