Stop-a sequence on a Sun keyboard.

3. Set the diag-level configuration variable.
Two different levels are available for testing. To achieve the maximum coverage set
diag-level to max. See “How to Set the Diagnostics Level” on page 186.

The OpenBoot Diagnostics menu appears. This menu displays a numbered list of all
available tests.

For more information about what each available command does, see “About
OpenBoot Diagnostics Tests” on page 168 or use the help command.
Note – Use of the OpenBoot PROM configuration variable test-args can affect
the behavior of OpenBoot Diagnostics. The test-args variable is empty by default.
Use the help command for more information on test-args.
If any problems are found by the test, OpenBoot Diagnostics displays an error report
on the console. The first line of the error report describes the possible problem. The
optional summary line displays the associated memory address and values.
