IBM was the first ever licensee of MS-DOS. It was built for IBM, and
as such, it has a degree of influence and control over every single
version. I am not aware of any particular way that this changed in
3.1. What do you have in mind?
It changed in 3.1 because of the contract they signed to produce OS/2.
This is the same time that you see two things happen with MS-DOS:
1. The standard generic version starts becoming IBM-compatible. (While
the common history says this happened with 3.2, you can see clear evidence
that this actually happened partway into the 3.1 cycle instead.)
2. IBM's version starts openly displaying both IBM and Microsoft
copyrights; prior to 3.1, only IBM copyright was displayed.
emm386 was originally developed by Compaq, and was in MS-DOS 4.
Compaq wrote CEMM, not EMM386, but I think that the Compaq one was
developed into the MS one, yes. OTOH since Compaq no longer exists MS
did not need to seek its permission in 2024, I think... no?
It seems to me, that more so than EMM386 being simply derived from CEMM,
EMM386 _is_ CEMM.
Also, Compaq does still exist - as part of Hewlett-Packard. Rights always
go somewhere when a company is acquired.
That's baroque when http://www.seasip.info/Gem/Software/resdir.zip exists
(the postprocessor I was referring to).
I disagree.
1. It's much preferable to just fix it. It merely needs a couple of
config files editing.
That's literally what the program does, except that the config file it
edits is binary.
2. One DOS command is easier than downloading a separate tool and
patching a program.
-uso.
