ABSTRACT:
One or more detection circuits are provided for determining the operation of a motherboard prior to placing a microprocessor upon that motherboard. The detection circuit determines a particular way in which the motherboard is configured by ascertaining, for example, a power supply voltage and a clocking frequency output from the motherboard. A probe is used, in combination with the detector circuits, to determine motherboard operation at a socket to which, for example, a microprocessor can be coupled. Jumpers or switches upon the motherboard can be readily found by activating a switch and looking for a response upon the detection circuit output. If a response is not found, the jumper or switch is returned, and another jumper or switch is activated. Once the jumper or switch used for changing system clock speed and/or processor voltage is located, then a display is read as to those parameters to ensure the parameters match the processor specification. Reading the motherboard configuration and/or reconfiguring the motherboard to a different operation parameter proves beneficial in ensuring its output compatibility to a microprocessor to be inserted upon the motherboard socket.
