;PROGRAM WHICH BOOTSTRAPS AND DUMPS PDP-11S CONNECTED VIA DL10.
;WHEN RUN, BOOT11 TYPES "FILE: " AND WAITS FOR A FILE SPEC AND
;ONE OR TWO SWITCHES.  /DUMP:M AND /END:N ASK FOR DUMP OF PDP-11
;ACS AND LOC. FROM M-N.
;/LOAD:N AND /START:N SPECIFY BOOTSTRAP FROM FILE AND SET START ADDRESS
;AT N.  IF N IS ODD, OR IF /LOAD, THEN THE 11 WILL HALT BEFORE STARTING.
;/CLEAR:N SPECIFIES TO CLEAR -11 CORE FROM 0 TO N-1.
;IF ALONE, PROGRAM WILL RESTART; IF WITH /L OR /S, WILL THEN LOAD.
;/IMAGE CAUSES LOAD TO READ IMAGE RATHER THAN PACKED FORMAT.
;/PORTNO:P HANDLES PORT NUMBER P (0-3 ARE -11S ON DL-10#0, 4-7 ON #1)

;LOAD INSTRUCTIONS:
;	.LOAD %H BOOT11.MAC, HELPER.REL[10,7]

IFNDEF V.CLR,<V.CLR==100000>	;END OF CLEAR AREA+1
IFNDEF V.DUMP,<V.DUMP==0>	;START OF DUMP
IFNDEF V.END,<V.END==100000>	;END OF DUMP+1
	SUBTTL	REVISION HISTORY

;%2(17)	DELIVERED WITH FIRST DC75 SOFTWARE

;THE FOLLOWING IMPROVEMENTS WERE THEN MADE:
;	HANDLE -11 NXM (BUS TRAP)
;	HANDLE ALL FORMS OF BINARY FORMAT (ABS)
;	HANDLE SFD
;	SUPPRESS 0 LINES FROM DUMP
;	CLEAN UP SOURCE FORMAT
;	RELOCATE THE -11 COMMUNICATIONS AREA TO RELAX THE LOAD
;		TIME REQUIREMENTS
;	PRESERVE THE DL-10 PI-CHANNEL ASSIGNMENT
;	CONVERT MESSAGES TO LOWER CASE
;	CHECK FOR JUNK IN INPUT FORMAT
;	MAKE SIZE OF WINDOW BETWEEN -10 AND -11 BE AUTOMATIC
;	ADD BOOT'S VERSION TO DUMP HEADER LINE
;	ADD /PORTNO:P AND MAKE PORT NUMBER AN OPTION



;DEFICIENCIES:
;	THE AC'S ARE NOT PRESERVED DURING DUMPS. THUS REPEATED DUMPS
;		HAVE JUNK IN THE AC'S.
;	THE AC'S ARE NOT PRESET TO 0 AFTER /LOAD OR /START
;	THERE IS A SLIGHT RACE CONDITION IN THE PRESERVATION OF
;		THE PI-CHANNEL.  THEREFORE THE MONITOR SHOULD
;		ESTABLISH IT AS A CONSTANT AT ONCE TIME AND
;		VERIFY/RESTORE IT OCCASIONALLY (ONCE/SECOND?)


;EDIT 35:  EXECUTES A SET CPU UUO TO LET BOOT11 RUN ON CPU 0 ONLY.
;	   [AREA AFFECTED: STRTUP]

;EDIT 36:  INCREASES THE TIMEOUT OF THE PDP-11 BY A FACTOR OF 10
;	   SINCE NEWER DL10 INTERFACES NEED A LONGER DELAY.
;	   [AREA AFFECTED: STPLP]

;EDIT 37:  LOCKS BOOT11 AT A 1K BOUNDARY TO INSURE PROPER OPERATION
;	   ON A KI WITH THE 8K DL10 OPTION.
;	   [AREA AFFECTED: STRTUP]	   

;EDIT 40:  ADDS TYPE OF FAILURE TO LOCK ERROR MESSAGE
;	   [AREAS AFFECTED: MACRO DEFINITIONS, STRTUP]

;EDIT 41:  DETERMINES PHYSICAL LOCATION THAT BOOT11 IS LOCKED IN
;	   CORE EVEN WHEN LOCKED ABOVE 112K ON A KI.
;	   [AREA AFFECTED: STRTUP]

;EDIT 42:  CAUSES BOOT11 TO REQUIRE A PORT SWITCH IF THERE
;	   IS MORE THAN ONE PDP-11 ON THE DL10'S.
; 	   [AREAS AFFECTED: MACRO DEFINITIONS, SETCOD, STRTUP, SWTWIN, STORAGE]

;EDIT 43:  ALLOWS PRINTING OF CPU SERIAL NUMBERS GREATER
;          THAN 999 IN DUMP ROUTINE HEADING FORMAT.
;          [AREA AFFECTED: DMHDV3]

;EDIT 44:  INCREASES TIMEOUTS OF PDP-11 WHEN STARTING AND CLEARING.
;	   [AREAS AFFECTED: STPLP, WAITIN]

;THE ABOVE IS SO-CALLED PACKED MODE.  IN IMAGE MODE, THEY APPEAR
;ONE BYTE PER WORD IN ASCENDING BYTE ORDER.

;	THE BYTES IN -11 ORDERING (IE, AFTER ABOVE UNTANGLING) ARE:
;		ANY NUMBER OF 0 BYTES (DISCARD)
;		CONSTANT 1
;		CONSTANT 0
;		BCL
;		BCU
;		AL
;		AU
;		BC-6 BYTES OF DATA IN ORDER STARTING WITH THE BYTE FOR A
;		C
;			WHERE BC=BCU*400+BCL	THE BYTE COUNT
;			      A =AU *400+AL	THE FIRST BYTE ADDRESS
;			      C =          	THE CHECKSUM
;	THE ABOVE CAN BE REPEATED INDEFINITELY.
;	THE LAST SUCH GROUP HAS BC=6 AND THE STARTING ADDRESS IS A.

;THE CHECKSUM IS A SIMPLE ADD OF THE BYTES STARTING WITH CONSTANT 1 AND
;INCLUDING THE CHECKSUM--THE RESULT IS 0 IN 8 BITS.
