MS-DOS: #Config.sys und #Autoexec.bat für viel freies konventionelles RAM

Kategorie "verlorenes Wissen":
Viele alte Spiele unter MS-DOS benötigen oft freien konventionellen Speicher (RAM) in den unteren 640 Kb, selbst, wenn das System über mehrere MB im sogenannten oberen Speicherbereich verfügt.

Beispiel:
"Dune II - Battle for Arrakis" benötigt laut Handbuch 564 Kb konventionellen Speicher.

Hier ein kleiner Artikel, wie das zu erreichen ist:

Update: Workaround found (see bottom of post)...

DOS folks, I have been trying to figure out why my Gravis Ultrasound soundcard is not behaving with a new boot volume, and I have narrowed it down to the loading or not-loading of a DOS CD-ROM driver (only produces sound when driver is loaded(!)). This makes no sense to me.

I have just boiled down the synopsis and listed the autoexec.bat and config.sys sections in this post on my thread. I'd appreciate any help I can get, here. So odd...

**UPDATE/EDIT: Well, it makes no sense but the issue is resolved. (IRC screenshot)
