I installed Knoppix 3.3 (using the Knoppix Install Option) onto the hard disk of my Toshiba Laptop. It detected all my hardware properly but I am having problems with password access . I am not asked to log on when booting up and when I want to do something which requires root access (like changing data/time) the administrative password I selected during install is not accepted.

Is there a default root password which Knoppix thinks is still current - and can I reset the user and root passwords without knowing this default password if it exists?
