| Abstract: | Mainboard can generally be divided into six circuits,the boot is one of the circuits,and also a very important part.South Bridge and I/O circuits are based on the I/O models differ.Once you master the principle of the Southbridge and I/O circuit composed of the boot circuit,you will find the reason of the mainboard cann’t boot according to the schematic diagram of the principle,and then troubleshoots purposes quickly and accurately. |
