SUMMARY
• Q. I receive the message "ERROR: Unable to control A20 line"
during the startup (boot) process. How can I correct this
problem?
A. The A20 line is a hardware component of 80286 and higher
processors that allows programs to access the first 64
kilobytes (K) of extended memory. HIMEM.SYS must be able to
control the A20 line to manage the extended memory on your
computer. Different computers use different techniques for
controlling the A20 line. In some cases, HIMEM.SYS cannot
determine the correct technique to use. If HIMEM.SYS cannot
identify the correct technique for controlling the A20 line on
your computer, you may need to use the /MACHINE switch with the
DEVICE=C:\DOS\HIMEM.SYS command in your CONFIG.SYS file. For
further instructions, refer to the "Diagnosing and Solving
Problems" chapter of the "Microsoft MS-DOS 6 User's Guide." You
can also type HELP HIMEM.SYS at
the MS-DOS command prompt and press ENTER for information on
HIMEM.SYS and the /MACHINE switch.
• Q. I'm using custom menu colors with multiple configurations.
During the startup process, my menu colors change back to the
default screen colors. Why is this occurring?
A. When ANSI.SYS is loaded, it resets your screen colors. ANSI.SYS
is an enhanced console device driver; therefore, it takes over
all output to the console. At this time, no workaround is
available for this problem.
• Q. How do I add the Windows(TM)-based utilities after I install
MS-DOS 6.0?
A. The MS-DOS 6 Upgrade includes Windows-based versions of
Microsoft Backup, Microsoft Anti-Virus, and Microsoft Undelete.
To install these programs after you have installed MS-DOS 6.0,
insert Setup Disk 1 in your floppy disk drive. At the MS-DOS
command prompt, type the following command and press ENTER
where <drive> is your floppy disk drive.
For more information on the Windows-based utilities, refer to
the "Microsoft MS-DOS 6 User's Guide."
