Abstract

An Information Handling System (IHS) includes multiple hardware devices, and a baseboard Management Controller (BMC) in communication with the plurality of hardware devices. The BMC includes a first processor for executing a custom BMC firmware stack, and transmitting a watchdog message at an ongoing basis. The BMC also includes a second processor for receiving the watchdog message. When the watchdog message is received within a specified elapsed period of time, allow continued operation of the custom BMC firmware stack, and when not received within the specified elapsed period of time, place the BMC in a failsafe mode of operation.
