Do you have any of these versions of Norton SystemWorks installed: Norton
SystemWorks 1.0, Norton SystemWorks 2.0, Norton SystemWorks 2000, Norton SystemWorks
2001, Norton SystemWorks 2002?

If so, follow these instructions:

After installing Norton SystemWorks and restarting the computer, you see one or both
of the following error messages:
- HIMEM.SYS is missing. Make sure that the file is in your Windows directory.
- Unable to control A20 line. XMS driver is not installed.

To solve the problem:

Restart the computer in Safe Mode Command Prompt Only:
- Click Start, and then click Shut Down. Click Restart, and then click OK.
- As the computer restarts, press and hold down the Ctrl key until the Windows 98
Startup
Menu appears, OR repeatedly tap F8 just prior to the Windows splash screen.
- Select Safe Mode Command Prompt Only, and then press Enter. Windows will display a
DOS prompt.

NOTE: In Safe Mode, Windows uses default settings: VGA monitor, no network,
Microsoft mouse driver, and the minimum device drivers required to start Windows.
You will not have access to CDROM drives, printers, or other devices.
Type: edit autoexec.bat to open the Autoexec.bat file in the DOS Edit program.
Type: set dos16m=2 as the very first line in the file.
Press Alt+F to open the file menu, and then press S to save the file.
Press Alt+F to open the file menu, and then press X to exit the editor.

Restart the computer to see whether the problem is solved. If not, then continue
with these steps.

Restart the computer in Safe mode command prompt only.
Type EDIT AUTOEXEC.BAT to open the AUTOEXEC.BAT file in the DOS Edit program.
Locate the following line:

C:\PROGRA~1\NORTON~1\NAVDX.EXE /STARTUP

Add REM to the above line so that it reads as the following:

REM C:\PROGRA~1\NORTON~1\NAVDX.EXE /STARTUP

Type the following keys individually to save and exit from the file: Alt, F, X, Y.
Hold down the power button for 10-15 seconds until the computer is shut off.
Restart the computer and the error message should not be displayed.

If you still get an error message, please refer to the next solution.

Restart the computer in Safe Mode Command Prompt Only.
Type edit config.sys to open the Config.sys file in the DOS Edit program.
The Config.sys file may include the following line. You may need to append a space
and /M:1 only or add the entire line.

device=c:\windows\himem.sys /m:1

Press Alt+F to open the file menu, and then press S to save the file.
Press Alt+F to open the file menu, and then press X to exit the editor.

Restart the computer.

NOTE:
If Windows is installed to a different folder, then substitute the appropriate
folder name.
The value for the /M: line can range from 1 to 17. The value of 1 works for most
computers. IBM PS/2 and Compaq Prolinea computers may require a value of 2.

Hi,
mehr aus Neugier als aus Betroffenheit (Problem hat sich schon gelöst):
Nach einer gescheiterten Ubuntu Linux-Installation kam beim nächsten
Booten in Windows 98SE plötzlich die Fehlermeldung "Himem.sys fehlt" und
Booten blieb stecken; beim Starten in reines DOS kam: "FEHLER: Steuerung
der A20-Leitung nicht möglich! XMS Treiber nicht installiert."
Nach einem Besuch im BIOS (*ohne* irgendwas einzustellen) war plötzlich
alles wieder heile.
Auch Memtest zeigt keine Fehler im RAM. Ein früher Installationsversuch
von Ubuntu war auch gescheitert, hatte aber *nicht* diese Folgen auf
Windows.
Jetzt frage ich mich: Was war das?
Kann mich da jemand aufklären?
Ach ja: Es geht um ein Lifebook S4542 mit (ziemlich armseligem)
Phoenix-BIOS.
