Red hat linux problems...?

I have installed linux 9 many times now! Each time I have selected my graphics card and default monitor and numerous other combinations all of which result in my monitor going crazy! This time I chose the ‘X’ option which allows you to configure your graphics card later, when rebooted I chose linux 9 and I was asked for a login and password. In the installation you set your password but what is my username?

Any help would be appreciated.
