Click on verify to check the integrity.Open the BIOS dump file you want to write.Step 3: Now, To write the data into the BIOS chip: All the Hex field will get filled with the data of BIOS. After that, click on Read and wait for some minutes.All the details like Type, Manu, Name will automatically be fetched. To take the dump of a BIOS-Chip, we require two devices: We just need to reprogram the BIOS chip from that dump (the service was paid $15 ). The 2nd option was good because all they(forum guy) require was the dump of BIOS with the Administrator password, and they will just remove the password from it and send the dump back. I went for the 2nd option because the international delivery was not available due to COVID-19, and it was costly too because I had to spend more on the technician who will replace the BIOS chip(also involves desoldering and all). (if the wrong dump is used then it could fry the motherboard) Reprogram the current BIOS with the correct dump of BIOS with no password.(I found one on eBay for just $24 from Taiwan) Replace the BIOS chip on the motherboard with a pre-programmed BIOS Chip.I was just trying to access the BIOS memory through windows, but I failed (I am a total beginner in reverse engineering).Īfter desperately searching on the internet, I found some forums that solve this kind of problem. I came across some WMI Namespaces of windows, which was working as some sort of functions, which makes the input as current password and New password.
I disassembled the BCU.exe file and tried to understand the code and It took me some days to get the idea of its working.
So, I thought to look into it to see if I can do something with it.
It’s a command-line tool that can change the BIOS passwords and other configurations. Reverse Engineering: There’s software provided by HP for system administrators to configure the BIOS just by executing a script in the system, i.e., HP BIOS Configuration Utility(BCU). I am not spending that much amount of money.ģ. So, I called the service center, and they told me that the company changed its policy in 2019, and they can only resolve this issue by replacing the motherboard now(the price of which is around $450+). Service Center: Now, from some company support forums, I got to know that the company provides the smc.bin file to reset the password of BIOS. (i) System Disabled Code & (ii) HP SpareKey Recovery(Example of error)Ģ.
