Abstract

The invention discloses a BIOS updating method and device, equipment and a medium, and the method comprises the steps: obtaining a target updating file from a target storage unit, wherein the target updating file comprise a target BIOS mirror image file and a first BIOS digital signature of the target BIOS mirror image file; performing matching signature verification on the first BIOS digital signature by utilizing a second digital signature in an upgrading tool of a BIOS configuration interface, wherein the second digital signature is a digital signature of the target BIOS mirror image file;and if the signature verification is passed, updating the current BIOS to be updated by utilizing the target BIOS mirror image file. Thus, the second digital signature in the upgrading tool of the BIOS configuration interface is used for verifying the signature of the obtained target BIOS mirror image file, the safety and uniqueness of the obtained target BIOS mirror image file are guaranteed, other mirror image files can be prevented from being swiped in the BIOS updating process, and therefore the safety of BIOS updating is guaranteed.

Description

technical field [0001] The present application relates to the technical field of servers, and in particular, to a BIOS update method, apparatus, device and medium. Background technique [0002] At present, there are two main ways to upgrade the firmware BIOS on the mainstream X86 server platform: one is to complete the BIOS upgrade and upgrade operation through the upgrade tool under the UEFI shell, and the other is to complete the BIOS firmware upgrade through the BMC web and BMC terminal commands. Upgrading and downgrading. These two methods of upgrading the BIOS firmware are the mainstream AMI platform practices, but both have the problem of insufficient security by flashing other image files when the BIOS is upgraded. SUMMARY OF THE INVENTION [0003] In view of this, the purpose of the present application is to provide a BIOS update method, device, device and medium, which can avoid flashing other image files during BIOS update, thereby ensuring the security of BIOS u...
