Power-on self-detection method

Abstract

The invention discloses a boot self-test method, which is applied to a hardware test program that needs to load test firmware in a basic input / output system of a computer. It includes the following steps: (a) executing the boot self-test program; (b) executing the When the hardware testing program of the power-on self-testing program is reached, the firmware is tested in a first order to test at least one hardware device; (c) when the hardware testing program returns an error value, the error message corresponding to the hardware testing program is output to the memory; (d) Restart the computer, load the next-order detection firmware from the memory to the basic input / output system, and execute the hardware test program with the next-order detection firmware; and (e) when the hardware test program returns the correct value, then continue to execute the boot self The detection program, wherein, in the step (e), when the hardware test program still returns an error value, then return 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
