"Himem.sys fehlt", "Steuerung der A20-Leitung nicht möglich!!" - und dann nichts gewesen?
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. |

"Himem.sys fehlt", "Steuerung der A20-Leitung nicht möglich!!" - und dann nichts gewesen?
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. -- Glen Ventura, MS MVP Shell/User, A+ http://dts-l.org/goodpost.htm "Alex Wenzel" wrote in message newsp.s5ynmqp4l0h2fi@tp600e...

Himem.sys, A20 line (was: "Himem.sys fehlt" etc.)
Well, I didn't expect answers to a German message erroneously posted in
an all-English group, I'm amazed... Here are some more clarifications: The problem is already gone. It was solved by entering the BIOS once, changing *nothing* and saving on exit. Strange. But anyway, I'm interested in what exactly the problem was. BTW: Before I tried the failed Ubuntu install to the separate parition, everything worked correctly. And I later did another install of Ubuntu (from another CD, the first one turned out to be defective), whithout getting the "himem.sys" error. Some other problems, but nothing related to DOS/Windows. Now everything works and dual boots fine.

Himem.sys, A20 line (was: "Himem.sys fehlt" etc.)
On 7 Mar 2006 03:37:44 -0800, "Alex Wenzel"
put finger to keyboard and composed: Well, I didn't expect answers to a German message erroneously posted in an all-English group, I'm amazed... Here are some more clarifications: The problem is already gone. It was solved by entering the BIOS once, changing *nothing* and saving on exit. Strange. But anyway, I'm interested in what exactly the problem was. I can only imagine that some register in your motherboard chipset was disturbed in such a way as to affect himem's ability to control the A20 address line. AFAIK, the keyboard controller is somehow involved. BTW: Before I tried the failed Ubuntu install to the separate parition, everything worked correctly. And I later did another install of Ubuntu (from another CD, the first one turned out to be defective), whithout getting the "himem.sys" error. Some other problems, but nothing related to DOS/Windows.

IBM PS/2 and Compaq Prolinea computers may require a value of 2. What exactly is "himem.sys /m:1" for? The following are excerpts from the online help for himem.sys. A20 is address bit 20. If himem.sys is unable to control A20, then you will have no access to memory beyond 1MB, including the first 64K segment above the 1MB boundary (ie the HMA). ================================================== ===================== HIMEM is an extended-memory manager--a program that coordinates the use of your computer's extended memory, including the high memory area (HMA), so that no two applications or device drivers use the same memory at the same time. ================================================== ===================== /A20CONTROL:ON|OFF Specifies whether HIMEM is to take control of the A20 line even if A20 was on when HIMEM was loaded. The A20 handler gives your computer access to the HMA. If you specify /A20CONTROL:OFF, HIMEM takes control of the A20 line only if A20 was off when HIMEM was loaded. The default setting is /A20CONTROL:ON. ================================================== ===================== /MACHINE:xxxx Specifies what type of computer you are using. Usually, HIMEM can detect your computer type successfully; however, there are a few computers that HIMEM cannot detect. On such systems, HIMEM uses the default system type (IBM AT or compatible). You might need to include the /MACHINE option if your computer is a type that HIMEM cannot detect and if HIMEM does not work properly on your system by using the default system type. Currently, systems that require this option include Acer 1100, Wyse, and IBM 7552. The value for xxxx can be any of the codes or their equivalent numbers listed in the following table.

Himem.sys, A20 line (was: "Himem.sys fehlt" etc.)
Franc has already given you some extra info on the A20 line. If Memtest did not
find any RAM errors, and if the problem does not recur, I would chalk it up to a momentary glitch as Franc suggests. Was it due to the Ubuntu install problem? I don't know....I am not sure how a Linux install might affect such things. The fact that you were able to correct it the way you did points to 'glitch' more than to a permanent hardware problem. Obviously, it is something to keep an eye on, and a good excuse to make sure your backups are up to date. :-) Hope that helps..... -- Glen Ventura, MS MVP Shell/User, A+ http://dts-l.org/goodpost.htm "Alex Wenzel" wrote in message oups.com...

Franc, glee,
thanks for all your hints and suggestions. I think I'll subscribe to the 'glitch' point of view, makes me feel better :-) |
