                Any VS 5000/6000 with:
                     Floppy Diskette Drive (5-1/4" 1.2 Mb)
                     One (1) Workstation to act as Workstation Zero (System Console)


          2.2   SOFTWARE REQUIREMENTS

                For the VS Resource Control Unit:
                     PROM Part Numbers: 379-5025R1, 379-5026R1
                     PROM Revision: 1.00.01  or later
                For the VS SIO IOC (If used for Workstation 0 control):
                     PROM Part Numbers: 379-2127, 379-2128
                     PROM Revision: 1.00.00 (5860) or later



          CHAPTER 3
          PROBLEMS CORRECTED IN RELEASE 2.12.00


                Release 2.12.00 was packaged with a corrupt @RCUDAT file.  That problem
                has been corrected in this release.



          CHAPTER 4
          RESTRICTIONS AND SPECIAL CONSIDERATIONS

                The Small VS RCU-Class Diagnostic package offers an auto-start feature.
                Within several seconds of displaying the IPL Drive Select screen, the
                system will automatically attempt to IPL.  To override this feature,
                simply depress the function key PF16.  Auto-start IPL will fail due to
                the lack of appropriate microcodes on the diskette.  However IPL from
                another volume may be selected.

                To use this program with workstation zero connected to a SIO IOC the
                following files, which are not part of this package, are required.

                @MC4205    Workstation microcode
                @MC50V67   SIO IOC microcode
                @SB0861    IOC boot loader






          CHAPTER 5
          SPECIAL CONDITIONS

                None are known at this time.

          CHAPTER 8
          INSTALLATION INSTRUCTIONS

                No installation is required, bootstrap and diagnostic execution can be
                accomplished from the diskette.  These files may be copied/backed up to
                the VS IPL volume.  If this is done, a DISKINIT RELABEL of the IPL
                volume must be performed prior to the next IPL to update the pointer to
                the file @MCBOOT@.  The same volume name can be used on the relabel.
