How get to the prompt before login
 

I've read some threads here talking about getting into som files before they login, how do I do that?

what kind of "files" are you talking about? what do you want to achieve?

LOL, you sure can, if you tell your bootloader to tell the kernel to run /bin/bash instead of /sbin/init... I won't tell you how exactly, let you figure that one out. ;) Be warned, however, this procedure is risky!
