-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft MS-DOS operating system versions 5.0, 5.0a, 6.0, 6.2, 6.21, 6.22 
- Microsoft Windows versions 3.1, 3.11 
- Microsoft Windows for Workgroups versions 3.1, 3.11 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you use the EMM386.EXE exclude switch X=MMMM-NNNN, you may receive the
following error message:

  WARNING: User Specified Ranges Overlap.
  Press any key when ready...

For example, this error message can be generated with the following CONFIG.SYS
file command:

  device=c:\dos\emm386.exe x=F000-FFFF

CAUSE
=====

This error occurs when the ranges you are including and excluding overlap, or
when you attempt to exclude memory in the ff00-ffff range.

RESOLUTION
==========

To eliminate the error message, exclude a range below ff00 and ensure the ranges
you are including and excluding do not overlap. The largest range you can
exclude is A000-FEFF.

MORE INFORMATION
================

The F000-FFFF range is not included in the EMM386.EXE search algorithm. If you
are using EMM386.EXE version 4.45 or later, you can have EMM386.EXE search this
range by adding the HIGHSCAN parameter. The F000- FFFF address range is
typically occupied by the System ROM BIOS.
