    Possible solution: Lost password - Resetting the BIOS, or this.

    That code indicates you've got a Latitude C640 with a 595B bios, so try the solution at http://www.techadepts.com/?p=385. It's been a few years, but I have successfully used that to recover old Latitude bios passwords before.

    (Tip: Normally I wouldn't recommend downloading exes from unfamiliar sites, but if you're not into compiling the C code yourself you can scroll to the bottom of the code and there's a Windows binary you can download. This one seems to be okay but as usual in these kinds of things, caveat emptor.)
