OpenBoot 3.x Command Reference Manual

Selecting Boot Options

You can use the following configuration variable to determine whether or not the system will boot automatically after a power cycle or system reset.

If auto-boot? is true and if OpenBoot is not in diagnostic mode, the system boots automatically after a power-cycle or system reset using the boot-device and boot-file values.

These variables can also be used during manual booting to select the boot device and the program to be booted. For example, to specify default booting from the network server, type:

ok setenv boot-device net 

Changes to boot-file and boot-device take effect the next time that boot is executed.
