01/07/87 load_from_tape, lft Syntax as a command: lft tape_name {-control_args} Function: loads MPC firmware, ITRs, MDRs, and T&D test pages from the Integrated, Firmware And Diagnostic (IFAD) tape into a tandd_deck_file. In addition, MPC firmware modules are loaded into individual segments in a form acceptable to the generate_mst command, in order that they may be written onto the Multics Boot Tape. Also, a DN6670 Binary Deck Tape may also be loaded into the tandd_deck_file. Arguments: tape_name specifies the name of the tape to be used. See "Notes on tape name" below. Control arguments: -brief, -bf suppresses messages from deckfile_manager specifying the deckfile.list and tandd_deck_file that will be used for this request. -copy {-copy_args}, -cp {-copy_args} produces a tailored copy of an IFAD tape for use with offline T&D. Only those modules applicable to Multics are written to the copy tape. The -copy argument is mutually exclusive with the -deckfile, -firmware. For a list of -copy_args, see "List of copy args" below. -density , -den specifies the initial density setting for tape attachment. Although the density of the input tape is automatically determined, some tape subsystems may not have tape drives capable of handling the default density of 1600 bpi. The allowable values for are 6250, 1600, 800, 556, or 200. See "Notes on tape name" below. -firmware, -fw specifies that only firmware modules are to be loaded into individual segments; no deckfile or listing file is produced. This argument is mutually exclusive with the -deckfile, -list, and -copy arguments. -patches allows patches with zero checksums to be accepted. The checksum is adjusted before the record is written to the deckfile. -track , -tk where is 7 or 9 (for 7- or 9-track tapes). If the -track argument is not specified, 9-track is assumed. Notes The default action of this command, if no control arguments are specified, is to load all modules on the tape that are applicable to Multics into the deckfile and all firmware modules into individual segments. Firmware segments are created (in memory image format) using a four component entry name: fw... where name is the name of the device, ident is taken from the MPC-assembler IDENT pseudo-op card, and fw_rev is the firmware revision. Each module that is read from the tape and written to the deckfile is copied as-is in GCOS object deck format. Each object deck occupies one record of the keyed sequential deckfile. The record search key is formed from information obtained from the $!OBJECT card. Catalog records are built for all tape files while the respective tape files are being read. These catalog records are merely a list of all of the search keys associated with each individual tape file. Each catalog record is written to the deckfile immediately following each tape file, and have record search keys in the form: cata.itr.. - for an ITR catalog or cata.mdr.. - for an MDR catalog where: is the name taken from the ident pseudo-op card image is the name of the generic peripheral group and can be either tape, disk, print, or card is the revision of the mpc firmware in this file. For the urcmpc itr/firmware file, it is the revision of the common mpc firmware. Notes on tape name: The tape name may be of any format, but it is recommended that the name used reflect the tape being read, ie an ifad tape would be ifad.b3 or for a FNP 6670 tape name would be 6670-a3. This name is added to the tandd_deck_file and deckfile.list files and can be used as a record of revision of the source used to create the deckfile. The convention of "tape_name,density" where density is the density of the tape, is also supported. List of copy args:: The copy_args pertain only to the and may be chosen from the following: -density , -den sets the density of the copy tape to . The allowable values for are 6250, 1600, 800, 556, and 200. If the -density argument is not specified, the copy tape is set to the density of the input tape. -track , -tk where n is 7 or 9 (for 7- or 9-track tapes). If the -track argument is not specified, 9-track is assumed. ----------------------------------------------------------- Historical Background This edition of the Multics software materials and documentation is provided and donated to Massachusetts Institute of Technology by Group BULL including BULL HN Information Systems Inc. as a contribution to computer science knowledge. This donation is made also to give evidence of the common contributions of Massachusetts Institute of Technology, Bell Laboratories, General Electric, Honeywell Information Systems Inc., Honeywell BULL Inc., Groupe BULL and BULL HN Information Systems Inc. to the development of this operating system. Multics development was initiated by Massachusetts Institute of Technology Project MAC (1963-1970), renamed the MIT Laboratory for Computer Science and Artificial Intelligence in the mid 1970s, under the leadership of Professor Fernando Jose Corbato. Users consider that Multics provided the best software architecture for managing computer hardware properly and for executing programs. Many subsequent operating systems incorporated Multics principles. Multics was distributed in 1975 to 2000 by Group Bull in Europe , and in the U.S. by Bull HN Information Systems Inc., as successor in interest by change in name only to Honeywell Bull Inc. and Honeywell Information Systems Inc. . ----------------------------------------------------------- Permission to use, copy, modify, and distribute these programs and their documentation for any purpose and without fee is hereby granted,provided that the below copyright notice and historical background appear in all copies and that both the copyright notice and historical background and this permission notice appear in supporting documentation, and that the names of MIT, HIS, BULL or BULL HN not be used in advertising or publicity pertaining to distribution of the programs without specific prior written permission.
