- ; ZEX 1.0 Installation ZEX File, 11-12-82, by Richard Conn
- ;
- ; You will need the following files in order to assemble ZEX:
- ; MAC.COM ZSID.COM ED.COM RELS.UTL
- ; Type <CR> if you have them on this disk or type ^C to abort -- ^/
- ;
- ; ^*ZEX 1.0 Installation Begins^*
- ;
- ; 1. ERASE ANY FILES FROM PREVIOUS .SUB EXECUTIONS
- ;
- ERA ZEX*.BAK
- ERA ZEX*.HEX
- ERA ZEX*.SYM
- ;
- ; 2. USE CPM 2.2 XSUB (not required if using previous version of ZEX)
- ;
- ;XSUB
- ;
- ; 3. CREATE ZEX10.LIB FOR ASSEMBLY OF ORG 0 RELOCATED CODE SEGMENT
- ;
- ED ZEX10.LIB
- #A
- #K
- I
- BASE EQU FALSE ;SUPPRESS ZEX INITIATOR CODE (ENABLE RELOCATED CODE)
- REL EQU 0 ;SET RELOCATED CODE SEGMENT TO ORG 0
- ^Z
- E
- ;
- ; 4. ASSEMBLE ONLY ORG 0 RELOCATED CODE SEGMENT
- ;
- MAC ZEX $$PZ
- ;
- ; 5. RENAME STEP 4 FILES
- ;
- REN ZEX100.HEX=ZEX.HEX
- REN ZEX100.SYM=ZEX.SYM
- ;
- ; 6. CHANGE ZEX10.LIB FOR ASSEMBLY OF ORG 100H RELOCATED CODE SEGMENT
- ;
- ED ZEX10.LIB
- #A
- #K
- I
- BASE EQU FALSE ;SUPPRESS ZEX INITIATOR CODE (ENABLE RELOCATED CODE)
- REL EQU 0100H ;SET RELOCATED CODE SEGMENT TO ORG 0+100H
- ^Z
- E
- ;
- ; 7. ASSEMBLE ONLY ORG 100H RELOCATED CODE SEGMENT
- ;
- MAC ZEX $$PZ SZ
- ;
- ; 8. RENAME STEP 7 FILE
- ;
- REN ZEX101.HEX=ZEX.HEX
- ;
- ; 9. CHANGE ZEX10.LIB FOR ASSEMBLY OF ZEX INITIATOR CODE ONLY
- ;
- ED ZEX10.LIB
- #A
- #K
- I
- BASE EQU TRUE ;ENABLE ZEX INITIATOR CODE (SUPPRESS RELOCATED CODE)
- REL EQU 0 ;RESET RELOCATED CODE SEGMENT TO ORG 0
- ^Z
- E
- ;
- ; 10. ASSEMBLE ZEX INITIATOR CODE ONLY
- ;
- MAC ZEX $$PZ
- ;
- ; 11. USE SID AND RELS.UTL TO CREATE ZEX.COM
- ;
- ; [note: If only REL.UTL is available, comment out the lines
- ; starting with IZEX.COM below and change the line
- ; SID RELS.UTL to SID REL.UTL and a SAVE 10 ZEX.COM
- ; must be added at the end of this file.]
- ;
- ; ZEX.HEX contains ZEX Initiator Code
- ; ZEX.SYM contains symbols for SID for ZEX Initiator Code
- ;
- ; ZEX100.HEX contains ZEX ORG 0 Relocated Code Segment
- ; ZEX100.SYM contains symbols for SID for ZEX ORG 0 Relocated Code
- ;
- ; ZEX101.HEX contains ZEX ORG 100H Relocated Code Segment
- ;
- ; BEGREL is the symbol for the start of the Relocated Code
- ; Segment in ZEX.COM
- ;
- ; DRVERL is the symbol for the length of the Relocated Code
- ; Segment
- ;
- ; DRVL8 is the symbol for the length of the storage required
- ; for the relocation table bit map to be created by
- ; RELS.UTL
- ;
- ; RELOCL is the symbol for the DW in ZEX.COM that will contain
- ; the length of the Relocated Code Segment
- ;
- ;
- ; A. SID is invoked and the .SYM files for the ORG 0 Relocated Code
- ; Segment and the Initiator Code Segment are loaded.
- ;
- ; B. The DW at symbol RELOCL is updated with the value of DRVERL
- ; from the ORG 0 Relocated Code Segment.
- ;
- ; C. Memory for the two copies of the Relocated Code Segment
- ; (ORG 0 and ORG 100H) and the relocation table bit map is zeroed.
- ;
- ; D. The ORG 0 Relocated Code Segment is loaded starting at
- ; location BEGREL.
- ;
- ; E. The ORG 100H Relocated Code Segment is loaded after the
- ; segment loaded in step C plus the length of the relocation
- ; table bit map.
- ;
- ; F. RELS.UTL routine SETADRS sets the starting addresses of
- ; the two Relocated Code Segments for creation of the relocation
- ; table bit map.
- ;
- ; G. RELS.UTL routine SETLEN sets the length of the Relocated
- ; Code Segment and builds the relocation table bit map.
- ;
- ; *H. RELS.UTL routine SAVE saves the EX Initiator Code Segment,
- ; the ORG 0 Relocated Code Segment, and the relocation table
- ; bit map created by RELS.UTL.
- ;
- ; * [note: not used if only REL.UTL is available]
- ;
- ; I. CP/M is returned to by G0.
- ;
- ; **J. SAVE 10 ZEX.COM saves the ZEX Initiator Code Segment,
- ; the ORG 0 Relocated Code Segment, and the relocation table
- ; bit map created by REL.UTL.
- ;
- ; ** [note: used ONLY if REL.UTL is used]
