Problems solved by technology

[0002] If the basic input and output system (Basic Input Output System, BIOS) and other boot programs (also known as boot systems) in electronic equipment are attacked by some illegal operations, it will cause the electronic equipment or device where the boot program is located to run abnormally.
[0003] At present, the bootloader can only be restored through some methods after the bootloader is attacked, but it cannot reduce the illegal attacks on the bootloader

Abstract

The invention provides a control method and electronic equipment. The electronic equipment comprises a controller; a first memory connected with the controller and at least storing a guide system; a second memory which is connected with the controller and is used for storing update data of the boot system; wherein after the electronic equipment completes power-on self-test, the controller controls the first memory to be in an inaccessible state and controls the second memory to be in an accessible state. According to the scheme of the invention, illegal attacks suffered by the guidance system can be reduced.

Description

technical field [0001] The present application relates to the technical field of data processing, and more specifically, to a control method and electronic equipment. Background technique [0002] If a boot program (also referred to as a boot system) such as a Basic Input Output System (BIOS) in an electronic device is attacked by some illegal operations, it will cause abnormal operation of the electronic device or device where the boot program is located. [0003] At present, the bootloader can only be restored by some methods after the bootloader is attacked, but the illegal attacks received by the bootloader cannot be reduced. Contents of the invention [0004] The present application provides a control method and electronic equipment. [0005] Among them, an electronic device, including: [0006] controller; [0007] The first memory is connected to the controller and stores at least a boot system; [0008] A second memory, connected to the controller, for storing ...
