BOOT TRACKS CONSTRUCTION FOR THE COMPUPRO
|
||
|
||
The loader, which resides on the system tracks, is created with
|
||
the following sequence of commands:
|
||
|
||
;; The following sequence of commands may be executed from
|
||
;; a SUBMIT file.
|
||
;
|
||
RASM86 DSKBOOT
|
||
;
|
||
LINK86 DSKBOOT.SYS=DSKBOOT[DATA[ORIGIN[0]]]
|
||
;
|
||
RASM86 LBIOS
|
||
;
|
||
RASM86 LPROG
|
||
;
|
||
LINK86 LBIOS3.SYS=LBIOS,LPROG[DATA[ORIGIN[180]]]
|
||
;
|
||
;; GENLDR will create the CPMLDR.SYS
|
||
;
|
||
GENLDR [NNNN]
|
||
;
|
||
;; NNNN:0000 is where cpmldr will be loaded at boot time, so be careful that
|
||
;; CCPM.SYS will not be loaded over your cpmldr.
|
||
;;
|
||
;; End of the SUBMIT file
|
||
|
||
Now read in the file DSKBOOT.SYS with DDT86 (this can't be done under
|
||
SUBMIT) and remove the header and base page. This will allow you to
|
||
merge this into the CPMLDR file.
|
||
|
||
A>DDT86
|
||
-RDSKBOOT.SYS
|
||
START END
|
||
aaaa:0000 aaaa:37f
|
||
-WBOOT,180,37F
|
||
-^C
|
||
|
||
Now merge the two files with the following command line:
|
||
|
||
A>PIP BOOTTRKS=BOOT[O],CPMLDR.SYS[O]
|
||
|
||
Assemble and link the track copy utility with the following commands:
|
||
|
||
A>RASM86 TCOPY
|
||
|
||
A>LINK86 TCOPY
|
||
|
||
The final step is to execute TCOPY under a version of CP/M-86 1.X.
|
||
|
||
****************************************************************
|
||
**** | Because TCOPY does direct BIOS calls, it will not | ****
|
||
**** | execute under any other operating system. | ****
|
||
****************************************************************
|
||
|
||
|
||
A>TCOPY BOOTTRKS
|
||
|
||
You should now have a system loader on the boot tracks that will
|
||
load a file called CCPM.SYS into memory and begin system ececution.
