This file explains how to install the 4DOS/NT 2.0 rev B patches.
To use the patch, you must have:
* JP Software's PATCH.EXE program. This program is in a separate
file, PATCH.ZIP on CompuServe, or 4DPATCH.ZIP on bulletin boards
and the Internet. [* See note below.]
* A copy of 4DOS/NT 2.0 rev A. The simplest way to check your
revision level is to use the 4DOS/NT VER /R command.
To use this patch, copy the 4NT20C.RTP file to the directory where your
4DOS/NT version 2.0 files are stored. Make sure JP Software's PATCH.EXE is
in the same directory, or in a directory on your PATH, then enter the
This patch converts 4DOS/NT 2.0 rev A to version 2.0 rev B. It modifies
only 4NT.EXE, all other files are unchanged from rev A. Branding (name
and serial number) information in your 4NT.EXE file will be preserved in
the modified file.
If you want to test 4NT.EXE to make sure the patch worked, restart your
4DOS/NT window, use the VER /R command. This command will report
"4DOS/NT Revision A" (if the patch did not work) or "4DOS/NT Revision B"
(if it did work).
If you are short on disk space and receive a message that there is not
enough space to perform the patch, you can use a command like this to
reduce the disk space required:
patch /noundo 4nt20b
This will make recovery slightly more difficult in the unlikely event of
a power failure or similar problem during the patch process, but will
reduce the disk space required to perform the patch.
4DOS/NT version 2.0 revision B includes only minor internal changes to
version 2.0 revision A.
