Hey,
i am trying to use Desqview with QEMM in Dosemu with Freedos.
I tried QEMM 9 (97) and QEMM 8 and it does not load correctly. It says
it needs
at least a 386 CPU, so it seems QEMM does not recognize the CPU the way
it should.
I have never attempted to run QEMM under dosemu. Here are some pointers
that I think might help, though.
(1) the last versions of QEMM were also meant to work with Win95 and, to my recollection, were buggy. I cannot remember which version I last used with Desqview, but I am pretty certain the version released in 1997 was one of
the "and Win95" versions. Might try an earlier version. I have a machine
with DV still installed but it is not hooked up to anything right now or I would check my versions for you.
(2) you probably already did this, but be sure your dosemu.conf is
emulating a 386 or 486.
(3) this last one is a not good one... QEMM might not be compatable with versions of dosemu and, more imporantly, the linux kernel that are new
enough to have done away with DPMS (DOS Protected Mode Services)
compatability. IIRC, that went away with linux 4.x. As an example, I have
to run my DOS BBS in a VM running a 3.16 kernel and what appears to be a
2013 version of dosemu. Things it depends on don't work on linux 4+
machines, or with the newer dosemu release(s).
Anyone has experience with this combination? is there maybe a different version of QEMM working with Dosemu/Freedos? Or is there a
configuration option that can make it work?
Like I said, I have never tried but would be interested to know if you get
it working.
furthermore, does dosemu use one cpu core only always? Am i bound to
the performance that one cpu core can deliver?
Or makes using Desqview in this context no sense at all? Better start Dosemu 2 times?
As far as I know, it only uses one cpu. Even if dosemu will, or does, use
more than one cpu, I somehow doubt QEMM/DV would recognize that.
As an aside, there was a recent article linked on osnews.com about DV/X. My recollection is that DV/X also depends on QEMM. I read the article a week
or two ago, but I got the impression that maybe the person who wrote the article was running DV/X (and therefore DOS) in a VM on a linux machine, so they must have gotten it working somehow if I am remember it right.
You might check osnews.com and look for that DV/X article.
