Disclosed is a control device for preventing hardware strapping fault of a computer system. The computer system includes a central processing unit having a first signal pin, an integrated circuit device having at least one hardware strapping pin, and an external device coupled to the computer system and having a second signal pin. The hardware strapping pin is a multiplexing pin that generates a hardware strapping signal to the central processing unit to perform a hardware strapping operation at the time when the system is being powered on and, after the hardware strapping is completed, is connectable to the second signal pin of the external device. The control device includes a hardware strapping fault prevention circuit coupled between the hardware strapping pin of the integrated circuit device and the second signal pin of the external device to isolate the second signal pin of the external device from the first signal pin of the central processing unit at the time when the system is being powered on.
