Embodiment Construction

[0043] The method for starting the computer system and the computer terminal provided by the present invention will be described in more detail below in conjunction with the accompanying drawings and embodiments.

[0044] The embodiment of the present invention utilizes the concept of trusted delivery to provide a security boot solution, such as figure 2 As shown, the computer system startup method provided by the embodiment of the present invention includes:

[0045] Step 201, running the basic input and output system BIOS program to self-check the hardware status after startup;

[0046] BIOS is a set of programs that are solidified on a ROM chip on the motherboard of the computer. It stores the most important basic input and output programs of the computer, system setting information, self-test programs after startup, and system self-starting programs. Its main function is to provide the computer with the lowest and most direct hardware setting and control.

Abstract

The invention discloses a computer system starting method and a computer terminal. The computer system starting method comprises the following steps of: operating a program self-detection hardware state of a BIOS (Basic Input-Output System) after starting; reading and executing a MBR (Master Boot Record) program in a disk after self-detection; in an MBR program executing program, guiding and loading a trusted guide program; guiding and loading a main starting program stored in the disk after loading the trusted guiding program; in a process of loading the trusted guiding program, reading the main starting program stored in the disk so as to carry out credibility verification; when the credibility verification is not passed, reading the corresponding standby starting program in the disk to replace the main starting program which is not verified; and in a process of loading the main starting program stored in the disk, completing the starting program. According to the computer system starting method and the computer terminal provided by the invention, the starting process is safe and trusted.

Description

technical field [0001] The invention relates to the technical field of device startup, in particular to a computer system startup method and a computer terminal. Background technique [0002] In a computer system, the startup process is the basis of all behavior of the system. The startup process not only loads the operating system itself, is responsible for initializing the physical equipment of the computer system and the status of the operating system itself, but also starts the trusted process and related service programs necessary for the system to maintain normal operation. Since any errors and omissions in the boot process may cause the operating system to enter an unpredictable and dangerous state, it is very important to ensure the safety of the boot process. [0003] In the Linux system platform, such as figure 1 As shown, the existing computer system startup process mainly includes the following processes: [0004] Step 101, after the system is powered on, firs...
