where is the installation script located?

Hi all,

I have an intriguing question....

Consider these options..(obtained the first installations of solaris)

1.solaris installation -console mode
2.single user login
3.update drivers

I wanted to know which script handles this and where it is located?
Does anyone know the absolute path of the script that generates this output on the screen?

PS:pardon me for not writing all the options..
I am recollecting this from memory :cool:

Thanks
