Description
Technical field
The present invention relates to computer production technical field, especially a kind of side that general unique identifier is updated based on serial ports
Method.
Background technology
With the development of technology, the correlation technique of computer is being constantly updated, and production technology is being improved constantly.But at present in work
When producing motherboard in factory, the general unique identifier (UUID) above every a piece of motherboard still will be to hand below DOS
Dynamic is write with a brush dipped in Chinese ink with autoexec, and a little bigger manufacturer is also intended to start shooting to below DOS to be write with a brush dipped in Chinese ink with barcode scanning machine.Use batch processing
To write with a brush dipped in Chinese ink, to start shooting to DOS, also to write, lose time and manpower manually；Write with a brush dipped in Chinese ink with barcode scanning machine, with high costs, efficiency is low
Under.
The content of the invention
The technical problems to be solved by the invention are that there is provided a kind of side that general unique identifier is updated based on serial ports
Method, can effectively reduce hardware cost, improve production efficiency.
In order to solve the above technical problems, the present invention provides a kind of method that general unique identifier is updated based on serial ports, bag
Include following steps：
(1) control platform is connected with motherboard by Serial Port Line；
(2) the corresponding serial ports of the firmware configuration of motherboard；
(3) control platform, which is opened, updates software, and the firmware requests of motherboard are responded by serial ports, automatically updates general unique
Identification code UUID.
It is preferred that, in step (2), the corresponding serial ports of firmware configuration is specially：
(21) designated program is arrived in start, has initialized serial ports Boot to UpDateUUID functions, BYOUS is sent by serial ports
Instruct to control platform, request write-in UUID；
(22) motherboard is received after UUID by serial ports, after the completion of UUID refreshes, and what UUID was stored in that firmware specifies consolidates
In a module FV in part, firmware sends END instruction by serial ports；
(23) machine is established by cable on next time, firmware calls designated program UpDateUUID by updating SMBIOS table UUID
It is written to inside TYPE1；
(24) if 16 Byte positions are full 00 or full FF behind Offset 08h, by updating SMBIOS table
UUID in FV is updated into TYPE1；If it is not, then without updating, directly returning.
It is preferred that, in step (3), control platform receives the order that serial ports is sent, and judges whether order is BYOUS；Such as
Fruit is BYOUS, then captures and be arranged in order inside UUID to the Buffer that computer is stored above, and send out first group of UUID toward serial ports；
If BYOUE, then terminate to send, Buffer pointers jump to next group of UUID address, the life for waiting serial ports to be received to send
Order.
Beneficial effects of the present invention are：The present invention can effectively reduce hardware cost, save the available machine time, improve production
Efficiency, reduces labour cost.
Brief description of the drawings

Fig. 2 is the system structure diagram of the present invention.
Fig. 3 is the TYPE1 structural representations in the SMBIOS specifications of the present invention.
Embodiment
As illustrated in fig. 1 and 2, a kind of method that general unique identifier is updated based on serial ports, is comprised the following steps：
(1) control platform is connected with motherboard by Serial Port Line；
(2) the corresponding serial ports of the firmware configuration of motherboard；
(3) control platform, which is opened, updates software, and the firmware requests of motherboard are responded by serial ports, automatically updates general unique
Identification code UUID.
Motherboard sends request command, and control platform receives order, sends UUID to motherboard.Motherboard receives UUID
Content is present in FV afterwards.
As shown in figure 3, in step (2), the corresponding serial ports of firmware configuration is specially：
(21) designated program is arrived in start, has initialized serial ports Boot to UpDateUUID functions, BYOUS is sent by serial ports
Instruct to control platform, request write-in UUID；
(22) motherboard is received after UUID by serial ports, after the completion of UUID refreshes, and what UUID was stored in that firmware specifies consolidates
In a module FV in part, firmware sends END instruction by serial ports；
(23) machine is established by cable on next time, firmware calls designated program UpDateUUID by updating SMBIOS table,
SMBIOS table are specially System Management BIOS systems management BIOS, are by system firmware transmission management letter
A total of 127 Type inside the standard of breath, SMBIOS table, UUID are written to inside TYPE1；
(24) if 16 Byte positions are full 00 or full FF behind Offset 08h, by updating SMBIOS table
UUID in FV is updated into TYPE1；If it is not, then without updating, directly returning.
In step (3), control platform receives the order that serial ports is sent, and judges whether order is BYOUS；If
BYOUS, then capture and be arranged in order inside UUID to the Buffer that computer is stored above, and send out first group of UUID toward serial ports；If
It is BYOUE, then terminates to send, Buffer pointers jump to next group of UUID address, the order for waiting serial ports to be received to send.
The present invention saves hardware cost, saves the available machine time, improves production efficiency, reduces labour cost.
Although the present invention is illustrated and described with regard to preferred embodiment, it is understood by those skilled in the art that
Without departing from scope defined by the claims of the present invention, variations and modifications can be carried out to the present invention.
Claims (3)
