Sorry, I don't know this software. But in general, if you're getting
memory errors there's a multitude of possible reasons and since
DR-DOS provides much more features than MS-DOS how to optimize the
memory configuration, it might be more difficult, if you're new to
the configuration switches provided by the DR-DOS memory managers.
A good thing to start with is to disable EMM386's support for
DPMI and multitasking: /DPMI=off /MULTI=off. You can also try
to exclude a larger region of upper memory from usage as UMB.
Also try to disable usage of the video memory address space
/VIDEO=off. Depending on your AddOn adapters moving the EMS-page
frame (if you are using EMS) may help too.
If any of this helps, it does not mean, you would have to permanently
disable these features, but it's good to isolate the cause for
the problem.
Try HIMEM.SYS instead of EMM386. If you have access to it, it
cannot harm to try MS-DOS HIMEM+EMM386 for troubleshooting (but
many of the switches are different). Try to change the load-high
order of resident drivers, try to subsequently not load high
TSRs, and eventually remove them.
Knowing the results of these tests, we might be able to find a
working configuration, that is still feature-rich and optimized.

PS: I think it's time to wish all the remaining DR-DOS fans
a Merry Christmas, peaceful holidays and good luck for
the year 2000 and beyond.
My personal hope regarding this list is, that the next year
will bring some new action into DR-DOS' life - even on the
desktop. We don't need to worry for Linux, this steam hammer
is unstoppable now.
I speak only for myself, but I think, opening (some of) the
DR-DOS sources to the public could cause a prosperous
technology exchange between Linux and DR-DOS (and FreeDOS),
whereby all could only profit - DOS isn't that old fashioned,
as some people think. Multi-millions of people use it every
day without knowing it...
There's a proverb in Germany: "Alle kochen nur mit Wasser."
[Everyone uses water for cooking.] I for myself have
(almost) ready many system extensions for (DR-)DOS, which
I would like to polish for publishing once DR-DOS would
have become really open...
