I have a toshiba satellite c655d-s5518. I boght this for a proyect (i knew is an old laptop), and i need acces to the full bios, not the capped version. I've been trying everything, and so far the only solution is to make a backup of the bios, edit it, save, and reflash. The fact is i dont have the knowledge to do that. Is there a combination of keys to acces that options? If not, i will go to the nuke solution and learn how to do that.
