TITLE BOOT11 TO BOOTSTRAP/DUMP PDP-11 CONNECTED VIA DL10 %4A(44)

;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.
