I have a Sony laptop where the hard drive went bad. It has a BIOS password on it. I replaced the hard drive and went into the BIOS to change the device boot priority. Now my BIOS password won't work, and after three failed attempts it gives me a 16-digit hash and asks for a one-time password. There's obviously some way to generate a one-time password based on this hash, but I've looked everywhere and it looks like there are people out there who know how to do it, but none of them tell you exactly how. I called Sony support and they told me I had to send the laptop in to get the password removed, but I really don't have time for that. How can I generate a one-time password and gain access to my machine again?
