Ampro Corporation COM 830 manual Win XP Watchdog Acpi Event restart configuration

Chapter 4 BIOS Setup Description

NOTE In ACPI mode it is not possible for a “Watchdog ACPI Event” handler to directly restart or shutdown the OS. For this reason the BIOS will do one of the following:

For Shutdown: An over temperature notification is executed. This causes the OS to shut down in an orderly fashion.

For Restart: An ACPI fatal error is reported to the OS.

It depends on your particular OS as to how this reported fatal error will be handled when the Restart function is selected. If you are using Windows XP there is a setting that can be enabled to ensure that the OS will perform a restart when a fatal error is detected. After a very brief blue-screen the system will restart.

You can enable this setting by going to the “System Properties” dialog box and choosing the “Advanced” tab. Once there, choose the “Settings” button for the “Startup and Recovery” section. This will open the “Startup and Recovery” dialog box. In this dialog box under “System failure” there are three check boxes that define what Windows will do when a fatal error has been detected. In order to ensure that the system restarts after a 'Watchdog ACPI Event” that is set to 'Restart', you must make sure that the check box for the selection “Automatically restart” has been checked. If this option is not selected then Windows will remain at a blue-screen after a “Watchdog ACPI Event” that has been configured for 'Restart' has been generated. Below is a Windows screen-shot showing the proper configuration.
