Issues when running DR-DOS 7.03 MEM.EXE

[boeckmann]

When running DR-DOS 7.03 MEM.EXE while booted under EDR-DOS kernel, two issues arise:

1. MEM shows an impossible memory size for the DOS
2. MEM cannot peek into high memory

Both of these issues do not occur on the DR-DOS 7.03 kernel. The second one may be because the EDR kernel does not setup a MCB chain for the high memory area (not yet sure DR-DOS 7.03 kernel implements it, but would be an explanation).

Regarding the first one a have no idea right now what might be the cause (see screenhot). Maybe just an incompatibility between the kernel and MEM.EXE. But maybe something more serious...

Flawed output when running EDR kernel:

This also affects the OpenDOS 7.01 MEM.
