## Abstract

A method for burning a BIOS chip (108) and a network card chip (107) that are attached on a motherboard (106), includes the steps of: storing a plurality of MAC addresses in a burning device (102); loading a BIOS file and a network card file into the burning device; sending the BIOS file from the burning device to a burning card (104), and burning the BIOS file into the BIOS chip via the burning card; the burning device sending the network card file which includes a MAC address from the burning device to the burning card, and burning the network card file into the network card chip via the burning card; and verifying whether the BIOS chip and the network card chip have been burned correctly.

## Claims

### Claim 1

A method for burning a BIOS chip and a network card chip that are attached on a motherboard, comprising the steps in the following order:
storing a plurality of MAC addresses in a burning device;
loading a BIOS file and a network card file into the burning device;
sending the BIOS file from the burning device to a burning card, and burning the BIOS file into the BIOS chip via the burning card;
sending the network card file which includes a MAC address front the burning device to the burning card, and burning the network cand file Into the network card chip via the burning card; and
verifying whether the BIOS chip and the network card chip have been burned correctly.

### Claim 2 (depends on 1)

The method as described in claim 1, wherein each of the steps of the burning the BIOS file into the BIOS chip via the burning card and the burning the network card file into the network card chip via the burning card comprises the steps of:
sending the file from the burning device to the burning card via a parallel interface;
transforming the file in the burning card into serial data; and
burning the transformed file to the chip via a serial interface.

### Claim 3 (depends on 1)

The method as described in claim 1, wherein the verifying step comprises the steps of:
reading the data stored in the chip by the burning card;
sending the data from the burning card to the burning device; and
comparing the data with the original file by the burning device.

### Claim 4 (depends on 1)

The method as described in claim 1, wherein after the chip is verified to be correctly burned, the burning device scans a barcode of the motherboard, and sends the barcode and the MAC address in the corresponding chip to a server.

### Claim 5 (depends on 4)

The method as described in claim 4, wherein the server recodes the barcode and the MAC address, and compares them with the recoded barcodes and MAC addresses in the server to avoid the same MAC address being used in more than one motherboard.

### Claim 6 (depends on 1)

The method as described in claim 1, wherein before the burning device sends the network card file to the burning card, the burning device checks if the network card chip already contains a MAC address, if yes, the MAC address is added to the network card, if not, the burning device releases a MAC address, and adds it to the network card file.
