Re: Dell Latitude 5400 Bios password

Hello,
I found a solution to clear password from BIOS bin file (using "Hex Editor Neo"):
1- Select the range 00045000 to 00048fff
2- Select "Edit" then "Fill"
3- Put "ÿ" in "Pattern" zone.
4- Choose "Fill selection" then clic on "Fill" button.
5- Save the new file.
Enjoy!!
NB : Always make copy of backup then work....

thank you

I apologize for re-posting. But in post 401 there is no required bios file 8mb. And I can't edit the post.

OK upload the 8MB dump, I'll edit the post #401 for you.
And next time attach the files in а standard way to the post below the text so the size of the attached file to be visible:
