Doesn't make sense, but a lot of bugs and conflicts don't.   ;-)

I meant compile from scratch with DJGPP (and yes I actually built this
like a week ago):

iBiblio has a few file managers, e.g. at least three DOS Navigator
derivatives. You could also try Doszip, but (naively) perhaps Ytree
(clone) is more apt? Dunno. And there are dozens of other DOS file
managers out there.


If that doesn't help ... what specific feature does he need / want so badly?

Well, no, it probably wouldn't, but I see no reason for disabling it
except in rare cases.

That's somewhat surprising, but I guess nobody's perfect.

I just meant try "hdpmi16 -r", and see what happens. It should be okay
(famous last words). You probably? don't need the other stuff. At
least, HXRT.ZIP is probably enough.

The DPMI client grabs what it can, either from DPMI host, VCPI, XMS,
or raw. Depending on various factors, of course.

HIMEM.SYS is the typical one, yes, but FreeDOS uses HIMEMX.EXE these
days. XMGR.SYS is Jack's alternative. Jemmex is Jemm386 + HimemX
bundled together. EMM386 traditionally doesn't have XMS built in (but
DR-DOS' one does).

Mem isn't accurate in weird cases, things are complicated. I wouldn't
worry about that specifically. As has been proven in buggy NTVDM, you
don't have to report accurate numbers for things to (mostly) work.

Yes, there's a very slightly newer version, but I seriously don't
recommend JEMM386 "NOEMS". It might work, but I ran into several bugs
/ errors / incompatibilities with a few extenders (DOS/32A, D3X), so I
wouldn't totally recommend that setup. Easier to use JEMM386 LOAD
sporadically if EMS is needed.

Right. But even a P3 might have issues (e.g. soundcard).

Me either, but I doubt we can hold off forever.

No idea, just saying that "nobody" (heh) uses XKEYB, and Aitor's KEYB
is heavily preferred. Whether that fixes anything or works better for
you, dunno, but it's by far the recommended util for i18n keyboard
input (also thanks to Henrique). I just threw tom's mKEYB out there
just in case its minimalism worked where none others did (worth a
