Since the BMC has a USB HUB in the chip itself, and the positions of the ports connected under the USB HUB can be freely selected according to the design of the server system, the BMC can mount the system software to different USB ports under the BMC USB HUB as needed, and realize that a USB device that can be started is virtually provided for the first host by mounting the system software to the USB port of the first host, thereby providing a direct way to provide host startup for the system software.

[0065] In some embodiments, the execution subject performing the above steps can be the BMC. In the above steps, the second processing information includes but is not limited to: system software function instructions (for example, system software startup instructions, system software function execution instructions, execution state query instructions, etc.), and the system software function instructions include but are not limited to: various instructions of the system software online server, various upgrade instructions of the system software to the server system (for example, firmware, component upgrade), various deployment instructions of the system software to the server (for example, raid (Redundant Array of Independent Disks) configuration, various parameter configurations, etc.), daily maintenance data collection instructions of the system software, server one-key erasing function instructions, etc., and the BMC includes but is not limited to interacting with the system software according to the preset logic in the following ways: the system software communicates with the BMC through a network interface, the system software communicates with the BMC through a keyboard control signal; the system software obtains the second processing information from the BMC; and the system software analyzes the second processing information.
