After POST passes successfully, there is a display output to the console.
If a TTY terminal is available, you may boot up in DIAG mode and make
use of the OpenBoot PROM. The system will attempt to boot from a
selected device specified in the boot path.
You will see status messages on the display. At completion
of power-up the login prompt is displayed.
All system board LED patterns begin cycling, except boards
without SuperSPARC modules, where LEDs stay on.
Continue to monitor the system start-up and note the start of
system services. If any required system services do not start,
it may be necessary to recover the missing or corrupted
service from the installation or backup tape.
If this is not the problem, go to branch D.
