Detailed Description
The core of the application is to provide a BIOS option configuration method, a BIOS option configuration device, a server and a computer readable storage medium, and option configuration data is verified through a verification code when a 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.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in 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 obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In the related art, during the actual operation and maintenance operation of the server, the BIOS option of the server needs to be remotely configured. Specifically, an ipmi command is sent out-of-band to the BMC, and then the BIOS reads the stored data from the BMC to complete the option setting operation. However, data problems are easily caused in the process of reading data from the BMC by the BIOS, for example, if the data is tampered, the security of the BIOS option is directly affected, and the reliability of the BIOS is reduced.
Therefore, the application provides a BIOS option configuration method, which is characterized in that option configuration data is verified through a verification code when a BIOS is started, so that the option configuration data is verified, errors of the option configuration data are avoided, and the safety and reliability of the option configuration data are improved.
The following describes a BIOS option configuration method provided in the present application, by way of an embodiment.
Referring to fig. 1, fig. 1 is a flowchart illustrating a BIOS option configuration method according to an embodiment of the present disclosure.
In this embodiment, the method may include:
s101, the BMC receives option configuration data and a check code;
as can be seen, in this step, the BMC receives the option configuration data and the corresponding check code.
It is conceivable that the present embodiment further includes a step of sending the option configuration data and the check code to the BMC. The BMC may send data to the local server, send data to the BMC by another server in a remote manner, and send data to the BMC by another computing device. It can be seen that, in this embodiment, the manner of sending data to the BMC is not unique, and is not specifically limited herein.
And, only option configuration data is transmitted to the BMC in the related art. Therefore, 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, damage may be done to the BIOS. Therefore, in order to avoid the modified option configuration data from failing, the check code corresponding to the option configuration data needs to be sent to the BMC.
S102, when the BIOS is started, the BMC checks option configuration data according to the check code;
on the basis of S101, this step aims at checking, by the BMC, the option configuration data according to the check 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 check processes may be performed according to different check codes, so as to implement corresponding check operations, which is not specifically limited herein.
S103, when the verification is passed, sending the option configuration data to the BIOS so that the BIOS can set according to the option configuration data;
on the basis of S102, this step is intended to send 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 as it is. Therefore, the option configuration data is directly sent to the BIOS so as to carry out corresponding setting operation on the BIOS.
The operation of setting according to the option configuration data may adopt 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 acquiring the option configuration data from the BMC in the BIOS, transfers the option configuration data from the BMC to the BIOS.
And 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 is erroneous. Therefore, the option configuration data is not sent to the BMC at this time. But the option configuration data is repaired 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 out the backed-up option configuration data as the repaired configuration data, or to adopt a scheme of combining the two.
As can be seen, in order to provide a further way for configuring 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 to say, in this alternative, the option configuration data may also be backed up, so as to avoid the option configuration data being modified in the BMC, and further ensure the reliability that the option configuration data can be repaired.
On this basis, the step can comprise:
step 1, judging whether the standby configuration data is correct or not according to the check code when the check code does not pass; if yes, executing the step 2, otherwise, executing the step 3;
step 2, sending the standby configuration data to the BIOS;
and 3, carrying out 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 the present alternative is mainly illustrative of how to recover option configuration data. In this alternative, when the check fails, whether the standby configuration data is correct is determined according to the check code. I.e. to determine whether the backed up option configuration data is correct. If yes, sending the standby configuration data to the BIOS; if not, carrying out verification calculation according to the verification code to obtain repaired configuration data, and sending the repaired configuration data to the BIOS. The check calculation can be performed by selecting different calculation modes according to different check codes.
Wherein, the verification method in the previous step may include:
and carrying out check calculation on the check code according to a parity check algorithm to obtain the repaired configuration data.
The parity check algorithm may be any one of parity check algorithms provided in the prior art, and is not specifically limited herein.
Wherein, the verification method in the previous step may include:
and carrying out 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 one of cyclic redundancy check algorithms provided in the prior art, and is not specifically limited herein.
In summary, in the embodiment, the option configuration data is verified through the check code when the BIOS is started, so that the option configuration data is verified, an error in the option configuration data is avoided, and the security and reliability of the option configuration data are improved.
The BIOS option configuration method provided in the present application is further described below by an embodiment of a specific scenario.
In this embodiment, when the command for configuring the BIOS option is sent remotely from the out-of-band, the check code is also sent to the BMC at the same time, after receiving the data packet, the BMC copies one copy of the data and stores the copy of the data in an EEPROM (Electrically Erasable Programmable read only memory), when the BIOS is started, the BMC reads the configuration option data from the BMC, first checks valid data and compares the valid data with the check code, if the check code is different, the backup data is checked continuously, if the backup check passes, the backup data is updated to the main data, if the backup data check also fails, data bits of the main data and the backup data are compared in sequence, and if different data bits exist, the stored check code is compared and restored to a correct value, thereby achieving the purpose of data error correction.
As can be seen, the steps of this embodiment may include:
step 1, remotely sending a BIOS configuration option command and a check code to a BMC;
step 2, the BMC backs up and stores the data into the EEPROM;
step 3, starting the BIOS to read the configuration option data from the BMC;
step 4, the BMC checks the main data and the check code, and returns the main data and the check code to the BIOS if the main data and the check code pass the check;
step 5, if the verification fails, the BMC reads the backup data and verifies the backup data, and if the verification succeeds, the BMC copies the main data and returns the main data to the BIOS;
and 6, if the backup data is failed to be verified, sequentially comparing the main data bits and the standby data bits, if the data bits are different, confirming correct data through a verification code and correcting, and returning the corrected data to the BIOS.
Therefore, the option configuration data can be verified through the verification code when the BIOS is started, so that the option configuration data can be verified, errors in the option configuration data are avoided, and the security and reliability of the option configuration data are improved.
