- Microsoft FoxBASE+/386 for MS-DOS 2.1
This article was previously published under Q101155
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.
