1.6.1 Boot the System
The most important function of OpenBoot firmware is booting 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 SelfTest
(POST). This occurs without user intervention.
If necessary, you can explicitly initiate the boot process from the OpenBoot command
interpreter. Automatic booting uses the default boot device specified in non-volatile 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, type the following command at the Forth
Monitor prompt.
