It appears you're booting a DOS, so I would recommend xms=false, ems=false, umb=false settings, although it may make no difference. You could try changing the core and cputype settings.

I've not had any luck making QEMM386 or 386MAX work with a DOSBox image.

Getting memory managers to run is not exactly the goal of the DOSBox project. The reason for DOSBox's existence is to be able to play games. I very much doubt that this is ever going to be supported. It might help if you tell us what exactly you're trying to do or which application you're trying to get working.

You should have no need to do this that I can think of, unless you have some specific example game that requires it.

QEMM filled two primary roles for most DOS users: it provided a DOS advaned memory API (protected mode/ems/xms) and attempted to remap used areas of the DOS stack into the 384K "high memory" region above regular DOS mapping.

DosBox effectively does both of these already. If you notice on a fresh invocation of dosbox, the free memory stack for DOS apps is more than you would ever see at a real DOS prompt (with stock .74, 632 kb free while already providing 63k in a high block and xms/ems).

So basically...why are you doing this? Dosbox can provide the services that QEMM provided much more efficiently.

Thank everyone for answers!
to ripsaw8080: I tried these settings for xms, ems, umb, core and cputype. You are right - no difference.
to valnar: You think it doesn't supported? But I saw in the different branches the advices to install qemm to the dosbox.
to dada: All that I did it installed DosBox, installed MS Dos and Qemm on it. (I had to install MS Dos, because Qemm asked the config.sys file, and as I know single DosBox doesn't have it). And after that DosBox with Ms Dos no longer boots.

frobme, I do it for old application which worked in the real DOS system. This app needs the memory and some "task manager", that Qemm have. That why I need Qemm on the Dos.

By "task manager" do you mean DESQView? Have you tried running it in DOSBox without booting DOS? I guess it's understandable that DESQView would insist on QEMM, as they're both made by Quarterdeck.

yes, I mean DESQView. I had to install MS Dos, because Qemm asked the config.sys file, and as I know DosBox doesn't have it.

There's no game I know of that requires DesqView. If you are trying to run BBS software or something like that which does require it, you'd be much better off using a virtual machine emulator (VMware, VirtualBox, etc).

I doubt Dosbox will be the best choice here, because instead of striving to replicate the underlying hardware behavior exactly, it instead tries to create the highest performance environment consistent with how Dos *games* run. However if you want to keep trying with Dosbox I would try setting UMB, XMS, and EMS to false in the config file, then installing DOS itself, and after that QEMM.

As already indicated DOSBox is currently focused on supporting DOS games, not utilities or window managers. Due to that, you are likely better off using a different VM. VirtualBox (http://www.virtualbox.org/) is also free, and would likely provide a better experience for your purposes.

Thanks for answers!
I am going to run not the game. It is a industry code, written in the early 90s. But this code requires qemm (more memory and multitasking), network and graphics.
I tried VB and many other virtual machines, but with one result - it all hangs after install qemm. I thought that it because almost all VM not emulates the processor (the 0-ring commands goes to the real processor without emulating).
And qemm does not run, because, as I understand, it uses instruction for jump to protected mode.
But I heard that DosBox fully emulates the processor.

You could try either QEMU or Bochs, both of which are attempts to fully emulate a processor (not virtualize it). There are some google results of people getting QEMM running under Virtualbox, just not version 7.5.

Thank you for advice. I will try install qemm on the Bochs (I tried to use QEMU and VB)

As I understand, it is impossible at all to run qemm on the dosbox, and I can finish any attempts to do it. Right?
