I normally run QEMU under Windows (64-bit, 3.0.0), but my main rig's
HDD is failing (S.M.A.R.T. error), so that's out of the question at
the moment.

I do also have it on my laptop (32-bit, 3.0.0), but even that old HDD
is somewhat slowing down. I could maybe try it later, but I somehow
doubt Windows builds are having the same quirks as your Mac build
(64-bit?).

Have you tried VirtualBox instead?

So QEMU 3.1 is apparently in release candidate, maybe they fixed it?? Dunno ....

Long story short: we no longer have any newer drivers for this kind of
thing. Oddly, though, and I'm not exactly sure why, FreeDOS shipped
older drivers (2013) when we do actually have a newer version circa
2015 (UIDE):

It's unsupported, but you could definitely try the newer version, and
see if that somehow fixes things for you. Somewhat of a long shot, but
that's my naive guess. (To be fair, there are even newer closed source
versions, but it's a big hassle: can't be redistributed, etc.)
