Abstract

A PCI-E debug card includes an insertion part, a low-pin-count pin set, a power pin, a ground pin, a decoder and a display unit. The insertion part is for connecting to a PCI-E slot. The low-pin-count pin set includes a reset pin, a clock pin and a plurality of data pins, each of which corresponds to reserved pins of the PCI-E slot. The power pin and the ground pin are disposed on the insertion part and correspond respectively to a slot power pin and a slot ground pin of the slot. The decoder decodes test data from the low-pin-count pin set to be a post code which is then showed by the display unit.

Claims

1. A PCI-E debug card applicable to a PCI-E slot, comprising:

an insertion part for connecting to the PCI-E slot;

a low-pin-count pin set on the insertion part, comprising;

a reset pin for a reset signal transmission;

a clock pin for a clock signal transmission; and

a plurality of data pins, when the insertion part is connected with the PCI-E slot, the data pins, the reset pin and the clock pin contact with reserved pins of the PCI-E slot;

a power pin on the insertion part corresponding to a slot power pin of the PCI-E slot and electrically connected to a power source;

a ground pin on the insertion part corresponding to a slot ground pin of the PCI-E slot and electrically connected to a ground;

a decoder for decoding test data from the low-pin-count pin set to be a POST code; and

a display unit showing the POST code.

2. The PCI-E debug card of claim 1, further comprising a power indicating device electrically connected with the power pin for indicating a power supply status.

3. The PCI-E debug card of claim 1, wherein the display unit is an LED indicator.

4. The PCI-E debug card of claim 1, wherein the display unit is a regular LED bulb.

5. The PCI-E debug card of claim 1, wherein the data pins are in number of five.

6. The PCI-E debug card of claim 1, wherein the data pins and the reset pin are disposed on a bottom side of the insertion part and the clock pin is disposed on a top side of the insertion part.

7. A PCI-E debug card applicable to a Mini PCI-E slot, comprising:

a circuit board complying with a Mini PCI-E specification dimension for connecting to the Mini PCI-E slot;

a low-pin-count pin set, comprising;

a reset pin for a reset signal transmission;

a clock pin for a clock signal transmission; and

a plurality of data pins, when the insertion part is connected with the Mini PCI-E slot, the data pins, the reset pin and the clock pin contact with reserved pins of the Mini PCI-E slot;

a power pin on the insertion part corresponding to a slot power pin of the Mini PCI-E slot and electrically connected to a power source;

a ground pin on the insertion part corresponding to a slot ground pin of the Mini PCI-E slot and electrically connected to a ground;

a decoder for decoding test data from the low-pin-count pin set to be a POST code; and

a display unit showing the POST code.

8. The PCI-E debug card of claim 7, further comprising a power indicating device electrically connected with the power pin for indicating a power supply status.

9. The PCI-E debug card of claim 7, wherein the display unit is an LED indicator.

10. The PCI-E debug card of claim 7, wherein the display unit is a regular LED bulb.

11. The PCI-E debug card of claim 7, wherein the data pins are in number of five.

12. The PCI-E debug card of claim 7, wherein the data pins and the reset pin are disposed on a bottom side of the circuit board and the clock pin is disposed on a top side of the circuit board.
