Problems solved by technology

However, this setting of master and slave BIOS chips on the same motherboard needs to be switched by a two-way switch, that is, manual switching is required.
However, if two BIOS programs are set on the same chip, when there is a problem with the chip, both BIOS programs will be unusable.
Therefore, the traditional method of starting the computer cannot realize the automatic switching and booting of the BIOS when the system or equipment encounters problems, and cannot realize the unattended operation of the system application.

Embodiment Construction

[0031] figure 1 The flow of the method for starting the computer provided by Embodiment 1 is shown, and the specific process is as follows:

[0032] Step S102, start up and power on.

[0033] Step S104, the timer starts working.

[0034] Step S106, select the main BIOS chip through the selection circuit connected with the timer.

[0035] Step S108, check whether the operating system can be booted into the operating system through the BIOS program in the main BIOS chip within the time set by the timer, if yes, go to step S110, otherwise go to step S112.

[0036] If the operating system can be booted into the operating system through the BIOS program in the main BIOS chip within the time set by the timer, it means that there is no problem with the main BIOS chip and the system can be started normally. If the BIOS program in the computer boots into the operating system, it means that there is a problem with the main BIOS chip, and it needs to be booted into the operating syste...

Abstract

A method for starting a computer, comprising the steps of: powering on the computer; starting a timer; selecting a main BIOS chip through a selection circuit connected to the timer; detecting whether the main BIOS chip can pass through the main BIOS chip within the time set by the timer; The BIOS program is guided into the operating system, if so, the timer is turned off, otherwise the secondary BIOS chip is selected by the selection circuit chip, and the system is triggered to restart, and the operating system is guided into the operating system by the BIOS program in the BIOS chip. The above method can automatically switch to booting the operating system from the BIOS chip when the main BIOS chip fails to start normally, without manual intervention, and realizes unattended system application. In addition, a BIOS automatic recovery circuit used in the above method for starting a computer is also provided.

Description

【Technical field】 [0001] The invention relates to computer technology, in particular to a method for starting a computer and a BIOS automatic recovery circuit. 【Background technique】 [0002] With the development of computer technology, industrial computers have been applied to many fields of social production, such as industrial control, data acquisition, environmental monitoring and so on. Most of these occasions require the computer system to work stably for a long time. BIOS (Basic Input / Output System, basic input and output system) is a set of programs solidified on the motherboard of the computer. The startup program, whose main function is to provide the computer with the lowest and most direct hardware setting and control. [0003] In the traditional method of starting a computer, in order to ensure that the system can normally boot, there is a method of starting the computer through dual BIOS, that is, on the same main board, two BIOS chips, master and slave, are ...
