Substrate controller interface processing method and application equipment thereof

The embodiment of the invention provides a substrate controller interface processing method and application equipment thereof, and relates to the technical field of computer systems. The substrate controller interface processing method comprises the steps of obtaining an initial configuration file in response to a starting instruction; configuring the initial configuration file, and executing a default mode; in the default mode, receiving a heartbeat trigger signal of the central processing unit through the management interface; the heartbeat trigger signal carries configuration information; and configuring and managing the small switch chip according to the configuration information. Normal starting during default work is controlled through the substrate, configuration information of the central processing unit is received, and normal work can be achieved under the condition that adaptation is not conducted on the central processing unit side. And demand configuration can be carried out based on heartbeat co
