1.9.1 Boot the System
The most important function of OpenBoot firmware is the booting of the
system. Booting is the process of loading and executing a stand-alone
program such as the operating system. After it is powered on, the system
usually boots automatically after it has passed the power-on self test
(POST). This occurs without user intervention.
If necessary, you can explicitly initiate the boot process from the Open-
Boot command interpreter. Automatic booting uses the default boot de-
vice specified in nonvolatile RAM (NVRAM); user initiated booting uses
either the default boot device or one specified by the user.
To boot the system from the default boot device, enter the following com-
