Abstract

The invention provides a computer mainboard with a fault diagnosis function, comprising a computer mainboard body, as shown in Fig 1, wherein a fault diagnosis CPLD chip is arranged on the computer mainboard body, and connected with the south bridge on the computer mainboard body through an LPC bus and also connected with an onboard LED indicator light on the front panel of an embedded CPCI system. Compared with the prior art, the computer mainboard with the fault diagnosis function has the following advantages that the form of onboard CPLD is used, so that each product is provided with a debugging indication interface, and fault codes can be output by an onboard light emitting diode; standard debugging equipment as well as specific interfaces are not needed, flexible debugging is achieved, a fault can be directly positioned in an industrial field, thus being convenient and rapid, and product maintainability is improved; product maintenance cost and complexity are reduced; and the fault can be rapidly positioned, and product troubleshooting response time is shortened.

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 ...
