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.
