Problems solved by technology

[0004] However, in the traditional method of starting a computer system, when the boot device fails or the boot device needs to be changed due to production requirements, manual intervention is required to change the default boot sequence, that is, the user needs to enter the BIOS to reset the default boot sequence, and cannot automatically switch. , not convenient
In addition, because the traditional method is to implement the default boot order through CMOS registers, when COMS is powered off or performs all checks and errors are found, the default boot order will be changed, and the security and reliability are weak.

[0029] Such as figure 1 As shown, a method for starting a computer system includes the following steps:

[0030] In step S110, turn on the power.

[0031] In step S120, the boot device is detected during the power-on self-test phase, and a list of boot devices is generated. After starting up, BIOS (Basic Input Output System, basic input and output system) enters the stage of power-on self-test (PowerOn SelfTest, that is, POST stage), detects all boot devices in the stage of power-on self-test, obtains the type of boot device and the location etc. Record detected boot devices in the boot device list.

[0032] In step S130, read the boot sequence modification flag, and generate a corresponding boot sequence list according to the boot sequence modification flag and the boot device list. In one embodiment, the boot sequence change flag and the corresponding boot sequence rule are set in advance, and the boot sequence change flag is stored in the BIOS chip. The boot sequence r...

[0038] Such as figure 2 As shown, in the second embodiment, the specific process of the method for starting the computer system is as follows:

[0039] In step S210, turn on the power.

[0040] In step S220, the stability of the boot device is detected during the power-on self-test phase. Boot device stability refers to boot device failures or potential problems.

[0041]In step S230, a boot device list is generated, and boot devices whose stability is lower than the first threshold are excluded from the boot device list. The BIOS detects all boot devices in the power-on self-test phase. For a boot device whose stability is lower than the first threshold, that is, the boot device has a fault or a potential problem, the boot device will not be added to the boot device list, thereby ensuring The boot device in the boot device list is a device with high stability, which avoids errors that may occur when the operating system is subsequently loaded.

[0046] Such as image 3 As shown, on the basis of the first and second embodiments, the third embodiment further includes the following steps after loading the operating system:

[0047] In step S310, it is judged whether the current boot device supports SMART technology, if yes, go to step S320, otherwise go to step S330. The current boot device is the boot device where the current operating system is located; SMART technology is Self-Monitoring Analysis and Report Technology (Self-Monitoring Analysis and Report Technology), the boot device supports SMART technology, and the BIOS can monitor the current boot device in real time.

[0048] In step S320, the current boot device is monitored.

[0049] In step S330, the user application program is executed. If the boot device where the current operating system is located does not support SMART technology, the user application program will be executed directly. The user application program can be a pre-set operation, such as runn...

Abstract

The invention provides a method for starting up a computer system, comprising the following steps of: performing start-up and power on; detecting guide devices at a power-on self-checking phase and generating a guide device list; reading a guide order change flag bit, and generating a guide order list according to the guide order change flag bit and the guide device list; and loading an operating system according to the guide order list. With the method provided in the invention, when the guide device is changed or the previous guide device is connected to a different channel, a BIOS (Basic Input-Output System) is capable of automatically changing the default guide order so that a user does not need to enter the BIOS to reset the default guide order; and without manual intervention, the convenience is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of computers, in particular to a method for starting a computer system. 【Background technique】 [0002] Starting a computer system from a boot device is usually after the computer is turned on and powered on, and the BIOS loads an operating system according to a default boot sequence pre-specified by the user. The traditional method of setting the default boot order is that the user enters the BIOS to set the default boot order, and realizes it through the power-on default value of the CMOS (Complementary Metal Oxide Semiconductor, Complementary Metal Oxide Semiconductor) register. The boot sequence loads the operating system. [0003] In the production process of enterprises, in order to realize automated production, unattended equipment, save production costs, and reduce errors caused by manual operations, people usually hope that computers can automatically complete the switching of boot devices. For ...
