Configuration method and device for pre-starting execution environment function and server

The invention discloses a configuration method and device for a pre-boot execution environment function, a server and a computer readable storage medium, and relates to the technical field of servers, the method comprises the following steps: the server obtains interface information of a basic input and output system in a starting process of the basic input and output system; judging whether a PXE (pre-boot execution environment) function is supported or not according to the basic input and output system interface information; if yes, according to the target network card network port, PXE functions corresponding to network ports in network card equipment connected with the server are configured, so that after configuration is completed, the target network card network port is provided with the PXE function, and the non-target network card network port is not provided with the PXE function; according to the method and the device, the PXE function is started for only one target network card network port, and th
