CIM_WatchDog

The CIM_WatchDog class described in Table below represents a timer that is implemented in system hardware. The watchdog

feature allows the hardware to monitor the state of the operating system, BIOS, or a software component installed on the system. If

the monitored component fails to rearm the timer before its expiration, the hardware assumes that the system is in a critical state

and could reset the system. This feature can also be used as an application watchdog timer for a mission-critical application. In this

case, the application would assume responsibility for rearming the timer before expiration.
