Chassis type determination in an electronic system

A computer system comprising:

• a circuit board;
• a system processor;
• a chassis, the chassis being of a chassis type, the circuit board and the system processor are located within the chassis;
• a chassis detection circuit providing a type signal indicative of the presence of a structure of the chassis;
• and
• wherein the presence of the structure is indicative of the chassis type;
• wherein the type signal is indicative of the chassis type.

A computer system comprising:

• a circuit board;
• a system processor;
• a chassis, the chassis being of a chassis type, the circuit board and the system processor are located within the chassis;
• an electrically conductive surface physically coupled to the circuit board;
• a chassis detection circuit including a pull up resistor having a first end electrically coupled to the electrically conductive surface;
• wherein the chassis detection circuit provides a type signal dependent upon the voltage level of the first end of the pull up resistor, the type signal is indicative of the presence of a grounded structure of the chassis electrically contacting the electrically conductive surface,
• wherein the presence of the structure is indicative of the chassis type.

A computer system comprising:

• a circuit board;
• a system processor;
• a chassis, the circuit board and the system processor are located within the chassis;
• means for detecting structural differences of the chassis and providing a signal indicative thereof.
