1 Backup_Notes
 Usage notes on BACKUP:

  (1) Use BACKUP/PHYSICAL for duplicating RX02's and TU58's.

  (2) Copy BACKUP tapes using COPY, but when mounting such tapes
      use /BLOCKSIZE=8464 on the MOUNT command.

  (3) Recreate Standalone Backup's after each system update.

2 Standalone
 The following instances of Standalone Backup appear on the
 Accelerator Control System disks:

  (1) On both Development and Operational System disks (see the
      On_System_Disk subtopic) in [SYSE.SYSEXE].

  (2) On VAXSYSTEMS RL02 in [SYSEXE].

  (3) On KITS RM03 in [SYSEXE].

  (4) On two pairs of RX01's.  One pair is kept inside VAX1 CPU.
      The other (spare) pair is in the file cabinet in my office.

3 On_System_Disk
 To place a copy of Standalone Backup on the system disk, do:

   $ CREATE/DIRECTORY  SYS$SYSDEVICE:[SYSE.SYSEXE]
   $@SYS$UPDATE:STABACKIT  SYS$SYSDEVICE:  [SYSE.SYSEXE]

 To prepare a BCKBOO.CMD boot command file on the console media
 to bootstrap this Standalone Backup, do:

   $ MCR FLX /RS=CS1:DEFBOO.CMD/RT
     Edit the line "DEPOSIT R5 0" to read "DEPOSIT R5 E0000000".
   $ RENAME  DEFBOO.CMD  BCKBOO.CMD
   $ MCR FLX CS1:/RT=BCKBOO.CMD

 To boot Standalone Backup from the (default) system disk, do:

   >>>BOOT BCK

1 Disk_Formatting
 Disks may be reformatted with the EVRAC diagnostics program.
 This note contains descriptions for reformatting RM03 disk packs
 and RX02 floppies.  The floppies may be formatted as either
 SINGLE or DOUBLE density.
2 RM03
 The Diagnostic Supervisor must be run (can be done under VMS).
 The configuration must be setup and then EVRAC may be run under
 the Diagnostic Supervisor.  The series of commands for formatting
 an RM03 disk pack using drive unit "n" on the first Massbus is:

   $ SET DEFAULT SYS$MAINTENANCE:
   $ RUN ESSAA
   DS>ATTACH  RH780  SBI  RH0  8  5
   DS>ATTACH  RM03  RH0  DRAn
   DS>SELECT  DRAn
   DS>RUN EVRAC/SECTION:FORMAT

 and then answer the prompts.  To use the second Massbus, the two
 ATTACH commands are modified (and the SELECT command specifies
 the particular drive to be used):

   DS>ATTACH  RH780  SBI  RH1  9  5
   DS>ATTACH  RM03  RH1  DRBn

2 RX02
 The Diagnostic Supervisor must be run (can be done under VMS).
 The configuration must be setup and then EVRAC may be run under
 the Diagnostic Supervisor.  The series of commands for formatting
 an RX02 floppy disk using drive "n" is:

   $ SET DEFAULT SYS$MAINTENANCE:
   $ RUN ESSAA
   DS>ATTACH  DW780  SBI  DW0  3  4
   DS>ATTACH  RX211  DW0  DYA  777170  264  5
   DS>ATTACH  RX02  DYA  DYAn
   DS>SELECT  DYAn
   DS>RUN EVRAC/SECTION:FORMAT

 and then answer the prompts.  In particular one question will ask
 whether you want SINGLE or DOUBLE density floppies.
