The ROM BIOS, commonly known as the BIOS, forms an integral part of every computer. When you turn on the computer, it first shows the memory capacity, then suddenly the NUM lock light comes on, finally a beep can be heard. You will then see the familiar Windows logo. For a computer geek, this behavior of a computer after power on is quite normal. However, the same cannot be said for people who are not familiar with computer hardware, but still use it for daily tasks. These users might wonder what exactly happens when the computer is turned on. This is where the importance of BIOS comes into play. This is a chip that is located on the motherboard or the computer. the motherboard of a computer is located. It contains all information about the hardware of the computer. Suppose you have installed a new hard drive in your computer to expand the storage space, but this hard drive is not recognized by BIOS.
Can you use the drive after you log in to Windows? The answer is: No, the BIOS must first recognize the hard disk, because contains all the information about the hardware settings. Only then the operating system can recognize it. The BIOS contains all the information about hardware settings, system date and time. It is also responsible for POST initialization, a self-check performed by the system itself.
Part 1: How to crack the BIOS password
There are a few annoying scenarios, such as when you want to change settings in the BIOS, but then find that the password is not applied. You might see a screen like the following.
Maybe you bought the computer from someone and the seller didn’t tell you the BIOS password. Someone else may be using your computer and setting a new password in the BIOS. You try a few times with a few passwords you just remembered. But after a few attempts works you do not get further, what now? If you can’t access the BIOS, you can’t change the settings.
In this case you need to crack the BIOS password, there are several ways to do this. The necessary steps are listed below:
Step 1 The first option is to change the password jumper settings of the BIOS. There is a special jumper on the motherboard, which is designed exactly for this purpose. However, you should first read the product manual before performing this step, as the jumper position may differ between different motherboards.
Step 2 The computer must be switched off for this. Make sure that the power cord is not connected to the power outlet. Remove the screws from the side panel of the computer.
Step 3 Once you have done this, determine the location of the BIOS jumper on the motherboard by looking at the product documentation. Reset the jumper now.
The jumper may be marked as CLEARCMOS or JCMOS1. However, also pay attention to your product documentation.
Step 4 Restart the computer and check whether the password has been deleted or not. Once the password is cleared, turn off the computer again and put the jumper back to its original position.
If the first method is unsuccessful, you can try using a backdoor. If you are using a desktop PC, this is possible with the help of the CMOS jumper.
For laptop users:
For laptop users, the way looks completely different. Here you have to enter the password via a backdoor, so to speak. Enter the wrong password three times on the screen. You will see an error like the following.
Write down the displayed code. Then get you a BIOS password cracker tool, z.B. from this website: http://bios-pw.org/ Enter the displayed code. Now the password is generated within a few minutes.
Part 2: How to bypass the BIOS password
Another situation similar to the scenarios described above can be solved by bypassing the BIOS password. The methods that can be used here are similar to those of the described scenarios. In addition, you can also use one of these two methods:
method: Overloading the keyboard buffer
This method is especially usable on some older system boards, and it may not be usable on newer systems. It consists of booting the system without a mouse or keyboard. With certain BIOS architectures, however, the ESC key must be pressed in rapid succession.
Part 3: How to reset the BIOS password
If you have tried to crack the BIOS password and got stuck, you may be able to reset the BIOS password easily.
Method 1:Remove the CMOS battery
Step 1: Find the CMOS battery.
The CMOS battery has a flat, round shape. The CMOS is an integral part of the BIOS on the system board. Every motherboard has a CMOS battery. It is very easy to spot on the motherboard: It is round, flat and shaped like a coin. It saves the BIOS settings. This includes basic hardware settings, date, time and other system information. To remove the CMOS battery, the system must first be turned off. You should also make sure that the power cord is disconnected.
Step 2: Remove and reinsert the battery
Once the system is completely shut down, remove the CMOS battery. Wait 15-20 minutes. Put the CMOS battery back in and power up the system.
Step 3: Reset password
After step 2, you can now bypass the BIOS password and successfully log in to your computer. Note that you can set a new password in the BIOS. If you forget the password again, continue with steps 1 and 2 to reset the password.

Method 2: Run a command from the MS-DOS command prompt
This method works only if you have access to the installed operating system. Once logged into your desktop, run the MS-DOS program and then the following commands in the correct order as seen here:
debug, o 70 2E, o 71 FF, quit
This command resets the BIOS settings, which includes the BIOS password. This process is performed using MS-DOS debug tool.
Method 3: Use third-party software
Nowadays, there are many third-party software products that can help them reset the BIOS password. However, this requires access to the operating system. Some of the most popular BIOS password cracking software are CmosPwd or Kioskea
Method 4: Use the BIOS password backdoor
The BIOS password backdoor consists of a group of passwords that are master passwords provided by the BIOS manufacturer. These passwords are generic and manufacturer specific. In other words, each vendor has a set of master passwords that are independent of the password set by the particular user. These passwords are not difficult to obtain and can easily be found on the vendor’s website.
