Library /sys$common/syshlp/nclhelp.hlb boot, mop, client, software_id  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    To override any default System Image information for this
    Client in the MOP Client database, whenever System Image
    information is required by the target system for the boot
    operation:

    boot  [node node-id] mop client client-name software id string

    Software Id is an optional argument, but Address and Circuit
    information is required, either from the command line or from
    the MOP Client database.

    Example:

    boot mop client lamchp software id "-1"
