Method and system for logging into user diagnostic system by stimulating BIOS function key

Abstract

The invention discloses a method for logging into a user diagnostic system by stimulating a BIOS function key. The method comprises the steps that a host carries out power on self test, a picture for reminding a user to press a certain key is displayed, counting down with certain preset time is carried out, a specific operating system disk partition is detected when the certain key is pressed down during counting down, a start file in the disk partition is loaded, an operator logs into a specific operating system according to the start file, and then a hardware diagnostic system is executed. According to the method, the BIOS function key is stimulated through software, the certain key is pressed down during counting down, the operator logs into the specific operating system, the hardware diagnostic system is executed, the operating system menu selection picture is concealed, user selection troubles are reduced, and host hardware fault diagnosis carried by maintaining staff is facilitated.

Description

technical field [0001] The invention relates to a method and a system for simulating a BIOS function key to enter a user diagnosis system. Background technique [0002] It is hoped that the PC or server shipped to the customer will have a diagnostic system, so that there will be two or more operating systems in the hard disk shipped, one is an office or service operating system, such as Windows OS , one is an operating system for diagnosing host hardware failures, such as Linux with user diagnostics. When the host hardware fails, it is necessary to find out the faulty part, and you can directly enter the fault diagnosis system by pressing the button before the system starts, so as to diagnose the specific fault. [0003] In host computers with dual operating systems, there is generally an operating system menu selector, through which the corresponding operating system can be entered. It is hoped that the menu selector of the operating system will not appear. When the syste...

Problems solved by technology

[0004] The general way to achieve the above functions is to add key functions during the boot process of the BIOS system. The BIOS records the key values ​​in the keyboard buffer, and then the corresponding software program reads the value of the keyboard buffer to determine whether the key has been pressed before entering the corresponding diagnostic system. However, this method There are certain limitations. If there is a need to change buttons or modify information, the BIOS department needs to re-modify and re-flash the BIOS firmware, which will increase the workload.
