My friend asked me to reset his Dell Inspiron 1525 password-protected BIOS. At first, I thought it was just a matter of locating, removing and reinstalling CMOS battery on the motherboard and everything will be OK. It clears the BIOS settings including the password. I downloaded the disassembly guide, open-case surgery for an hour until I managed to put everything back. And when I turned the power back on, I ended up scratching my head. The password was still set, asking me for Admin Password again! So I did a research and it s very clear that Dell has done upgrades, they isolated BIOS password in a small flash chip providing more level of security for the data on the system and contacting Dell is not an option especially from our country because it will take ages before you get a response from them until I ran across this code from a Russian hacker hpgl managed to crack the algorithm that Dell is using to generate these backdoor password. You can see the code here. Copy and paste the code. Run the program. If you are using Windows you can download Windows Binary here It s a good practice to scan the file you downloaded.
