For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
In the related art, in the actual operation and maintenance process of the server, the BIOS option of the server needs to be configured remotely. Specifically, the option setting operation is completed by sending an ipmi command to the BMC out of band, and then the BIOS reads the stored data from the BMC. However, in the process of reading data from the BMC by the BIOS, a data problem is easy to occur, for example, when the data is tampered, the security of the BIOS option is directly affected, and the reliability of the BIOS is reduced.
Therefore, the BIOS option configuration method is provided, and the option configuration data is verified through the verification code when the BIOS is started, so that verification of the option configuration data is realized, errors of the option configuration data are avoided, and the safety and reliability of the option configuration data are improved.
A BIOS option configuration method provided in the present application is described below by using an embodiment.
Referring to fig. 1, fig. 1 is a flowchart of a BIOS option configuration method according to an embodiment of the present application.
In this embodiment, the method may include:
s101, BMC receives option configuration data and check codes;
in this step, the BMC receives the option configuration data and the corresponding check code.
It is conceivable that the step of sending the option configuration data and the check code to the BMC is further included in this embodiment. The server may send data to the BMC locally, may send data to the BMC remotely by other servers, or may send data to the BMC by other computing devices. It should be noted that, in this embodiment, the manner of sending data to the BMC is not limited in detail herein.
Also, only option configuration data is transmitted to the BMC in the related art. Thus, when the BMC obtains the option configuration data, the BMC directly sends the option configuration data to the BIOS. However, if the option configuration data is modified at this time, the BIOS is damaged. Therefore, in order to avoid the failure of modification of the option configuration data, a check code corresponding to the option configuration data needs to be sent to the BMC.
S102, when the BIOS is started, the BMC checks the option configuration data according to the check code;
on the basis of S101, this step aims at verifying the option configuration data by the BMC according to the verification code when the BIOS is started. That is, whether the option configuration data is correct is determined according to the check code.
In this step, different verification processes may be performed according to different verification codes, so as to implement corresponding verification operations, which are not specifically limited herein.
S103, when the verification passes, the option configuration data is sent to the BIOS so that the BIOS can set according to the option configuration data;
on the basis of S102, this step aims at transmitting the option configuration data to the BIOS when the verification passes, so that the BIOS performs setting according to the option configuration data.
That is, the option configuration data at this time has no problem and can be used directly. Therefore, the option configuration data is directly sent to the BIOS so as to perform corresponding setting operation on the BIOS.
The operation of setting according to the option configuration data may be any BIOS setting operation provided in the prior art, which is not specifically limited herein.
The process of sending the option configuration data to the BIOS, that is, the process of obtaining the line selection configuration data from the BMC in the BIOS, is to transfer the option configuration data from the BMC to the BIOS.
S104, when the verification fails, repairing the option configuration data to obtain repaired configuration data, and sending the repaired configuration data to the BIOS.
On the basis of S102, this step aims to repair the option configuration data to obtain repaired configuration data when the verification fails, and send the repaired configuration data to the BIOS.
That is, it has been determined at this time that the option configuration data has an error. Therefore, this option configuration data is not sent to the BMC at this time. And repairing the option configuration data to obtain repaired configuration data.
The repair processing may be to encode and repair the option configuration data according to the check code to obtain the repaired configuration data, or to take the backed-up option configuration data out as the repaired configuration data, or to use a scheme of combining the two.
It can be seen that, in order to provide a further way to configure the option configuration data, this embodiment may further include:
and when the BMC receives the option configuration data, backing up the option configuration data to obtain standby configuration data.
That is, the option configuration data may be backed up in the present alternative, so as to avoid modification of the option configuration data in the BMC, and further ensure reliability that the option configuration data may be repaired.
On this basis, this step may include:
step 1, judging whether the standby configuration data is correct according to the check code when the check is failed; if yes, executing the step 2, and if not, executing the step 3;
step 2, sending the standby configuration data to the BIOS;
and step 3, performing verification calculation according to the verification code to obtain repaired configuration data, and sending the repaired configuration data to the BIOS.
It can be seen that this alternative is mainly to explain how to restore option configuration data. In the alternative scheme, when the verification fails, whether the standby configuration data is correct or not is judged according to the check code. I.e. to determine if the backed up option configuration data is correct. If yes, sending the standby configuration data to the BIOS; if not, checking and calculating according to the check code to obtain repaired configuration data, and sending the repaired configuration data to the BIOS. The verification calculation can be performed by selecting different calculation modes according to different verification codes.
The verification method in the previous step may include:
and performing check calculation on the check code according to the parity check algorithm to obtain the repaired configuration data.
The parity check algorithm may be any one of those provided in the prior art, and is not specifically limited herein.
The verification method in the previous step may include:
and performing check calculation on the check code according to a cyclic redundancy check algorithm to obtain repaired configuration data.
The cyclic redundancy check algorithm may be any cyclic redundancy check algorithm provided in the prior art, and is not specifically limited herein.
In summary, the present embodiment verifies the option configuration data through the check code when the BIOS is started, so as to verify the option configuration data, avoid the error of the option configuration data, and improve the security and reliability of the option configuration data.
The following further describes a BIOS option configuration method provided in the present application through an embodiment of a specific scenario.
In this embodiment, when the command for configuring the BIOS option is remotely sent from the out-of-band, the check code is also sent to the BMC at the same time, after the BMC receives the data packet, the data is copied into one copy and stored in the EEPROM (Electrically Erasable Programmable read only memory, live erasable programmable read only memory) at the same time, when the BIOS is started, the configuration option data is read from the BMC, the BMC checks the valid data first and compares with the check code, if the check code is different, the backup data is continuously checked, if the backup check is passed, the backup data is updated to the main data, if the backup data check is also failed, the data bits of the main data and the backup data are sequentially compared, and if the data bits are different, the stored check code is used to restore to the correct value, thereby achieving the purpose of data error correction.
It can be seen that the steps of this embodiment may include:
step 1, remotely sending a BIOS configuration option command and a check code to the BMC;
step 2, the BMC backs up the data and stores the data into the EEPROM;
step 3, BIOS starts to read configuration option data from BMC;
step 4, the BMC checks the main data and the check code, and if the check is passed, the BMC returns to the BIOS;
step 5, if the verification fails, the BMC reads the backup data and verifies, if the verification succeeds, the backup data is copied to the main data and returned to the BIOS;
and 6, if the backup data also fails to be checked, comparing the main data bit with the backup data bit in turn, if the data bit is different, confirming correct data through the check code and correcting, and returning the corrected data to the BIOS.
Therefore, the embodiment can verify the option configuration data through the check code when the BIOS is started, so that verification of the option configuration data is realized, errors of the option configuration data are avoided, and the safety and reliability of the option configuration data are improved.
