*P*      NAME:    BOOTSUBR
*P*      PURPOSE: THIS MODULE CONTROLS THE CP-V BOOT-TIME
*P*               PROCEDURES (I.E., FOR TAPE BOOT & FOR
*P*               DISC BOOT).
*P*      DESCRIPTION:  THE BOOTSUBR MODULE IS A PART OF THE
*P*               CP-V MONITOR ROOT WHEN BOOTED. BOOTSUBRS ENTRY
*P*               IS MONINIT. BOOTSUBR CAN BE ENTERED IN ONE OF
*P*               SEVERAL WAYS: COLD TAPE BOOT, BOOT TAPE UNDER
*P*               FILES, DISC BOOT, RECOVERY, OR OPERATOR RECOVERY.
*P*               BOOTSUBR DETERMINES TARGET MACHINE TYPE, OC
*P*               ADDRESS, CORE SIZE, BOOT TYPE CODES (IF TAPE BOOT),
*P*               REAL-TIME INFO (IF REAL-TIME SYSTEM), DATE, TIME,
*P*               & THEN ENTER THE TAPE BOOT PORTION OF BOOTSUBR
*P*               IF TAPE BOOT. IF NOT TAPE BOOT, THEN XDELTA IS
*P*               OBTAINED ALONG WITH THE MONITORS EXTENSION & THE
*P*               CORE VALUES ARE DETERMINED. XDELTA IS NOT
*P*               RETAINED UNLESS SO DESIRED. IF THE SYSTEM IS FOR
*P*               NON-REAL-TIME, BOOTSUBR EXITS. HOWEVER, IF IT IS
*P*               REAL-TIME, THEN REAL-TIME CORE IS ALLOCATED.
*P*               WHEN THE BOOT IS FROM TAPE, THEN THE ROUTINE
*P*               TBOOT: IS ENTERED. RECONFIG IS ENTERED TO
*P*               INITIALIZE THE DEVICE ADDRESS TABLES & TO
*P*               DETERMINE IF THE TARGET MACHINE IS THE SAME
*P*               AS THE SYSTEM BEING BOOTED. TBOOT: THEN
*P*               REQUESTS DEVICE ADDRESS CHANGES FOR THE
*P*               C,LL,DC (CARD READER, LINE PRINTER, SWAPPER(S)
*P*               RESPECTIVELY) IF CHANGES ARE NECESSARY. THE
*P*               SWAPPER(S) IS(ARE) THEN CHECKED TO DETERMINE
*P*               IF THE TARGET MACHINES SWAPPER(S) IS(ARE) THE
*P*               SAME AS THAT FOR WHICH THE SYSTEM WAS SYSGENED.
*P*               TBOOT: THEN INITIALIZES THE JIT & WRITES IT TO
*P*               THE SWAPPER. THE SYSTEMS VERSION & TYPE ARE THEN
*P*               INITIALIZED FROM THE MONITOR INFO RECORD FROM
*P*               TAPE. XDELTA IS THEN READ FROM TAPE. THE
*P*               SENSE SWITCH INFO IS DISPLAYED (IF DESIRED).
*P*               TBOOT: THEN ENTERS XDELTA FOR THE
*P*               READING & PROCESSING OF MONITOR ROOT & OVERLAY
*P*               & SPECIAL MONITOR PROCESSOR PATCH CARDS. XDELTA
*P*               MAY ALSO ENCOUNTER RECONFIGURATION CONTROL
*P*               COMMANDS, AT WHICH TIME XDELTA RETURNS
*P*               CONTROL TO BOOTSUBR WHICH INTURN ENTERS
*P*               RECONFIG FOR IT TO PROCESS THESE COMMANDS.
*P*               TBOOT: CONTINUES TO INTERFACE WITH XDELTA
*P*               UNTIL ALL OF THE MONITOR OVERLAYS & SPECIAL
*P*               PROCESSORS HAVE BEEN READ FROM TAPE & PATCHED
*P*               IF REQUIRED. TBOOT: THEN WRITES THE MONITOR
*P*               ROOT ON THE SWAPPER ALONG WITH A DISC BOOT.
*P*               BOOTSUBR THEN INITIALIZES THE REAL-TIME CORE
*P*               (IF A REAL-TIME SYSTEM) & THEN EXITS.

*F*               SEVERAL WAYS: COLD TAPE BOOT, BOOT TAPE UNDER
*F*               FILES, DISC BOOT, RECOVERY, OR OPERATOR RECOVERY.

*F*               REAL-TIME, THEN REAL-TIME CORE IS ALLOCATED.
*F*               WHEN THE BOOT IS FROM TAPE, THEN THE ROUTINE
*F*               TBOOT: IS ENTERED. RECONFIG IS ENTERED TO
*F*               INITIALIZE THE DEVICE ADDRESS TABLES & TO
*F*               DETERMINE IF THE TARGET MACHINE IS THE SAME
*F*               AS THE SYSTEM BEING BOOTED. TBOOT: THEN

*F*               C,LL,DC (CARD READER, LINE PRINTER, SWAPPER(S)
*F*               RESPECTIVELY) IF CHANGES ARE NECESSARY. THE

*F*               SAME AS THAT FOR WHICH THE SYSTEM WAS SYSGENED.
*F*               TBOOT: THEN INITIALIZES THE JIT & WRITES IT TO
*F*               THE SWAPPER. THE SYSTEMS VERSION & TYPE ARE THEN
*F*               INITIALIZED FROM THE MONITOR INFO RECORD FROM
*F*               TAPE. XDELTA IS THEN READ FROM TAPE. THE
*F*               SENSE SWITCH INFO IS DISPLAYED (IF DESIRED).
*F*               TBOOT: THEN ENTERS XDELTA FOR THE
*F*               READING & PROCESSING OF MONITOR ROOT & OVERLAY
*F*               & SPECIAL MONITOR PROCESSOR PATCH CARDS. XDELTA
*F*               MAY ALSO ENCOUNTER RECONFIGURATION CONTROL
*F*               COMMANDS, AT WHICH TIME XDELTA RETURNS
*F*               CONTROL TO TBOOT:   WHICH INTURN ENTERS
*F*               RECONFIG FOR IT TO PROCESS THESE COMMANDS.
*F*               TBOOT: CONTINUES TO INTERFACE WITH XDELTA
*F*               UNTIL ALL OF THE MONITOR OVERLAYS & SPECIAL
*F*               PROCESSORS HAVE BEEN READ FROM TAPE & PATCHED
*F*               IF REQUIRED. TBOOT: THEN WRITES THE MONITOR
*F*               ROOT ON THE SWAPPER ALONG WITH A DISC BOOT.
*F*               TBOOT:   THEN INITIALIZES THE REAL-TIME CORE
