You can use this method to start up any supported client computer from a NetInstall disk image. When you start up with the N key, the client computer starts up from the default NetInstall disk image. If multiple servers are present, the client starts up from the default image of the first server to respond.
The N key also provides a way to start up client computers that don’t have operating system software installed. For more information, see Set up diskless clients.
Start up (or restart) the client computer and hold down the N key immediately after you hear the startup tone (while the screen is still black).
Release the N key when the globe icon appears in the center of the screen.
If a login window appears, enter your name and password.
The network disk image has an icon typical of server volumes.
