Parameter

Values

Description

 

 

 

setkeyswitch*

normal

The system can power on and run POST (based

 

 

on the other parameter settings). For details see

 

 

FIGURE 2-16. This parameter overrides all other

 

 

commands.

 

diag

The system runs POST based on predetermined

 

 

settings.

 

stby

The system cannot power on.

 

locked

The system can power on and run POST, but no

 

 

flash updates can be made.

diag_mode

off

POST does not run.

 

normal

Runs POST according to diag_level value.

 

service

Runs POST with preset values for diag_level

 

 

and diag_verbosity.

diag_level

min

If diag_mode = normal, runs minimum set of

 

 

tests.

 

max

If diag_mode = normal, runs all the minimum

 

 

tests plus extensive CPU and memory tests.

diag_trigger

none

Does not run POST on reset.

 

user_reset

Runs POST upon user-initiated resets.

 

power_on_reset

Only runs POST for the first power on. This is the

 

 

default.

 

error_reset

Runs POST if fatal errors are detected.

 

all_reset

Runs POST after any reset.

diag_verbosity

none

No POST output is displayed.

 

min

POST output displays functional tests with a

 

 

banner and pinwheel.

 

normal

POST output displays all test and informational

 

 

messages.

 

max
