Therefore, extensive research is carried out to solve the above problems, and at present, a professional mainboard detection device is generally used in the market, and although the device can detect the fault problem of the mainboard, the device has the defects of high price, complex detection means, inconvenience in carrying and the like.

ISA bus: the Industry Standard Architecture of Industry Standard is a bus Standard established by IBM company for PC/AT computer, and is a 16-bit Architecture, which can only support 16-bit I/O equipment, and the data transmission rate is about 16 MB/S.

PCI is an abbreviation for Peripheral Component Interconnect (Peripheral Component Interconnect), which is currently the most widely used interface in personal computers.
