Rack and method thereof for simultaneously updating basic input output systems

Abstract

A rack including a rack management controller and a plurality of server nodes, is disclosed. The rack management controller receives a firmware updating file, and generates an updating message according to the firmware updating file. Each of the plurality of server nodes includes a memory and a baseboard management controller. The memory stores firmware of a basic input output system. The baseboard management controller is coupled to the rack management controller and the memory. The baseboard management controller receives the updating message to download the firmware updating file from the rack management controller and to stores it to a storage space. The baseboard management controller controls the memory to enter a recovery mode after downloading the firmware updating file, and writes the firmware updating file into the memory to update the firmware of the basic input output system.
