ROM BIOS or commonly known as BIOS, is an integral part of a computer. Whenever we turn on the computer, initially, it shows the memory capacity. SuddenlyThe long dark broken railroad. , the light of the NUM lock glows, and there is a beep sound at the end, after which we see the familiar Windows Logo. For a computer geek, this is normal behavior that a computer exhibits after it is turned on. However, the same cannot be said about others who are not familiar with computer hardware and might be using it to accomplish the daily tasks. They might keep on wondering what exactly happens when the computer is turned on. Here come the role and importance of the BIOS. It is a chip located on the system board or motherboard of a computer. It holds all the information about the hardware of the computer. Suppose you have added a new hard drive to your computer to enhance the space, and that hard drive is not getting detected in BIOS.

Will you be able to use that drive once you login to Windows? The answer is No; BIOS has to detect the hard drive first since it holds all the information related to hardware settings, and then it will be detected by the operating system.BIOS hold all the information related to hardware settings, system date, and time.

Part 1: How to crack BIOS password

There are some annoying scenarios where you want to change some sites, settings and find that it is not taking the password. You might get a screen like this.

This also might be a scenario where you have bought the computer for someone else, and the seller didn’t share the BIOS password. Also possible that someone else uses the same computer and has set a different password in BIOS. We keep on trying with our best-guessed passwords. But, after certain tries also it didn’t work, then do what? If I cannot enter BIOS, that means I don’ be able to make any changes in settings.

In that case, we have to break the BIOS password. There are different ways to crack the BIOS password. Some steps are given below :

Step 1 The first option will be to change the Password Jumper Settings on the BIOS. There is a specific jumper on the motherboard, which is meant for this. However, it is advisable to read the product manual first before trying this step because the Jumper position will differ from one motherboard to another.

Step 2 To perform this, one has to turn off the computer, make sure the power cable is out of the wall outlet. Unscrew the screws located on the Side Panel of the CPU.

Step 3 Once you do that, identify the BIOSjumper's locations on the motherboard by checking in product documentation and reset it.

The jumper might be labeled as CLEARCMOS or JCMOS1. However, the best will be to always refer to the product documentation.

Step 4 Once this is done, restart the computer and check whether the password is cleared or not. Now once the password is cleared, turn off the computer once again, and put back the jumper to its original position.

If the first method doesn’t work, you might try the backdoor entry. In the case of desktop, this has to be accomplished by checking the CMOS jumper.

For laptop users :

The process will be entirely different for laptop users since they have to use a backdoor password entry option. Enter the wrong password thrice on the screen, which will show an error like this.

Make a note of the code which is displayed. And then, find a BIOS password cracker tool like this site: Enter the displayed code, and then the password will be generated in a few minutes.
