Embodiment Construction

[0035] Please refer to FIG. 1 , which is a system block diagram of an embodiment of the present invention. As shown in FIG. 1 , the motherboard error detection system of the present invention includes a motherboard 10 and a detection device 20 .

[0036] Motherboard 10, is made of circuit substrate and a plurality of electronic parts, and it comprises chipset (for example, south bridge chip, north bridge chip), central processing unit, memory, input / output chip, input / output interface, basic input / output system (Basic Input Output System, BIOS) and so on.

[0037] The light signal output port 11 is arranged on the main board 10 to output the light signal data corresponding to the test result of the main board 10, and the light signal output port 11 can be practically transmitted through an asynchronous serial transmission (Universal Asynchronous Receiver / Transmitter; UART) interface (for example , RS-232, RS-485) or peripheral component connection interface (Peripheral Compon...

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...
