Wow, that's kind of cool.
I suppose I shouldn't have been, but I was a little surprised to see that it's mostly (or entirely) asm files.
I don't know how useful it could be for importing any relevant portions into the ReactOS source tree, and I doubt it'll be all that helpful as a technical reference of what DOS does, as asm files don't really tell you much more than disassembling the binaries for yourself, however... there are at least some comments, which could potentially help in understanding what the devs intended in certain parts, so at least that's something.

But still, Microsoft releasing MS DOS under an OSI approved license (and especially one as permissive as the MIT license) is pretty cool in and of itself.
I reserve the right to completely ignore any portion of any post if I deem it not constructive and/or likely to cause the discussion to degenerate.

That is a bit old. It didn't start becoming good until 3.1 and mature by 5.x. Then there was a 6.x that I think was hyped, and 7.x that was intrinsic to Windows 9x.

ReactOS is still in alpha stage, meaning it is not feature-complete and is recommended only for evaluation and testing purposes.

Didn't MS DOS live until MS DOS 6.1? 2.0 would be a very very old and early DOS. Isn't there an open source freedos?

As a standalone product, yes. But I think Windows 95-ME had a DOS 7.1 packaged with it. The 6.1 or whatever was the last you could purchase by itself.

Yeah, but it's now more available, being on GitHub.

Yeah, it's been available since 2014, but not truly open source. Now it's MIT licensed, so if there would be any benefit to using it directly, ReactOS legally can now.

IIRC, it was available as a standalone product till 6.22, Win95 was built on 7.0, and later updated to 7.10, which Win98 was built on, then WinME had DOS 8.0 which tried so hard to be NT, but ... we all know how well Windows ME did.
