DOS 2.5 patch for HomePak
-------------------------
PATCH.OBJ will patch a copy of your master HomePak disk to fully
support DOS 2.5 and its Ramdisk software. Note that the programs as
supplied will read and write files to drive 8. The only thing you
can't do is get directories, and that is what these patches entail.
The programs that need to be patched are HOMETERM and HOMETEXT.
(There are no directories in HOMEFIND so it's okay as is.) First
thing you need to do is to make a "J" copy of your master HomePak
disk. If you've previously made changes to any of the files (such as
via the HomeTerm Customizer, or by copying any of the HomePak files
to another disk) this patch utility might not work. In that case,
see the appendix for an alternate patching method.
PATCH.OBJ is a binary load file. (Portions of PATCH.OBJ use the
Action! run-time package, copyright ACS.) Load the program by using
the "L" option from the DUP.SYS menu.
Once the program has loaded, you'll be prompted to put a <COPY> of
your master HomePak disk in drive 1. Once you've done so, press the
[RETURN] key, and when it says "Done!" you're all finished. Boot the
new disk as normal and you now have directories for drives 1-8.
If you get the error message:
Expected byte incorrect-nothing done.
then PATCH.OBJ didn't find the bytes it was looking to patch. In
that case:
APPENDIX
--------
If PATCH.OBJ gives you errors, or you've modified the HomePak
programs as described above, then you'll be reduced to patching the
files directly using a sector editor, such as SHERLOCK or DISKEY.
