Extract bios password from EliteBook 840 G8 Bios dump, possible?

12-13-2021, 02:29 PM

Hello,

Is it possible to extract bios password from Bios dump instead of clearing the password? I have a EliteBook 840 G8 and would really need to know some way to extract the bios password and se it in clear text.

Best Regards

do you know how to use the program HxD ??? enter the bios in the program and search in "HEX-VALUE" .... 48 00 50 00 5F 00 4D 00 55 00 44 ..... and in that region you will find ... AA 55 3F .. where it replaces with AA 55 3C ... this is an example ... you have to replace everything that is written in the notepad..after you modified the bios you write it on the bios chip ....
