Mainboard error detection method

Abstract

The invention discloses a motherboard error detection method. A detection device is connected to a signal output port to obtain related error detection information. The method comprises the steps that corresponding signal data of each program segment of a starting up self test program in the motherboard is set; the starting up self test program is executed in the motherboard, the program segments are executed in sequence, and the corresponding signal data is output to the detection device through the signal output port; the detection device receives and stores the signal data in sequence; the detection device searches the corresponding character string information of the signal data in sequence according to a pre-established signal meaning cross reference list; the detection device displays the corresponding character string information of the signal data in sequence. The invention ensures that maintenance personnel can be aware of the content of an error detecting code without checking an error detecting code technical manual, and provides complete error detection information to facilitate the maintenance personnel to judge the cause of the error of a computer system, thereby improving the motherboard detection efficiency.

Description

technical field [0001] The invention relates to a method for preventing errors by using software testing or debugging, in particular to a motherboard error detection method. Background technique [0002] In the current Power On Self Test (POST) program on the motherboard, most hardware devices such as debug cards are used to perform testing procedures. When the debug card detects a wrong hardware device, it will display the corresponding detection Wrong code. At this time, the detection or maintenance personnel need to look up the table separately to know the meaning represented by the error detection code. Such a detection process is time-consuming and inefficient, and because each Basic Input / Output System (Basic Input Output System, BIOS) program Paragraphs may be repeatedly called and executed in the test program. Therefore, when an error occurs in a certain program segment, the inspection or maintenance personnel must use the relationship between the previous and subse...

Problems solved by technology

[0004] Although the above-mentioned patent application has disclosed a technical means of transmitting the relevant error detection information to the existing information equipment in a wireless transmission mode, and allows the detection or maintenance personnel to read any error detection code technical manual In this case, you can understand the content of the error detection code, but like a general error detection program, it will only display the error detection information corresponding to the step where an error occurred in the computer system, and cannot display the complete test program flow information. For detection or maintenance personnel In terms of error detection and interpretation, due to the lack of relevant error detection information before and after the error occurred, the content of the information that can be obtained is slightly incomplete
