Embodiment Construction

[0018] Such as figure 1 and 2 As shown, a method for updating the UUID based on the serial port includes the following steps:

[0019] (1) The control platform and the motherboard are connected through a serial cable;

[0020] (2) The firmware of the motherboard configures the corresponding serial port;

[0021] (3) The control platform opens the update software, responds to the firmware request of the motherboard through the serial port, and automatically updates the universal unique identification code UUID.

[0022] The motherboard sends the request command, the control platform receives the command, and sends the UUID to the motherboard. After receiving the UUID, the motherboard stores the content in the FV.

[0023] Such as image 3 As shown, in step (2), the firmware configures the corresponding serial port as follows:

[0024] (21) Boot to the specified program, initialize the serial port Boot to the UpDateUUID function, send the BYOUS command to the control platf...

Abstract

The invention discloses a method for updating universal unique identification codes on the basis of serial ports. The method comprises the following steps of: (1) connecting a control platform and a mainboard through a serial port line; (2) configuring a corresponding serial port for firmware of the mainboard; and (3) opening updating software by the control platform, responding a firmware request of the mainboard through the serial port, and automatically updating a universal unique identification code UUID. The method disclosed by the invention has the beneficial effects of effectively reducing the hardware cost, saving the startup time, improving the production efficiency and reducing the labor cost.

Description

technical field [0001] The invention relates to the technical field of computer production, in particular to a method for updating a universal unique identification code based on a serial port. Background technique [0002] With the development of technology, computer-related technologies are constantly being updated, and the production process is constantly improving. But at present, when producing motherboards in the factory, the Universal Unique Identification Number (UUID) on each motherboard still needs to be flashed manually with a batch file under DOS. Larger manufacturers also need to boot into DOS. Use a code scanner to write. If you use batch processing to write, you need to boot to DOS and write manually, which is a waste of time and manpower; using a code scanner to write is expensive and inefficient. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for updating a universal unique identifica...
