Classification: G06F

Abstract:
A CPU plug-and-play method for permitting a user to set a desired working frequency of a computer CPU through firmware of the computer, the working frequency setting operation comprising the steps of:using an I/O chip of the computer to generate a reset signal for ISA and PCI buses and applying a CPU bus control signal to a system logic chip to gain control of a CPU frequency setting operation;transmitting the desired working frequency set by the user to a multiple frequency factor control circuit via a universal bus;the multiple frequency factor control circuit generating a multiple frequency factor which is transmitted to the CPU and a chip reset signal which is transmitted to the system logic chip; andthe system logic chip generating a CPU reset signal to reset the CPU so as make the CPU reset by adapting the working frequency set by the user;wherein the working frequency setting operation provides a setting signal which changes the CPU working frequency to achieve the plug-and-play operation of the CPU.
