Embodiment Construction

[0099] The present invention provides a method and electronic equipment for updating system firmware, which are used to solve the problem that the ME firmware cannot be updated in blocks in the prior art, by brushing the part of the firmware that needs to be updated according to the attribute information in the entire ME firmware into the above determination The image file of part of the firmware is exported, so that the ME firmware can be updated in blocks, thereby ensuring the security of user data.

[0100] The technical solution in the embodiment of the present invention is to solve the problem that the ME firmware cannot be updated in blocks in the prior art, and the general idea is as follows:

[0101] Read and obtain the image file to be judged;

[0102] judging whether the image file to be judged is a first image file corresponding to the first system firmware;

[0103] When the image file to be determined is the first image file, N functional modules that need to be ...

Abstract

The invention discloses an electronic device and a method for updating pieces of system firmware. The method is applied to a basic input-output system of the electronic device. The basic input-output system comprises the first piece of system firmware and the second piece of system firmware connected with the first piece of system firmware, wherein the first piece of system firmware comprises M function modules. The method comprises the steps of reading and obtaining a mirror image document to be judged; judging whether the mirror image document to be judged is a first mirror image document corresponding to the first piece of system firmware; when the mirror image document to be judged is the first mirror image document, determining N function modules required to be updated from the M function modules on the basis of the first mirror image document; updating the N function modules. The electronic device comprises a machine shell, a circuit board and a basic input-output system chip, wherein the circuit board is arranged on the machine shell, and the basic input-output system chip is arranged on the circuit board and used for updating the first piece of system firmware in the basic input-output system.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method for updating system firmware and electronic equipment. Background technique [0002] With the development of science and technology, the application of computers is becoming more and more extensive. Major semiconductor chip manufacturers have launched more and more service management platforms to help users manage, repair, and maintain computers. For example, the AMT (Active Management Technology, Intel Active Management Technology) platform launched by Intel Corporation. For computers with AMT platform, engineers can remotely manage and detect the system when the operating system is damaged or the system fails, or actively send a warning message when the system fails, perform software and hardware inspection, remotely update BIOS, virus code and The operating system, even when the system is powered off, can be managed over the network. [0003] Currently, various fu...
