Abstract: The present invention relates to an adjustable clock skew apparatus and method for generating clock signals, which resolves the drawbacks of costing a user much time and effort to adjust clock skews of all components on a motherboard. In order to accomplish the object, the present invention proposes three operating modes: hardware setup, software setup or a mixture of hardward and software setup. A user just needs to adjust a plurality of exterior switches or to adjust a Basic Input Output System (BIOS) of the motherboard to modify the parameter of clock skew, and clock signals with necessary clock skews will be obtained.

Abstract: An automatic stable frequency detector and a method of finding a stable operating frequency in a computer system. The detector includes a central processing unit, a monitoring timer and a clock generator for providing a clocking frequency to the computer system. The method is capable of saving much user labor for calibrating the operating frequency of the motherboard of a personal or notebook computer. This is because personal or notebook manufacturers can set up the computer system to work at the highest stable operating frequency of whatever computer system through software or hardware.
