  • Method and apparatus for detecting conditions for blocking a CPU's receipt of signals returned from a peripheral device
    Patent number: 7353312
    Abstract: A method for determining blocking signals is used to judge whether to block a return signal transmitted to a CPU or not when a system management interrupt (SMI) signal is transmitted to the CPU, wherein the return signal is a signal transmitted by a system chip in response to a triggering command transmitted to the system chip by the CPU. The blocking method includes detecting whether the CPU has transmitted the triggering command to the system chip, and detecting whether the system management interrupt signal is transmitted to the CPU. When the CPU has transmitted the triggering command to the system chip, and subsequently the system management interrupt signal has been transmitted to the CPU, it is judged that the system management interrupt signal is used to extract the values in registers of a computer system. Thereby the return signal transmitted to the CPU is blocked.
