Interesting enough for there to be three topics about it already

and the only positive tech news as of late, coming from Microsoft of all places...

We might need it, though, to travel back in time and help John Titor hack the Gibson. 😎

There must still be things in later DOS releases that MS doesn't want the public to know about or else they would have released those as well. I know Apple can't release some of the early versions of MacOS as freeware because some of the code they used was licensed from other sources and is still under copyright. In order for Apple to release that code, they would first have to acquire it and I doubt they would spend money on something they intend to release for free. Maybe MS used code that wasn't generated in house in some of those later releases, either with or without permission.

So obviously this combination is not allowed: To derive a customized DOS from the source AND distribute that. Regardless of it being non-commercial.
...Bummer.
No interesting things to share, if you want interesting things you have to make it yourself and keep it solely for yourself.

Even these versions aren't complete... 1.1 is just a random selection of a few files, and 2.0 is missing io.sys source (for one).

Maybe the FreeDOS team can use some of the code to improve their version of DOS, like getting Windows to run over it, for example.

One highlight from the code:

; DS=CS. Writes back all dirty FATs. All registers destroyed.

Dirty FATs? Yes please.

I was more amused with lines 165-167 in v20source\FIND.ASM...

Please read from the link Stiletto posted. Someone mentions in there that the code cannot be compiled as-is. Someone from MS deliberately broke it. A few clever guys figured out some of the things they did to make the code useless and fixed it, but I'm sure there's a lot more that will need correcting before you can get a working copy of DOS from the sources. There's also parts missing, so getting a fully working copy from the sources may be impossible.
