Embodiment Construction

[0028] In the present invention, the multiple clients are connected to the server through the network. Each of these clients and servers includes a network card. A method for remotely updating a firmware system based on a general extensible firmware interface proposed by the present invention will be described in detail below in conjunction with the accompanying drawings:

[0029] The present invention is a method for remotely updating a firmware system based on a general extensible firmware interface, such as figure 1 As shown in FIG. 1 , it is a client architecture diagram for realizing UEFI BIOS remote upgrade in the present invention. The client computer starts up and enters the UEFI firmware system, establishes a network connection, logs in to the server to query, accepts the upgrade file, upgrades the firmware, and reports related upgrade results to the server. Specific steps are as follows:

[0030] Step (1): Create a connection: When creating a connection, you need ...

Abstract

The invention provides firmware system long-distance updating methods based on a unified extensible firmware interface. A client server structure is adopted by the methods. The client server structure comprises a server and a client machine. A network protocol stack is achieved on UEFIBIOS by the client server structure, and data transmission is carried out by the client machine through a network and the server. The number of the long-distance updating methods is two. One method is that a client machine UEFIBIOS long-distance updating method is started by the server, and the other method is that UEFIBIOS long-distance updating method is started by the client machine. According to the long-distance updating methods, no assistance of mobile devices is needed, long-distance updating of UEFIBIOS is achieved through the network by the server, labor power and cost is reduced, and good control of the upgrading of UEFIBIOS is achieved.

Description

technical field [0001] The invention belongs to the technical fields of computer software engineering and network communication, and specifically refers to a method for remotely updating firmware systems based on Universal Extensible Firmware Interface (UEFI). Background technique [0002] As a bridge between the operating system and the hardware system, the traditional basic input and output system BIOS has made important contributions to the development of computers. BIOS belongs to the underlying software in the computer and is a bridge between hardware and software programs. It is responsible for solving the immediate needs of the hardware and specifically implementing the operating requirements of the software for the hardware. It is responsible for the initialization work before the execution of the operating system, including checking the system configuration and connecting various hardware in the computer and booting the operating system, etc., and is responsible for...
