The principle of judging whether the mainboard information in the SMBIOS data structure table is valid mainboard information or invalid information is that the mainboard information can be analyzed into visible characters for users to look up under the system. If the invisible character code exists in the mainboard information, the mainboard information is invalid information. In addition, the serial number and the asset number information must be updated when the product leaves the factory, the serial number and the asset number information corresponding to each product are unique and cannot be equal to data predefined by the BIOS or the BMC, and if the data is equal to character data predefined by the BIOS or the BMC, the motherboard information is also invalid information.
After the initialization of the motherboard information in the SMBIOS data structure table is completed, based on the judgment principle of the validity of the motherboard information, the validity judgment and the backup and update of the motherboard information of this embodiment include the following several situations:

When the mainboard information data in the SMBIOS data structure table is processed, the command program is sent by calling the BMC according to the predefined format configuration, and the mainboard information data is sent to the BMC, so that the mainboard information data in the FRU is updated.
And S242, acquiring FRU synchronization mark data and judging whether a synchronization mark is set.
S252, according to the judgment result, if the synchronous mark is set, the operation of the whole program is ended; if the synchronous mark is not set, the operation of the whole program is finished after the synchronous mark is set.

S351, according to the judgment result, if the synchronous mark is set, the operation of the whole program is ended; if the synchronous mark is not set, the operation of the whole program is finished after the synchronous mark is set.
According to the steps, the main board information in the SMBIOS data structure table and the main board information in the FRU are both effective main board information through effectiveness judgment, and the main board information of the SMBIOS data structure table is consistent with the main board information of the FRU, so mutual synchronization and updating of the effective main board information between the SMBIOS data structure table and the FRU are not needed.
