Technical Field
The invention belongs to the technical field of BIOS firmware updating, and particularly relates to a method and a device for realizing BIOS upgrading and downgrading configuration option reservation.
Background
With the continuous popularization and development of server technology, the performance, the function and the usability of the server are continuously enhanced, BIOS Setup configuration options in the server are more and more, and different clients can configure different option combinations according to the service requirements of themselves, but the following problems are often faced in the setting process: 1. after the setting of a plurality of node options on the line or the production line is completed, the BIOS needs to update and refresh the operation, and the operation of the original option setting is needed, so that the manpower is wasted and the configuration efficiency is affected. 2. After the configuration is completed, it is necessary to check whether the setting state of the option is correct.
The retention of BIOS options is currently done by two schemes. The first is to use AFU tool to reserve BIOS option when in-band refreshing, wherein the scheme is that option variable is located in NVRAM of BIOS, refreshing of the area can be skipped according to refreshing instruction to realize reserving BIOS option, but when option layout of front and back versions of BIOS is changed, function of reserving parameter can not be realized, and whole BIOS area must be forcedly refreshed. The second is to reserve BIOS options based on the redfish technology, the scheme BMC stores option set json files generated after options are set, after BIOS updating is completed, BIOS synchronizes json files according to conditions of reserved parameter refreshing in the starting process, option variables in BIOS are updated, and reserving of BIOS options is achieved.
This is a deficiency of the prior art, and therefore, it is necessary to provide a method and apparatus for implementing BIOS promotion and degradation configuration option reservation in order to address the above-mentioned drawbacks of the prior art.

Further, the specific steps of step S2 are as follows:
s21, the user sends configuration options needing to be modified and modified data to the BMC through an IPMI write command;
and S22, the BMC stores configuration options and modification data which need to be modified into the first data structure body, and sets the flag bit of the first data structure body. The flag bit in the first data structure is used to indicate whether a modification to the BIOS configuration option is required.
Further, the specific steps of step S3 are as follows:
s31, after the BIOS is started, reading a flag bit from a first data structure body of the BMC through an IPMI read command, and judging whether the flag bit is set or not;
if yes, go to step S32;

The option combination structure and the temporary structure realize the butt joint of the BIOS and the data in the BMC.
Further, the specific steps of step S5 are as follows:
s51, judging whether in-band refreshing or out-of-band refreshing is carried out on the BIOS;
