I'm attempting to fix Grandma's machine - we aren't sure what has happened but the only password it has ever had for her user no longer works. In addition, when booting, we cannot get any other option for the User; previously there was a Guest Account, for instance. Of course, we do not have a password reset disc. I've been into the Setup (F2) and attempted to set the Supervisory and User passwords there, but that just added another layer of security - it hasn't resolved our problem. Short of completely re-installing the operating system and drivers (we have the original system discs) is there ANYTHING we can do to override or reset the password?
