Description of the invention (\) The present invention relates to a method and circuit for automatically setting the power supply voltage of the central processor supplied by a personal computer motherboard, especially one that can automatically adjust the central processor Voltage circuit and method design. According to the press, due to the rapid technological change and the development of computer hardware technology, there are constantly faster and more powerful central processing units (CPUs) introduced, which makes the product life cycle shorter, such as 80486 or Pent, which was still the main product last year. i um 75, 90, etc. are now replaced by Pent i um 1 33, 166 and even Pentium 200. The fast speed makes it difficult for consumers and manufacturers to withstand. Only by accelerating the pace of research and development can we keep up with the trend of the times. Therefore, in response to this phenomenon, most manufacturers design the motherboard to be suitable for a variety of central processors, that is, a motherboard can be replaced with Pentium 133 ~ 200 according to user needs. The design of the motherboard must be changed, but although the aforementioned central processor is also produced by INTEL, the required supply voltage value is also different, and when the user wants to replace the central processing of other factories Devices, such as AMD 5x86, CYRIX 5x86 '6x86, etc., each factory has its own voltage settings, so users must pay attention to the replacement of the central processing when replacing the central processing unit * The voltage and the power supply adjusted to the corresponding voltage, so can the normal operation of the central processor, of a given system which maintained the ear.
