Sure. But... Even with loading and keeping all that stuff, the system still has 94K free upper memory and 84K of that is consecutive. Unloading those drivers would not free up the 11K of Low memory used by the Kernel. It would just free upper memory of which there is plenty. The largest executable size is 628K. Nothing should every require over 600K of low memory to load. I would just like to see all ZEROs in the middle column. It also wouldn’t hurt to get another 10K added to the largest EXE that can be loaded. Actually, that MEM print out is outdated for that machine. Just to use up some more upper memory, it now loads CWSDMPI at boot. That brings free upper memory down to about 45K. But if upper memory gets too low or their are compatibility issues, I’ll stop loading it at boot. Side Note: At boot, the system transfers the main OS files over to RAM disk, reconfigures the environment accordingly and primarily runs from RAM. Much better performance. A lot less wear and tear on 25+ year old drives. Besides, it has got to do something with all that RAM under DOS. :-) Jerome _______________________________________________ Freedos-devel mailing list Freedos-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-devel
