Electronic apparatus and detection method using the same

An electronic apparatus comprising:

• a processor comprising a first bus compatible with a first standard;
• a platform controller coupled to the processor, wherein the processor is connected to a peripheral device of the electronic apparatus through the platform controller or the first bus by the first standard;
• an auxiliary controller connected to the platform controller through the first bus and is coupled to the processor, wherein the processor controls the auxiliary controller through a second bus and the platform controller;
• and
• a sensor device connected to the auxiliary controller through an Intelligent Platform Management Bus (IPMB), wherein the sensor device is tested by the auxiliary controller according to an instruction received from the processor through the second bus,
• wherein the auxiliary controller receives a detection signal to detect the processor, the platform controller, or the peripheral device in the electronic apparatus through the first bus according to the detection signal,
• wherein the auxiliary controller is connected to the platform controller through the first bus and the second bus directly, and separate connections of the first bus and the second bus are connected in parallel for connecting between the platform controller and the auxiliary controller,
• wherein the first standard is the Peripheral Component Interconnect Express,
• wherein the auxiliary controller is set as one of a plurality of terminals that are compatible with the first standard, and the auxiliary controller detects the processor, the platform controller, or the peripheral device in the electronic apparatus through a peer-to-peer transaction function in the first standard.
