Method for realizing parts detection utilizing intelligent equipment firmware
A technology implemented by smart devices and firmware. The redundancy applied in the operation is used for data error detection, response error generation, program loading/starting, etc., which can solve problems such as inconvenient operation, clutter, and incomplete fault information. To achieve the effect of simple operation and not easy to lose

[0068] The first application example:
[0069] Because many times computer users will encounter the computer "no display" failure, that is, press the power button on the computer chassis, under normal circumstances, the computer should execute the BIOS POST process, and display the manufacturer's LOGO or self-check information on the display screen , But sometimes there will be a failure that the monitor does not display after booting. Normally, in addition to the above information, computer users cannot provide more valuable information.
[0070] Using the method of the present invention, a test program module can be added to the BIOS. The function of the test program module is only to make the buzzer or horn on the main board emit a short high-frequency short sound. Since the test program does not have a necessary POST preparation stage, the calling interface of the test program module is set at the point where the computer is powered on and the CPU starts to execute the instruc...
Example
[0075] Second application example:
[0076] In this example, a memory test program module, a CMOS test program module, and a hard disk test program module are embedded in the BIOS. For the process of this example, please refer to Figure 4 , Assuming Figure 4 Where n is 3, where the memory test program module, CMOS test program module, and hard disk test program module correspond to Figure 4 The first, second, and third test program modules in. The computer is powered on, and after POST phase 1 is executed, the POST process is suspended, the call interface 1 corresponding to the memory test program module is started, and the state value of trigger condition 1 is judged. If the trigger condition 1 is valid, the memory test program is called to execute. And the test result information is output in a standardized form through the output device of the computer. The output device can be a buzzer, speaker, display, etc.; for example, the test result of the buzzer is shown in Table 1:
