Power-on self-detection method

Abstract

The invention discloses a startup self-detection method used in a hardware detecting program which needs to load a detecting firmware inside the basic input / output system of a computer. The method includes the following steps: (a) a startup self-detection program is executed; (b) when the hardware detecting program of the startup self-detection program is executed, a first sequential detection firmware tests at least one hardware device; (c) when a hardware testing program returns an error value, an error information corresponding to the hardware testing program is output to a memory; (d) a computer is restarted, and a subsequential detection firmware which is loaded to a basic input / output system from the memory executes the hardware testing program; (e) when the hardware testing program returns a correct value, the startup self-detection program is executed continuously; in addition, when the hardware testing program still returns an error value in the step (e), the process returns to the step (c).

Description

technical field [0001] The invention relates to a power-on self-detection method, in particular to a power-on self-detection method capable of adjusting detection configurations for repeated detection. Background technique [0002] In the current basic input / output system program development process, the tester has to test the hardware device through several restart procedures and several times of power on self test (POST) to verify the basic input / Exit the system program or find other errors. The main task of the power-on self-test program is to detect whether some key devices (such as memory and display card) in the computer system exist and whether they can work normally, and the above-mentioned test process is large. Some are recorded and tested manually (for example, manually rebooting), so the test quality, efficiency and reliability need to be improved. [0003] Referring to China Taiwan Patent Publication No. 200619965, this patent application discloses a method f...

Problems solved by technology

[0006] Although the above-mentioned patent application has been able to automatically perform multiple tests and record the results of each test, it cannot provide multiple configuration values ​​to test each hardware device repeatedly, so it is necessary for the assistant testers to find out the real error and propose an effective improvement plan The demand is still unsatisfied, so the above method still needs to be improved
