Server starting control method and device and server

The embodiment of the invention provides a starting control method and device of a server and the server, and the method comprises the steps that in the starting process of the server, N first signals of a mainboard are determined, and N is a natural number larger than 1; under the condition that N is greater than or equal to a first preset threshold value, determining multiple pieces of mainboard configuration information by utilizing N first signals; target mainboard configuration information matched with a target customer demand is determined from the multiple pieces of mainboard configuration information, and the target customer demand is used for representing the configuration demand of a target customer for a mainboard; and loading the BIOS parameters based on the target mainboard configuration information so as to configure the operation of the server according to the BIOS parameters. Through the server configuration method and device, the problems of high cost and poor availability of the server in se
