ISSUE:

Q.  Does Novell DOS 7.0 EMM386.EXE support backfilling?

A.  Novell DOS 7.0 EMM386.EXE does not support mapping of EMS pages
into anything else than the page frame (no backfilling, no additional
non-frame pages in the range C000-EFFF).


Q.  What is Backfilling?

A.  In 1987, the EMS standard was revised to version 4.0 ( LIM/EMS
4.0). This new specification incorporated some improvements that had
been added to LIM 3.2 by AST, Quadram, and Ashton-Tate in their
Enhanced Expanded Memory Specification (EEMS).  LIM 4.0 allows for
backfilling, the process of filling in conventional memory starting
at 640KB on down to 256KB and advising DOS of its presence.
