Embodiment Construction

[0028] For ease of understanding, the following explanations are made to some nouns appearing in the present invention:

[0029] BIOS: Basic Input Output System (Basic Input Output System), which is a set of programs solidified on a ROM chip on the motherboard of the computer, which stores the most important basic input and output programs of the computer, self-test programs and system Self-starting program, which can read and write specific information about system settings from CMOS. Its main function is to provide the computer with the lowest and most direct hardware setting and control.

[0030] MCU: Microcontroller Unit (Microcontroller Unit), which appropriately reduces the frequency and specifications of the Central Process Unit (CPU), and integrates memory (memory), counter (Timer), USB, A / D conversion, UART, Peripheral interfaces such as PLC, DMA, and even LCD drive circuits are integrated on a single chip to form a chip-level computer, which can be used for differen...

Abstract

The invention belongs to the technical field of mainboard testing and discloses a mainboard problem testing diagnosis card. The mainboard problem testing diagnosis card comprises an MCU (microcontroller unit), a memory register, a buffer register, a logic circuit unit and a first LCD (liquid crystal display), wherein the MCU is in two-way communication with the memory register and the buffer register, and an output end of the MCU is in control connection with the first LCD; an output end of the buffer register is in control connection with the first LCD through the logic circuit unit. The invention further discloses a mainboard problem testing diagnosis method. The method comprises the steps that the MCU receives a POST card fault code; the MCU calls text messages, corresponding to the POST card fault code, in the buffer register; the MCU judges whether the capacity of the text messages is higher than the maximum display capacity of the first LCD. With adoption of the mainboard problem testing diagnosis card and method, the POST card fault code can be converted into corresponding literal explanation, the literal explanation is displayed on the LCD in a moving and circulating manner, and the working efficiency is increased.

Description

technical field [0001] The invention belongs to the technical field of mainboard testing, in particular to a diagnostic card and a diagnostic method for testing mainboard problems. Background technique [0002] Traditional diagnostic cards use digital tubes as display technology, and generally display two-digit or multiple two-digit codes. Maintenance personnel must check the corresponding explanations according to the displayed codes, and then know the fault explanations represented by the codes displayed on the diagnostic card. This will cause the range of users of the diagnostic card to be limited to professionals, and non-professionals will be discouraged when they see the cold codes. When a simple fault occurs on the motherboard, they need to seek help. This also leads to the reason why diagnostic cards cannot serve the general public. If the cold codes can be translated into text and displayed, with simple maintenance suggestions attached, ordinary users can deal wit...
