Bios a zero

utilser DEBUG
c:\> Debug
selon le type de votre Bios
en général :
c:\>debug
- o 70 2e
-o 71 ff
-Q

Ou faire un clear CMOS, via un cavalier sur ta carte mere .

Bonsoir Azs
Si tu expliquais un peu ton problème on pourrait mieux t'aider.
Autrement dans ton setup tu peux trouver en général une option de recharger le bios par défaut. Ne flashe pas ton bios sans savoir, tu pourrais etre obligé de changer la CM .

Claude

merci a tous

es ce que je peux avoir une simple solution 'cad sans ouvrir le boitier'.
et merci encors

salut,
essaie d'appuyer sur f9 au démarrage de l'ordi, il me semble que ca remet le bios dans ses relages d'usine...
je suis pas sur, si je me plante dites le moi!

merci atous
mais ca pas marche ms Asky

ah bon...désolé!

Bonsoir azs, bonsoir à tous,

Je reprends la méthode d'amimi !

Je reproduis ici le contenu de la page Web http://www.techtips4u.com/kb/sw/SW00025.htm

ATTENTION ! si manipuler la registry est dangereux, lancer un programme Assembleur peut l'être encore plus... en d'autres mots, je te laisse examiner le site source pour juger s'il est de confiance (il y a longtemps que je ne programme plus en assembleur) :

How do I clear CMOS / NVRAM using the debug command?
***WARNING - RUNNING ANY DEBUG SCRIPT ON YOUR SYSTEM DOES HAVE THE POTENTIAL TO DELETE ALL FILES ON YOUR SYSTEM AND / OR OTHER PROBLEMS. ***
This script has been tested both in dos and in windows.

Here is the script:

Boot to a Windows boot disk and use the following script.
If debug can't be found on the Windows boot disk you may have to extract it. The computer will generate the text in red and you will type the text in white, where it says (ENTER) just hit the Enter key don't type the word. After the computer restarts you will receive a CMOS checksum error and will have to reset your time , date and other settings in your BIOS .
(la seule chose en rouge est le - devant le A)

debug (ENTER)

- A <ENTER>
MOV AX,0 <ENTER>
MOV AX,CX <ENTER>
OUT 70,AL <ENTER>
MOV AX,0 <ENTER>
OUT 71,AL <ENTER>
INC CX <ENTER>
CMP CX,100 <ENTER>
JB 103 <ENTER>
INT 20 <ENTER>
<ENTER> Note: Nothing is typed on this line
G <ENTER> By pressing G this will execute the above script, ensure you have read and agree to the above warning.
Q <ENTER>

Rebonsoir,

Tiens, le script exact fourni par amimi :

Même commentaires que dans mon précédent post ! je te reproduis çà sans rien y comprendre !

Okay i was just fidgetting with DEBUG and i found out a new way to clear CMOS without opening the computer.
do this:

DEBUG
-O 70 2e HIT ENTER
-O 70 FF HIT ENTER
-Q

NOW RESTART YOUR COMPUTER...
IT WORKS ON MOST OF 'EM...IF IT DOESNT,try finding your own on astalavista.box.sk
bye!

Rebonsoir à tous,

Voici mon troisuème et dernier post sur le sujet parce que j'ai l'impression que là, çà ressemble à du crack !

Clear CMOS RAM
The first method to clear the CMOS RAM is to remove the battery on the mainboard. The battery should be removed for some 30 to 40 minutes. In the worst case you will have to desolder the battery.

If the battery is a NiCad type battery, there is no need to remove the battery. Instead, you can connect a 39 Ohm resister in parallel over the battery. Leave the resistor connected for about half an hour. Do not use this method on Lithium batteries, because these are non-rechargeable, and have to be removed from the mainboard leaving the charge intact.

The third method is to use the CMOS Selector, a 2- or 3-pin jumper on the mainboard. Consult your mainboard manual on the correct jumpersetting to clear the CMOS. If your system is provided with a MR BIOS, the CMOS Selector is not needed and the Mono/Color Selector on the mainboard can be used for this purpose. The Mono setting of the jumper is used as a master-override.

The above methods should be used when you have no access to the system. If you still have access to the system but can't access BIOS Setup, you can use software to clear the CMOS, such as:

lost.com
killcmos.zip [9 kB],
also available k-cmos32.zip a Win95/NT shell for the DOS version [39 kB],
and k-cmos32i.zip an installable Win95/NT version [1031 kB]
loesch.zip from C'T Magazin
However, you don't have to clear all of CMOS RAM. You can use DEBUG to clear a byte in CMOS RAM. In the following example, the byte at offset 2Eh in CMOS RAM is cleared:
debug[Enter]
-o 70,2E[Enter]
-o 71,0[Enter]
-q[Enter]

Although you can use DEBUG to clear a random byte in CMOS RAM, you should check out the CMOS RAM contents to see if that byte isn't already cleared. You can do this with the program cmos.exe. Also, you should use one of the bytes, for which a checksum is calculated and stored in CMOS RAM, e.i. one of the bytes from 10h thru 3Fh. So, your choice of a byte isn't completely random! Reboot the system and BIOS will find that the calculated checksum doesn't match the stored checksum and you will be forced into Setup.

i have an laptop and i forget that password for my computer , how can do for this , i wann to to open my computer because i dont know if there is an influence for the computer or not?????????

Sorry for the English, but my French is horrible, and I want to be understood. The problem I am having is with an MSI k9v board (of which we have built 12 with 5 of them having the same issue) During the boot sequence, the BIOS will not post, it wont load a splash screen, and no video will be displayed. The real strange part is if you hit the reset button a few times (with a slight pause to listen for the BIOS Post beep) eventually after about 6 tries, the board will post. Part two of the issue is once you get the board to post the CMOS checksum will be corrupt and it will load default values. I have never experienced an issue like this before and I'm starting to think that the boards are bad. If any of you can help with this it would be much appreciated. Thanks and again sorry about my English, but if you saw my attempt at French you would understand.
