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

- Microsoft FoxBASE+/386 for MS-DOS, version 2.1 
-------------------------------------------------------------------------------

SYMPTOMS
========

The following error message may occur when you try to start Microsoft
FoxBASE+/386 version 2.1 for MS-DOS:

  A20 Hardware Error

CAUSE
=====

This error is not caused by a hardware problem; it indicates that the
FoxBASE+/386 program is not compatible with the MS-DOS HIMEM.SYS device driver.

RESOLUTION
==========

Removing the HIMEM.SYS driver from the CONFIG.SYS file eliminates the message
and allows FoxBASE+/386 to load.

NOTE: The HIMEM.SYS driver, which is provided with some versions of MS-DOS,
manages the use of extended memory. It is added to the CONFIG.SYS file when
Microsoft Windows is installed. The HIMEM.SYS driver is necessary to run
Microsoft Windows.
