Reset Scenarios
Two OpenBoot configuration variables, diag-switch? and diag-trigger control
whether the system executes firmware diagnostics in response to system reset
events.
POST is enabled as the default for power-on-reset and error-reset events.
When the diag-switch? variable is set to true, diagnostics are executed using user-
defined settings. If the diag-switch? variable is set to false, diagnostics are
executed depending on the diag-trigger variable setting.
In addition, ASR is enabled by default because diag-trigger is set to power-on-
reset and error-reset. This default setting remains when the diag-switch?
variable is set to false. auto-boot? and auto-boot-on-error? are set to true by
default.
