Description
Technical Field
The invention relates to the technical field of computer production, in particular to a method for updating a media access control address based on a serial port.
Background
The computer internet technology is developed to the present, and the production process is continuously improved. However, when the motherboards are produced in the factory at present, the media access control addresses (MAC addresses) on each motherboard still need to be manually written under the DOS by using batch files, and a larger manufacturer needs to boot up to the lower side of the DOS to be written by using a code scanner. The former needs to be started to DOS for manual writing, which wastes time and labor cost; the latter is costly.
Disclosure of Invention
The technical problem to be solved by the invention is to provide a method for updating media access control addresses based on a serial port, which can effectively reduce hardware cost and improve production efficiency.
In order to solve the technical problem, the invention provides a method for updating a media access control address based on a serial port, which comprises the following steps:
(1) The control platform is connected with the mainboard through a serial port line;
(2) The firmware of the mainboard is configured with a corresponding serial port;
(3) And the control platform opens the updating software, responds to the firmware request of the mainboard through the serial port and automatically updates the MAC address.
Preferably, in the step (2), the configuration of the corresponding serial port by the firmware specifically includes:
(21) Starting up to a designated program, initializing a serial port Boot to an UpDateMAC function, sending a BYOMS instruction to the control platform through the serial port, and requesting to write an MAC address;
(22) After the mainboard receives the MAC address through the serial port, the MAC address is stored in a module FV in firmware appointed by the firmware, and the firmware sends an ending instruction through the serial port;
(23) starting up the computer next time, calling a designated program UpDateMAC by firmware, reading AN L AN PCI configuration Space, acquiring AN MAC IOBase, and acquiring the first six BYTE values in the IO Space through the IOBase;
(24) and judging whether the six values are full FF or full 00, if so, calling a program specified by the LAN to update the MAC address, and if not, directly returning without updating.
Preferably, in the step (3), the control platform receives a command sent by the serial port, and judges whether the command is a BYMS; if the serial port is BYMS, capturing MAC addresses stored on the computer, sequentially arranging the MAC addresses in a Buffer, and sending a first group of MAC addresses to the serial port; if the command is BOME, the sending is finished, the Buffer pointer jumps to the next group of MAC addresses, and the command sent by the serial port is waited to be received.
The invention has the beneficial effects that: the invention can effectively reduce hardware cost, improve production efficiency, save startup time and reduce labor cost.

Detailed Description
As shown in fig. 1 and 2, a method for updating a media access control address based on a serial port includes the following steps:
(1) The control platform is connected with the mainboard through a serial port line;
(2) The firmware of the mainboard is configured with a corresponding serial port;
(3) And the control platform opens the updating software, responds to the firmware request of the mainboard through the serial port and automatically updates the MAC address.
The mainboard sends a request command, the control platform receives the command and sends the MAC to the mainboard. After the mainboard receives the MAC, the content is stored in FV.
In the step (2), the configuration of the corresponding serial port by the firmware specifically comprises:
(21) Starting up to a designated program, initializing a serial port Boot to an UpDateMAC function, sending a BYOMS instruction to the control platform through the serial port, and requesting to write an MAC address;
(22) After the mainboard receives the MAC address through the serial port, the MAC address is stored in a module FV in firmware appointed by the firmware, and the firmware sends an ending instruction through the serial port;
(23) starting up the computer next time, calling a designated program UpDateMAC by firmware, reading AN L AN PCI configuration Space, acquiring AN MAC IOBase, and acquiring the first six BYTE values in the IO Space through the IOBase;
(24) and judging whether the six values are full FF or full 00, if so, calling a program specified by the LAN to update the MAC address, and if not, directly returning without updating.
In the step (3), the control platform receives a command sent by the serial port and judges whether the command is a BYMS; if the serial port is BYMS, capturing MAC addresses stored on the computer, sequentially arranging the MAC addresses in a Buffer, and sending a first group of MAC addresses to the serial port; if the command is BOME, the sending is finished, the Buffer pointer jumps to the next group of MAC addresses, and the command sent by the serial port is waited to be received.
The invention saves hardware cost, saves startup time, improves production efficiency and reduces labor cost.
While the invention has been shown and described with respect to the preferred embodiments, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the invention as defined in the following claims.
Claims (2)
1. A method for updating media access control address based on serial port is characterized by comprising the following steps:
