Abstract
A CPU plug-and-play method includes driving the I/O chip of a computer to generate two reset signals when the computer is booted to respectively reset the ISA and PCI buses of the computer main board, at the same time issuing a CPU control signal to a system logic chip of the computer to gain control of the CPU working frequency setting operation, and transmitting a selected working frequency set by the user via system firmware to a multiple frequency factor control circuit through a universal bus. The multiple frequency control circuit generates and transmits a multiple frequency factor to the CPU by applying a reset signal to the system chip set in response to the multiple frequency factor to generate a CPU reset signal which instructs the CPU to adapt the working speed in accordance with the new multiple frequency factor so that no jumper or other switch is needed to be manipulated in changing working frequency. Thus a plug-and-play method for CPU is provided.
