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...
