The easiest way to root any Unix-like machine is to start it in single  
user mode (add '1' or 'single' to the kernel boot parameters). That  
way you are logged in as root without being prompted for a password.  
Once logged in you can run 'passwd' and set a new root password. No  
boot disc needed. :o) (If your boot loader is also password protected  
or if runlevel 1 is protected and you don't have the password things  
get more difficult.)
