1. Technical Field
The present disclosure relates to an apparatus for testing a basic input output system (BIOS) chip.
2. Description of Related Art
Manufacturers may use a diagnostic card to debug a BIOS chip of a device by inserting the card into a special connector set on a motherboard of the device and reserved for that purpose, which takes up precious space of the motherboard. Thus, there is room for improvement in the art.
Many aspects of the present disclosure can be better understood with reference to the following drawing(s). The components in the drawing(s) are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawing(s), like reference numerals designate corresponding parts throughout the several views.
Referring to
The base 10 includes a plate 12 and four sidewalls 14 perpendicularly extending up from sides of the plate 12. The plate 12 and the sidewalls 14 bound a receiving space 100 to house the BIOS chip 30. A plurality of signal pins 16 is mounted on each sidewall 14. When the BIOS chip 30 is inserted into the receiving space 100, the signal pins 16 are electrically connected to the pins 300 of the BIOS chip 30.
Referring to
The pins 202 includes data pins LAD0˜LAD3, a frame signal pin LFRAME#, a clock signal pin CLK, a reset pin RESET#, a power pin P3V3, and two ground pins GND grounded, all connected to the corresponding signal pins 16. Therefore, after the BIOS chip 30 is accommodated in the receiving space 100, the diagnostic card can communicate with the BIOS chip 30 through the connector 20, to debug the BIOS chip 30.
In use, the apparatus is placed on the motherboard 40, with the receiving space 100 accommodating the BIOS chip 30 and the pins 202 extending up. The diagnostic card is engaged with the connector 20. When the motherboard 40 is powered on, the BIOS chip 30 does a power on self test (POST) and sends the POST codes in hex to an input output (I/O) port 80 of the motherboard 40. Consequently, the diagnostic card can communicate with the BIOS chip 30 by accessing the port 80.
While the disclosure has been described by way of example and in terms of preferred embodiment, it is to be understood that the disclosure is not limited thereto. To the contrary, it is intended to cover various modifications and similar arrangements as would be apparent to those skilled in the art. Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
