    • 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.
    • 公开了一种用于防止计算机系统的硬件捆扎故障的控制装置。 计算机系统包括具有第一信号引脚的中央处理单元,具有至少一个硬件捆扎引脚的集成电路器件和耦合到计算机系统并具有第二信号引脚的外部器件。 硬件捆绑引脚是多路复用引脚,其产生硬件捆绑信号到中央处理单元以在系统上电时执行硬件捆扎操作,并且在硬件捆扎完成之后可连接到第二信号 外部设备的引脚。 该控制装置包括:硬件捆扎故障预防电路,其耦合在集成电路装置的硬件捆扎销和外部装置的第二信号引脚之间,以将外部装置的第二信号引脚与中央处理单元的第一信号引脚隔离 在系统上电时。
