Re: edit toshiba bios image to accept any response code

Guys, I took a buiness trip for almost one year and let my personal notebook toshiba tecra R480 at home without battery. this Satarday (23/jan) when I turn it on I had a surprise, he is asking me BIOS password, but I never put it. Looking at internet I discovered how to show Serial number and challenge code.
What a need is a response code. Anyone knows how can I get it?
