PS/MS-DOS does not, nor can it ever, access anything except the first 1 MB
of memory.  The first 640K being RAM and the rest being various hardware.
DOS is designed for the lowest common chip, the 8088, which only knows 1MB.

Even if you run Windows/386, DesqVIEW or VM/386, the DOS partition that is
created can only run like an 8088, ie, 640K of user memory for programs.

The only way to get more is to run OS/2 and applications designed for OS/2.
