Abstract

The present invention provides a computer mainboard with a failure diagnosis function. The computer mainboard comprises a computer mainboard body. As shown in Figure 1, a failure diagnosis CPLD chip is arranged on the computer mainboard body, the failure diagnosis CPLD chip is connected to a south bridge on the computer mainboard body by means of an LPC bus, and the failure diagnosis CPLD chip is connected to an on-board LED indicator on a front panel of an embedded CPCI system. Compared with the prior art, the present invention has the following advantages: by using the on-board CPLD manner, each block of product has a debug indication interface, and a failure code can be output by means of an on-board light-emitting diode; a standard debug device does need to be used, and a special interface is not needed, and debugging is flexible, and failure positioning can be performed directly on an industrial site, which is convenient and quick, thereby improving maintainability of products; the costs and complexity of product maintenance are reduced; and failures can be positioned rapidly, which shortens response time of product failure isolation.

Description

technical field [0001] The invention belongs to the technical field of computer motherboard testing, and in particular relates to a computer motherboard with a fault diagnosis function. Background technique [0002] The design of the X86 computer system is very complicated. In the booting stage, the basic system initialization and configuration are performed by the BIOS, and then the output display is displayed. Before the display output, there is no way to output the fault during the power-on process of the board through the display terminal; in order to facilitate maintenance and debugging, The traditional BIOS will output a series of diagnostic codes through port 80 during the execution of the BIOS to track the execution process of the BIOS and locate faults during the power-on process of the system. [0003] Traditional PCs generally use motherboard fault diagnosis cards: they use the detection results of the BIOS internal self-test program in the motherboard to display ...
