The only option is memsize=63 in the config file ("DOSBox Preferences" by default. While 63 is the highest possible value.

Is there a way to increase conventional memory allocation in dosbox?

DOSBox has too much already.

Try using LOADFIX [FILENAME.EXE].

DOSBox has almost all 640 KB Convential Memory available, and some applications only expect 576 KB to be available.

Failing that try installing real MS/PC DOS into DOSBox, and perhaps use QEMM if you're using Desqview.

Loadfix -576 filename.exe, I think. 😉

ouch then noting is left 😉
the parameter is the amount to decrease it.

Desqview was kind of windows 3.x env I recall. I did some debugging on it once and it's currently not very compatible with dosbox.

Desqview was a pre-emptive multitasking environment that ran every individual 'window' or task in 286 protected mode.

The problem with stuff like that is that they usually do a lot of dos table
copying, and dosbox has some stub tables or keeps data in private memory.

So the best thing to do is booting some real dos inside dosbox, but that
might not really be what you want to do...

Why would anyone want to run Desqview in DOSBox? dazza1554: what is the reason you want to to run Desqview, inside DOSBox, or even at all? AFAIK, there are no applications written specifically for Desqview.

I've had my share of experiences back in the day with Desqview, and from what i can remember, it never worked like it was supposed to. I tried to run a multinode BBS (PCBoard) with Desqview, but there were always problems with the memory, lockups, etc. I remember that the company that made Desqview (i think the same guys that made Qemm) stopped development of the application, leaving users "in the cold" with a not-really-working application.

Quarterdeck actually kept developing Desqview well into the late 90s and it was later sold as part of Banking software.

Damn, i'm getting old - i don't know when i really stopped using the product, out of sheer frustration. (; The Wikipedia article doesn't say until when Desqview was updated, but i remember being quite frustrated that the many quirks and errors of the software wouldn't be fixed.

Banking software?! Are you sure about that? AFAIK, financial institutes have always preferred client/server applications (where the server would run on machines like the AS/400), or OS/2, because of its real-time performance. I can't believe anyone would run a mission critical application with Desqview. (; Maybe you mean DESQview/X, which is quite different from Desqview.

Yep I'm sure, I worked for a company in 97 that sold it as part of their package to banking institutions. Yes, it was used for client server stuff - think opening 4 terminals on one machine - kind of a thin client application.
