How to Break BIOS Password

The BIOS password is a security feature in the BIOS of the computer. Once enabled, the user cannot access the system without entering the BIOS password. This password secures the basic input-output of the system. The system boots only after receiving the password, so there is no way to enter without knowing it.

Once you forget the BIOS password, you are completely blocked out of your system. No password reminders or alternate questions. Thankfully, there is a very simple way to reset the BIOS password.

Hacking the BIOS

To reset the password, the BIOS has to be put into the configure mode. This is done by replacing a jumper on the board. (A jumper is nothing but a piece of metal that shorts two contacts.) For the Intel 845 gvsr motherboard, the jumper is near the motherboard battery. (See image). Refer to your motherboard manual to find the jumper.

Just replace the jumper into the configure mode, and switch ON the system. You will see something similar to the following screen.

Select โ€˜Clear ALL Passwordsโ€™ and both Supervisor password and System Password will be reset. You can install a new password in the Security tab. Press F10 to save and exit. Turn OFF the system, replace the jumper to the initial position and turn ON the system.

All demonstrations are based on the Intel 845 gvsr motherboard. Most motherboards will have a similar jumper. Refer to the motherboard manual.

Divi WordPress Theme - My Review

Divi WordPress Theme
Divi is a WordPress theme that web designers do not want you to know. It comes with a drag-and-drop theme builder. You can build beautiful looking unique websites without touching a line of code. Just choose from one of the many pre-made layouts, or pick elements and arrange them any way you like.

Divi is every WordPress developer's wet dream. Surprise your clients with neat responsive websites and have fun building them.

Divi comes from Elegant Themes. If you enjoy building websites, you *need* an Elegant Themes membership. 87 beautiful themes and 5 plugins for the cost of less than a candy-bar each!

Note: I am an avid user of Divi myself and this is a honest review. I wouldn't recommend something that I do not personally find amazing.

    For me, I just reset the password by just removing the cmos battery for around 10 seconds, then place it back. Doing this should let you manually set the system time and date from the BIOS menu and set your chosen password again (if you want) before you let it run again.

    • Arun says:

      Wow! Never thought of removing the battery, thats pretty simple and you dont have to tangle with the jumpers on the mother board. thanks for sharing.

      BTW, just cheked out your site, The OBP logo is cool..


      • frenchy says:

        Thanks for the compliment about the logo. I honestly think it looks odd and I was about to remove it. But now i changed my mind. BTW, congratulations for being the top so far on Ajith’s contest. And oh, I love the template that you used for this blog especially the blending of different gray-black tones plus the little touch of red on the links. Looks good.

        • Arun says:

          Hey, if you are not satisfied with your logo, change it soon. Personal satisfaction is very important. ๐Ÿ™‚

          BTW, I have just uploaded some logo designs that you might consider. See this collection.

          Thanks for the mention of the DS contest..

    Quite useful advice. I’ve used this type of procedure before when troubleshooting computers but had a BIOS password in place that no one remembered what it was.
