MaxThink outliner crashes dosemu 1.1.99.1

MaxThink outliner crashes dosemu 1.1.99.1

[Ralph Alvy]

Is there some way to get MaxThink (a popular DOS outline) to work with
dosemu 1.1.99.1? Here's the error message I get when it crashes dosemu:

The short answer is No.
The long answer is... Yes, and is many ways.
Please refer here:

Well, I read those links and don't understand what I might do to make
MaxThink work with dosemu. Doesn't sound promising.

Here's what I just got from MaxThink's author:

Many years ago I added a memory extender to dos maxthink so it would run
outlines larger the 640 k.  That memory extender is what makes dos maxthink
not run under linux.

The first link gives you the clue that your program
uses a Blinker 3.20 extender.
The second link is a discussion about the
incompatibilities between dosemu and Blinker 3.20 
extender, and the ways of solving it.
The easiest thing mentioned there, is to start the
program from a "DOS Shell" of some DPMI program, for
example bc.exe (Borland C IDE), or by DJGPP's make by
writing a trivial makefile.

That's bad:)

True, but the workaround is trivial.

I'm not sure what a DPMI program is. Is it simply a program that uses DPMI?
Or do you mean something more than that?

Okay. I found a program that seems to use DPMI, which I assume is what
you're suggesting I do. That's Boxer TKO edition, which is the edition of
Boxer text editor that allows editing of files exceeding 640k. It has a DOS
shell in it. This version of Boxer does indeed load in dosemu, and its DOS
shell allows me to load MaxThink.

Thanks.
