Methods and systems for booting a computer in a distributed computing system

摘要

A field mountable controller boots by transmitting a seed letterbug to a server. The server responds with an initial operating system and program. The program reads configuration information about the controller and transmits it back to the server which responds with a particular letterbug for the controller. The controller then transmits the letterbug to a boot image server which returns a corresponding operating system image to the controller. The controller then boots using the operating system.
