OpenBoot PROM Enhancements for
Diagnostic Operation
This section describes the diagnostic operation enhancements provided by OpenBoot
PROM Version 4.15 and later and presents information about how to use the
resulting new operational features. Note that the behavior of certain operational
features on your system might differ from the behavior described in this section.

What's New in Diagnostic Operation

The following features are the diagnostic operation enhancements:
New and redefined configuration variables simplify diagnostic controls and allow
you to customize a "normal mode" of diagnostic operation for your environment.

events. See
Service mode establishes a Sun prescribed methodology for isolating and
diagnosing problems. See
The post command executes the power-on self-test (POST) and provides options
that enable you to specify the level of diagnostic testing and verbosity of
diagnostic output. See
