I've not used it.  I looked at it a few years ago.  Some issues kind of made
me back off, such as the license, binary patch updates, and difficulty
determing what to download, or if I needed to apply numerous patches ...

But, the code is open source, and it is 100% compatible with MS-DOS up to a
certain point because of a lawsuit with Caldera.  Apparently, MS was
required to provide whatever information was needed for DR-DOS to be 100%
compatible for a ten year period from 1996 (e.g., to 2006):

Gates declared MS-DOS dead after releasing XP in 2001.  If Caldera kept up,
that should cover everything upto the final version of MS-DOS, v8.0 that
came with ME.  So, OpenDOS/DR-DOS should be a good for reference info on DOS
internals.  Since MS-DOS is dead, other DOS' can improve as they see fit
without needing to be MS, or IBM, or Caldera etc compatible.

IIRC, DR-DOS also had a good .pdf on their DOS with a section on
writing DOS device drivers.  I'm not sure anymore if it that was on the
OpenDOS or commercial DR-DOS website.  I don't see it on either.  Let me
search ...  Nope, memory fades, the .pdf is for PC-DOS 7:
