Example 1
As shown in fig. 1, the method for automatically updating the local serial number from the network when the BIOS is powered on in the factory mode includes the following steps:
1) on a factory production line, a machine station is brushed with a brand-new BIOS program, and is plugged with a network cable and started.
2) Because of the new BIOS, the serial number update flag is false (0), at which time the BIOS automatically enters the update state.
3) The update module is connected with a server of the factory, informs the information of the model, version and the like of the update module, and requests a serial number from the server.
4) The server inquires the database after receiving the information, allocates a unique serial number of the whole plant, and transmits the number back to the machine.
5) The server may not return the information in time due to the large access amount, etc., and the attempt is made 3 times, if none of the 3 times returns within the expected time, the machine is restarted, and the process is restarted from step 2.
6) After the machine station successfully receives the serial number, the number is recorded in a nonvolatile storage area of the machine station, and the serial number updating mark is recorded as true.
7) And restarting the machine, wherein the BIOS finds that the serial number update mark is not 0 or null, and knows that the serial number is written, so that the serial number is read from the nonvolatile storage area and is filled in an interface defined by the industry specification.
8) After the operating system is started, the application program reads the serial number, queries a company server, obtains the date of the computer leaving factory, calculates the warranty period and displays the warranty period for a user.
Example 2
The method for automatically updating the local serial number from the network when the BIOS is started in a factory mode comprises the following steps:
1) and (4) building a serial number server, opening a DHCP service, and waiting for a request of a client.
2) The BIOS applies for a section of non-volatile storage, which is generally to find a ROM area that is not used yet, because the characteristics of flash, where it is not used, generally has a value of 0xFF, this section of area is defaulted to have a value of 0xFF in its entirety.
3) The BIOS is flushed into the SPI ROM of the machine station, and the machine station is started.
4) The BIOS reads the first byte of the nonvolatile storage area in the step 2), finds that the first byte is not 0xFC, indicates that no serial number exists currently or the last serial number update fails, and starts to enter a serial number update mode this time. If the updating fails, all data in the area is erased, and the data block is restored to be all 0 xFF.
5) The BIOS loads the network driver and service so that the current network card can obtain an effective IP address and the IP address of the server.
6) The model of the BIOS has been pre-selected within the BIOS and is now sent to the server as a parameter. This request frame contains a fixed header tag (0 xAA), a command word (0 x 01), a data length, a BIOS model string, a fixed end tag (0 x 55), and a data checksum.
7) After receiving the message, the server looks up the table according to the BIOS model, finds the named prefix of the model and the current serial number, adds the named prefix and the current serial number to form a character string together with the prefix, and forms a sending frame similar to the client: header flag (0 xAA), command word (0 x 81), data length, sequence number string, fixed end (0 x 55), data checksum. This frame is sent to the client.
8) After the BIOS sends the request frame, it checks the arrival of the response frame every 200 milliseconds, waiting for a maximum of 3 seconds. If the response frame is not waited for within 3 seconds or the data structure is not correct, the request is retransmitted. If none of the 3 times is successful, restart from step 4).
9) The received response frame has no problem, from which the sequence number is extracted. The first byte of the non-volatile area is written as 0xFE, indicating that the sequence number string is to be written immediately. The serial number string is written in the nonvolatile area starting from the second byte. The first byte of the non-volatile area is written as 0xFC, indicating that the write is complete.
10) Sending a sequence number confirmation to the server, with a format similar to the request frame: header flag (0 xAA), command word (0 x 02), data length, sequence number string, fixed end (0 x 55), data checksum. To prevent the server from failing, this command is sent 3 times in a burst with a pause of 50 milliseconds in between.
11) The server marks the sequence number as used upon receipt. The server periodically recycles the sequence numbers that have been sent out but not acknowledged.
12) BIOS fills this sequence number into the serial number field of compact table type1 and re-issues this type.
13) And continuing to start, and ending the function.
