The application discloses a decoupling method, device, program product, server and storage medium, and relates to the field of servers. In view of the problem that the close coupling between a BMC and a BIOS causes the firmware versions of both to have to be kept in synchronization at all times, a decoupling method is provided, which introduces semantic hash values to replace field names to perform accurate matching of fields.
