That's exactly what MSDOS does with the setver program, it lies to
programs to tell them they're a different version of dos just so that
they will run properly.
Not to mention, the tiny (something less than 100 bytes) tsr that AMD
had to write when windows stopped working on anything but intel
processors. MS claimed it was a fault in the AMD processors, but AMD
made a TSR that told windows that they were running on MSDOS, and it
worked just fine.
So, yes, what you're asking is 100 percent doable. Whether there's an
actual equivalent for FreeDOS though is a different question.
For what it's worth, I don't know of anything that does this, but I'm
hardly the DOS afficianado.

Not sure if this is possible or even how some programs may work.
I work in FreeDOS in virtual PC 2007 and I am tryin to use fshare
which allows shared folders in VPC but it tells me that "folder
sharing on this host is not allowed" which makes me think it expects
msdos but is gettin freedos instead. Is there a way to have the
system temporarily report as msdos instead of freedos, or a way to
have programs see the system as msdos and not freedos?
I think this may help in gettin more software to work in FreeDOS.
Just my opinion and I could be wrong.
Could anyone enlighten me on this and their opinions? Thank you.
