Microsoft MS-DOS 2.00

There was no MS-DOS 2.00 product per se. Instead, there were OEM releases of MS-DOS based on version 2.00, including:

MS-DOS 2.00 Source Code

On March 25, 2014, the source code upon which OEMs based their MS-DOS 1.x and 2.x releases was made available to the public by the Computer History Museum, with the permission of Microsoft.

![MS-DOS 2.00]({{ site.demo-disks.baseurl }}/pcx86/dos/microsoft/2.00/MSDOS200-DISKS.jpg)

Unfortunately, the Computer History Museum decided not to share the precise contents of the diskettes in its possession. Instead, they released a ZIP archive that aggregated the contents of the MS-DOS 2.x diskettes into two folders, v20object and v20source, with no clear indication which files came from which disk, why some files were renamed (and what the original names were), and what (if anything) was omitted.

To add to the confusion, some WordStar 3.20 binary files were included in the v20source folder, completely unrelated to MS-DOS--and also completely useless, since the main executable, WS.COM, was not included.

Finally, it isn't entirely correct to describe these files as the source code for "MS-DOS 2.0". It's actually a much later snapshot of source code, used to build MS-DOS 2.11, so at best, the collection should be referred to as "MS-DOS 2.x".

UPDATE: On September 28, 2018, Microsoft re-released the MS-DOS 1.x and 2.x source files on GitHub. The files are identical to the original CHM release, so no effort was made to improve the previous release, remove irrelevant files, organize them by original diskette, etc. And while GitHub is a great way to save and share files, Git repositories don't preserve original file modification dates and times, unfortunately.

Microsoft's sole improvement of the 2018 re-release was to quietly relax restrictions on the reuse of the source code, by releasing it under an MIT License, instead of the older and much more restrictive Microsoft Research License Agreement.

Building MS-DOS 2.x Source Code

For the machine below, a 10Mb hard disk image was created with all the MS-DOS 2.x sources:

diskdump --dir=src --format=json --output=MSDOS2X-SRC.json --label=MSDOS2X --size=10000 --normalize --overwrite

The source files were copied from the CHM release, only because they had preserved the original file timestamps:

Next, all the source files were organized into folders corresponding to their respective binaries, along with makefiles where appropriate (eg, MSDOS.MAK). Also, in the INC folder, DOSMAC.211 was copied to DOSMAC.ASM, and DOSSYM.211 was copied to DOSSYM.ASM, since the rest of the sources are for MS-DOS 2.11 as well.

Then the MSDOS folder was supplemented with reconstructed IO.ASM and IO2.ASM files from John Elliott.

The resulting files, along with a MK.BAT batch file, were installed in the machine below on drive D. Drive C contains a bootable copy of PC DOS 2.00, along with Microsoft MASM 4.00 and other assorted tools.

If MK.BAT is invoked with the name of one of the folders (eg, MK COMMAND), it will run MAKE in that folder; to build all the folders, use MK ALL.

MK.BAT also accepts optional "OEM" and "VER" parameters. For example, MK MSDOS IBM 200 will build the MSDOS folder with symbols OEMIBM and VER200 defined. Over time, the PCjs Project will use those symbols to tweak the source files, in order to produce binaries that match the corresponding original release.

DOSSYM.ASM has been modified to check for "OEM" and "VER" symbols, and to display messages indicating the current build selection, alerting you that the resulting binaries may differ from those produced by the original source code snapshot.

For example, files built using MK ALL IBM 200 should display these messages:

IBM release selected 
VERSION 2.00 selected

However, you will sometimes see these messages:

IBM release pre-selected 
VERSION 2.00 selected

which means that another file, such as COMSW.ASM or STDSW.ASM, defined IBM before including DOSSYM.ASM. And sometimes a file will set IBM itself, such as GETSET.ASM. The "pre-selected" messages help you catch any build discrepancies due to these oddities.

Other files have been modified here as well, primarily to eliminate extraneous characters that caused warnings or errors during the build process. Which raises the question: which version of MASM was originally used to build these sources? The MASM.EXE that was bundled with this snapshot is dated Feb 1, 1983 and reports:

The Microsoft MACRO Assembler
Version 1.10, Copyright (C) Microsoft Inc. 1981,82

However, it's rather buggy, so it almost certainly was not used. For that matter, it's unclear if this snapshot of MS-DOS 2.11 represents a finished product or a work-in-progress. Sadly, no one at Microsoft seems interested in finding or sharing the answers.

MS-DOS 2.x Build Machine

A quick note about speed: the typical PC in the early 1980s was still a 4.77Mhz 8088-based machine, so it took a considerable amount of time to assemble all the MS-DOS 2.x sources. If you're impatient, you can load the machine on this page with a higher speed multiplier (eg, multiplier=8) or click the Speed button below until it's running at speed that you prefer (and that your browser supports).

In addition, all the build products (OBJ, EXE, COM, LST, and MAP files) from a successful MK ALL command have already been saved in the pcjs-disks repository, in the /pcx86/dos/microsoft/2.00/built folder.
