Computer system starting method and computer terminal

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...

Problems solved by technology

If there are unpredictable problems such as file corruption during the transfer process, the device board cannot be started normally after the upgrade is forced

[0024] 2) When GRUB fails to start, there is no backup start function;

[0025] At present, most x86 architecture boards do not have active / standby protection for the GRUB part. That is, when GRUB fails to start, because there is no backup GRUB locally, the board starts abnormally, and manual intervention is required to prolong the time to solve the problem.
