Computer hardware operating mode setting circuit

A computer hardware operating mode setting circuit for use with a hardware module that is provided with an operating mode setting port, which comprises;

• a circuit substrate;
• a first pad, which is provided on the circuit substrate, and which is electrically connected to the operating mode setting port of the hardware module;
• a second pad, which is provided on the circuit substrate, and which is electrically connected to a system voltage;
• a third pad, which is provided on the circuit substrate, and which is electrically connected to a grounding point;
• a first resistor, which is selectively connected between the first pad and the second pad for electrically connecting the system voltage to the operating mode setting port of the hardware module for the purpose of setting the operating mode setting port at a logic-HIGH voltage state;
• and
• a second resistor, which is selectively connected between the first pad and the third pad for connecting the operating mode setting port of the hardware module to the grounding point for the purpose of setting the operating mode setting port at a logic-LOW voltage state.
