## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a baseboard testing interface and a testing method thereof, and more particularly, to a baseboard testing interface, on which a first connection interface is configured on a motherboard, and a second connection interface is configured on a debugging adapter, such that when the debugging adapter is slantly plugged into a memory slot of the motherboard, the second connection interface is contacted with the first connection interface in order to transmit the signals between the baseboard and the debugging adapter, and a testing method thereof.
2. Description of the Related Art
Currently, in the computer motherboard testing device, a debugging adapter with the testing and display functions is plugged into a motherboard's slot, e.g. an ISA slot or a PCI slot, to perform the testing and debugging functions on the motherboard.
A PCI debugging device used on the PCI interface of the computer motherboards had been disclosed in the “PCI Debugging Device, Debugging Method, Chipset and System Applying the Same” in the approved R.O.C. Patent No. 508490 (applied on Aug. 27, 1999 and published on Nov. 1, 2002). The approved patent comprises a PCI debugging device for debugging a system with a PCI interface. Wherein, the PCI interface comprises a request signal, a permission signal and an object ready signal, and the system has a debugging mode. When the system is on the debugging mode and the request signal is activated, the permission signal will not be terminated by the system. The PCI debugging device comprises: a switch circuit for setting up a to-be-debugged command signal; a system data display circuit, which is coupled to the PCI interface for displaying the data on the PCI interface and issuing a real-time command signal; a decoding comparator circuit, which is coupled to the switch circuit and the system data display circuit for decoding the real-time command signal and comparing with the to-be-debugged command signal in order to generate a same-command instruction signal; and a latch circuit with a reset input, which is coupled to the decoding comparator circuit for latching a trigger signal, so as to activate the request signal.
It is quite inconvenient when applying the PCI interface debugging adapter mentioned above on the motherboard of the notebook computers. It is because the general notebook computers are quite small, when it is required to plug in the PCI interface debugging adapter to the PCI slot to perform the testing function, the notebook computer's cover has to be removed first. Accordingly, it inevitably increases the operation's difficulty.
SUMMARY OF THE INVENTION
Therefore, it is an objective of the present invention to provide a baseboard testing interface and a testing method thereof. In the present invention, the debugging adapter is fixed on the memory slot on the motherboard, and the required electricity power and the ground signal are provided through the memory slot, such that the maintenance staff only needs to remove the cover of the memory slot to repair the notebook computer.
It is another objective of the present invention to provide a baseboard testing interface and a testing method thereof. In the present invention, a first connection interface is configured on a motherboard, and a second interface connection interface is configured on a debugging adapter. When the debugging adapter is slantly plugged into a memory slot of the motherboard, the second connection interface is contacted with the first connection interface, such that the signals can be transmitted between the baseboard and the debugging adapter.
To achieve the foregoing objectives, the present invention provides a baseboard testing interface, which comprises: a baseboard, on which a plurality of first electronic components, a plurality of signal lines, and a first connection interface are configured, and the first electronic components are coupled to the signal lines; a slot disposed on the baseboard for an external interface adapter to plug in; and a debugging adapter that is plugged into the slot, and a plurality of second electronic components and a second connection interface are configured thereon; when the debugging adapter is plugged into the slot and fixed on the baseboard, the second connection interface is contacted with the first connection interface, such that the signals can be transmitted between the baseboard and the debugging adapter. In addition, the present invention further provides a baseboard testing method.

Wherein, the first connection interface 15 comprises a plurality of contacts 151, which are directly formed on the baseboard 10. Ten contacts are exemplified in the present embodiment for easy explanation in order to respectively represent the PCLK_PCI_SIO, LPC_AD0, LPC_AD1, LPC_AD2, LPC_AD3, LPC_FRAME#, PCIRST#, LPC_DRQ1#/E51_RXD, SERIRQ/E51_RDX, and +3VALW signals, but they are not necessarily limited to be ten contacts. When the contacts 151 are used to bind the debugging adapter 30 with the baseboard 10, the debugging adapter 30 is vertically mapped onto an area of the baseboard 10, and the first electronic components 11 are configured on a surface vertical to the baseboard 10.
The slot 20 is disposed on the baseboard 10 for an external interface adapter to plug in, wherein the external interface adapter is, including but not necessarily limited to a memory adapter or a display adapter. In the present embodiment, the slot 20 is a S0-DIMM memory adapter slot on the baseboard 10 and is built in the shape of . In addition, an elastic long-shaped fixed latch and a plurality of elastic metal pins (not shown in the diagram and since these techniques are known in the prior art, its detail is intentionally omitted herein) are configured on both sides of the slot 20, such that the debugging adapter 30 can be fixed on the  shaped slot 20. Additionally, the first connection interface 11 is preferably disposed on the baseboard 10 within the range of the  shaped slot 20.
The debugging adapter 30 can be plugged into the slot 20, and a plurality of second electronic components 31 and a second connection interface 35 are further configured thereon. Wherein, the second electronic components 31 further comprise a decoding chip 311 and a display device 312. The decoding chip 311 is coupled to the second connection interface 35 and the display device 312. The decoding chip 311 receives a signal on the baseboard 10 through the second connection interface 35. Then, the received signal is decoded by the decoding chip 311 based on the Intel Low Pin Count Interface Specification to generate a message code, which is subsequently displayed by the display device 312.

Meanwhile, the signals can be transmitted between the baseboard 10 and the debugging adapter 30. The decoding chip 311 on the debugging adapter 30 is designed according to the Intel Low Pin Count Interface Specification. The signals on the baseboard 10 are decoded by the decoding chip 311 in order to generate a message code, which is subsequently displayed by the display device 312. Then, after looking up the message code from the Intel Error Code List, the developers and the customer service engineers can comprehend whether the baseboard 10 is out of order and decide whether to fix it or not. Accordingly, the present invention effectively resolves the disadvantages of the conventional PCI or ISA slot debugging adapter. In addition, unlike in the conventional technique, the cover of the notebook computer has to be taken apart before the debugging adapter can be plugged into the PCI slot. When using the baseboard testing interface of the present invention to test the notebook computer's baseboard, as long as the cover of the memory slot is removed, the developers and the customer service engineers can plug the debugging adapter 30 into the slot 20 to check the status.
