The lowest level bootstrap code is stored in non-volatile storage. This uses a simple protocol such as BOOTP to request and download more sophisticated boot code and eventually, the operating system. The archtypal product was the 3Station developed by Bob Metcalfe at 3Com. Another example was the Sun 3/50. Diskless workstations are ideal when many users are running the same application.
