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

    Device is an optional argument which can be used if the target
    system requires device information for the boot operation.
    Address information is required for the boot mop circuit command;
    it must be obtainable either from the command line or from the
    MOP Client database.

    boot  [node node-id] mop circuit circuit-name -
          address lan-address, device device-string

    Or, to override any default Device Types information for this
    Client in the MOP Client database:

    boot  [node node-id] mop circuit circuit-name -
          client client-name, device device-string

    Examples:

    boot mop circuit fddi-1 address 08-00-2b-00-33-44, device "sva"

    boot mop circuit csmacd-1 client lamchp, device "sva"
