BIOS-Setup Password via Software

You can download the program ctbios15.zip from the german Computermagazine c't.

Ctbios shows the password and some more interesting things about your BIOS. (great tip !)

Killing the BIOS-Boot Password

If your PC doesn't start, have a look into your mainboard manual, or after opening your pc,

onto your mainboard. Many mainboards have a JUMPER or SWITCH to clear the cmos (CLEAR CMOS).

 

Attention: All hardware settings (harddisk-, bootsequence,-...settings) will be deleted !

At least, you have to re-insert them again.

 

 

 

Killing the BIOS-Setup Password

You need a DOS-Bootdisk and one of the following files:

 

File  Sourcecode I  Sourcecode II  

DEBUG.EXE  - o 70 2E

- o 71 FF

- Q  - o 70 17

- o 71 17

- Q  

QBASIC.EXE  

- 10 OUT &H70,17

- 20 OUT &H71,0  

- 10 OUT &H70,&H17

- 20 OUT &H71,&H17  

 

After re-programming you must restart your PC !

 

 

 

Repair the Flash-BIOS

If your PC doesn't start anymore ?

Use the Flash-BIOS-Recovery-Service JUMPER.de

euh en fr ca donne koi paske mo l english ,ji capte ke dalle .c est un truc pour tue son bios? le povre!

non sans rire kelle est l utilites de ton truc stp maeke.

Apprends à lire l'anglais, il y a les bips d'erreur de chacun des fabriquants de bios, comment entrer dans le bios de chaque fabriquant, comment déterminer le fabriquant de la carte mère et d'autres détailes.

Fais pas la tête âme, pas de ma faute si je n'ai trouvé le document qu'en anglais et que je n'ai pas le temps de le traduire ou de refaire la mise en page.

J' fé pas la tête

Je dis juste que je trouve ta réponse débile (Mais je dit pas que tu l' es !)

 

Sur un Forum Anglais ca en interessera + qu' ici

[Maeke]

Je répète: j'ai pas le temps de traduire (chuis au boulot).

[Y@kuz@]

ouaip , moi j'ai mon éditeur de rom bios , je m'en sert des fois pour enlever les logos constructeur au boot , c 'est laid.

sinon pour le pass perdu , préfère faire mille fois un clear cmos ou mettre un carton entre le contact et la pile bios.

 

 

google ca va trés vite pour traduire ... oki je sors Th

[Maeke]

Oki, ça va vite, mais question qualité de la traduction!

En plus, je suis pas passé par google, je suis tombé dessus par hasard (je cherchais des logos epa).

 

Compléments: comment identifier le fabricant de la carte mère (et la carte mère elle-même par la même occasion).

 

If you want to update your BIOS, you must identify your mainboard/-manufacturer. There are  

3 different ways to do so:

 

Per Software. That's the easiest way to obtain to the informations. Try this free tool ctbios.zip.  

It's from the german computer magazine c't and informs about many internal BIOS settings  

like BIOS-passwords, chipsets, mainboard-manufacturer...

Open your PC. The heaviest way to find your infos. Take a look on some imprints

on the mainboard, and sticker on the flash-eeprom.

 

BIOS-ID during boot process. Reboot your PC. You will need to record the BIOS ID string,  

which can be located at the bottom-left corner during startup. Press the "Pause"-key to  

suspend the process and copy the ID string.

 

 

 

On the example picture (above) at the bottom left corner you can see:

 

....6A69MA1AC-00   BIOS-ID number (00)

               |

               |BIOS manufacturer (A1 = ABIT)

 

O.k. it's an ABIT, but which type ? Go onto the manufacturer homepage and use the BIOS-ID-string

to find your mainboard...
