电脑主板的运作和其他知识（国外英文资料） Operation of computer motherboards and other knowledge. TXT it is a taboo collapse of The Times, no one stopped to you, only you and stop yourself, the less the more taboo you achievement. There are many levels of inferiority, and the highest level of inferiority is a talent for boasting about what you do. Automatic CPU detection Old-style motherboards, which require users to set their own CPUs external frequency, frequency and voltage, etc. (usually by jumping wire). Now the main board of production can automatically detect these parameters and set them correctly and save them in the CMOS. There is no need to open the box when CMOS drops the power. In addition, the motherboard now has the CPU temperature detection and alarm function that the old motherboard does not have. The CPU is too hot, which can cause the system to be unstable or dead, or even damage the CPU. Therefore, it is important to test the temperature of the CPU. It will issue a warning test when the CPU temperature is outside the safe range. There are two types of temperature probes: one that is integrated into the processor and relies on the BIOS support; The other is external, which can be seen on the main board, usually a thermistor. They all change their electrical resistance by changing temperature, which allows the temperature detection circuit to detect changes in the resistance, changing the temperature. Hardware error detection Due to hardware installation errors, incompatible or hardware damage, easy to cause a hardware error, leading to light abnormal operation, fault or system cannot work. In this case, you can only use the BIOS alerts, hardware substitution method, or the DEBUG card to find the cause of the problem. However, these methods are not easy to use, and the knowledge of the user is high, not applicable to ordinary users. In response to this problem, the mainboard manufacturers are now adding a lot of human design to make it easier for users to quickly and a
