How to Autologin as a root(Superuser)

[harshavardhanreddy mandeepala <hvreddy1110 gmail com>]

Hi,
I am using Linux Fedora Core 3.
I want to Automatically login as a root(Superuser)when the system is
swiched on (Boots up).That is i don't want to enter any passwords, it
should automatically enter into  the system.
I can do it for non root user by changing in 
               Application->systemsettings->loginscreen.
for  superuser it is not allowing.
so if u have a  solution plz send it to           hvreddy1110 gmail com

thanks  in advance.

Regards
