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, also suddenly 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 much 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. It is also responsible to initiate POST which is a self-check done on the system by itself.
Part 1: How to crack BIOS password
There are some annoying scenarios where you want to change some settings in BIOS and you 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.

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 position of the Jumper 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 location of the BIOS jumper on the motherboard by checking in product documentation and reset the same.

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.

It is very easy to identify on the motherboard since it will be round, flattened, and coin-shaped. It stores the BIOS settings which include basic hardware settings, date, time, and other system information. To remove the CMOS battery, firstly the system has to be turned off, and also make sure that power cable is disconnected.
Step 2: Remove and put back the battery
Once the system is completely turned off remove the CMOS Battery. Wait for 15-20 minutes. Put back the CMOS battery and turn on the system.
Step 3: Reset password
After step 2 is done you can bypass the BIOS password and can log in to your computer successfully. Note that you can add a new password again from BIOS. If you forget the password again then continue steps 1 and 2 to reset the password.
