The invention discloses a resource management method, a resource management device, electronic equipment and a storage medium, and relates to the technical field of computers. The resource management method comprises the steps that the preset resource information of the bus equipment of the current server is written into the storage unit when the current server is in the cold standby state, and the risk of tampering the preset resource information in the server power-on process is reduced. When the server is powered on, the basic input and output system can obtain preset resource information through the programmable controller mounted on the storage unit and compare the preset resource information with initialized data formed by the preset resource information, so that whether the power-on process is reliably configured or not can be verified, and reliable pre-storage and reliable obtaining of the resource information are achieved. The technical problems that the transmission of the resource allocation strategy is unreliable and whether the server is reliably powered on or not is difficult to verify are solved, and the technical effects of improving the transmission reliability of the preset resource information and improving the startup and operation reliability of the server are achieved.
