The manufacturer can read the motherboard fault code information in some ways.There are many PCB motherboard manufacturers in the world. Each manufacturer of PCB motherboards is different, and each manufacturer open testing ports are different, Even some motherboards do not provide the code output function of PCI, LPC or PCI-E.
