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

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

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

    Device 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 device "sva"
