! COMMAND AND DOCUMENTATION FILE TO UPDATE THE DISTRIBUTION RT11-V4 HANDLER
!   DYV4DS.DOC  30-DEC-80	880 VERSION

! THIS FILE BOTH DOCUMENTS THE PROCEDURE AND CONTAINS THE COMMANDS
! REQUIRED TO MODIFY THE DEC RT11-V4 RX02 HANDLER TO SUPPORT DOUBLE
! SIDED OPERATION.
!
! SETUP FOR DUAL FLOPPY SYSTEM
! ----- --- ---- ------ ------
!
! FIRST MAKE A COPY OF THE RX02 BOOTABLE DISTRIBUTION DISKETTE.
! THEN BOOT THIS DISK IN DY0: (LEFT HAND DRIVE)
! THEN COPY THE FILES (DYV4DS.DOC AND DYV4DS.DIF) FROM THE DSD DIAGNOSTIC DISK
! TO THE BOOTED RT-11 V4 DISKETTE IN DY0:.
!
! NOTE: THERE SHOULD BE AT LEAST 40. CONTIGUOUS FREE BLOCKS ON THIS DISK.
!       AND IT MUST CONTAIN DY.MAC, MACRO.SAV, LINK.SAV, SYSMAC.SML AND DUP.SAV
!
! SETUP FOR SINGLE FLOPPY SYSTEM (DSD880)
! ----- --- ------ ------ ------ --------
!
! 1)	COPY THE BOOTABLE RT-11 DISTRIBUTION DISKETTE ONTO THE WINCHESTER DRIVE
!	    INSERT THE BOOTABLE RT-11 DISTRIBUTION DISK INTO DY0: AND BOOT IT.
!		INIT DL0:
!		COPY /SYS DY0:*.* DL0:
!		COPY /BOOT DL0:RT11SJ DL0:
!		BOOT DL0:
! 2)	COPY DY.MAC FROM THE DRIVER SOURCE DEC DISTRIBUTION DISKETTE TO DL0:
!		COPY DY0:DY.MAC DL0:
!
! 3)	COPY THE DYV4 FILES FROM THE DSD DIAGNOSTIC DISKETTE TO DL0:
!		COPY DY0:DYV4*.* DL0:
! COMMON UPDATE PROCEDURE FOR ALL HARDWARE CONFIGURATIONS.
! ------ ------ --------- --- --- -------- ---------------

!
!
! THE USER SHOULD THEN TYPE THE QUOTED COMMAND TO THE MONITOR PROMPT.
! ."@DYV4DS.DOC<CR>"
!
! UPDATE THE DY.MAC SOURCE FILE USING SLP (SOURCE LANGUAGE PATCHER)
R SLP
DYV4DS.MAC,=DY.MAC,DYV4DS.DIF

!THIS PRODUCES A REVISED HANDLER SOURCE THAT WILL NOW BE ASSEMBLED
!
R MACRO
DYV4DS,=DYV4DS

!
! SAVE THE DEC STANDARD HANDLER BY RENAMING IT.
!
RENAME /SYS/NOPROTECT DY.SYS DY.SYS
RENAME /SYS DY.SYS DY.DEC
!
! GENERATE THE NEW DY.SYS HANDLER FILE
!
R LINK
DY.SYS=DYV4DS

!
! THE NEW HANDLER SHOULD BE BOUND TO A MONITOR ON THE FLOPPY USING COPY/BOOT
!	INSERT A BOOTABLE RT-11 V4 FLOPPY INTO DY0: FOR HANDLER UPDATE

COPY /SYS DY.SYS DY0:DY.SYS
COPY/BOOT DY:RT11SJ.SYS DY:
! OR FOR THE FOREGROUND/BACKGROUND MONITOR
! COPY/BOOT DY0:RT11FB.SYS DY:
