You can use the following configuration parameters to determine whether or not the system will boot automatically after a power cycle or system reset.
auto-boot?
boot-device
boot-file
If auto-boot? is true, then the system boots automatically (using the boot-device and boot-file values).
These parameters can also be used during manual booting to select the boot device and the program to be booted. For example, to specify auto-booting from the Ethernet server, type:
ok setenv boot-device net ok boot
Specified booting usually begins immediately.
boot-device and boot-file are specified differently with diag-switch? set to true. See the next section for more information.
