Watchdog ACPI
Event
Shutdown
Restart
Select the operating system event that is initiated by the watchdog ACPI event.
These options perform a critical but orderly operating system shutdown or restart.
Note
In ACPI mode, the 'Watchdog ACPI Event' handler cannot directly restart or shutdown the OS. For this reason, the congatec BIOS
For Shutdown: Executes an over-temperature notification. With this notification, the operating system shuts down in properly.
For Restart: Reports an ACPI fatal error to the operating system.
Additionally, the conga-PA3 module does not support the watchdog NMI mode because COM Express type 6 modules do not have the
PCI_SERR# signal. Without this signal, there is no way to drive an NMI to the processor.
