Double-BIOS firmware synchronization method and system

The invention provides a double-BIOS firmware synchronization method and system, and the method employs a double-BIOS firmware synchronization design, and can automatically synchronize the firmware burnt on a main BIOS to a standby BIOS through a BMC after the main BIOS firmware is updated. When the main non-volatile storage medium fails to start, the standby main non-volatile storage medium can be automatically switched to start, and the previous latest configuration can be automatically applied; the maintenance cost of version and configuration synchronization when double BIOS firmware is used is reduced, errors easily caused by manual operation are avoided, and the technical problem that in the prior art, version information and configuration information of main and standby BIOS firmware are not synchronized is effectively solved. 本申请提供一种双BIOS固件同步方法和系统，采用双BIOS固件同步设计，在主BIOS固件被更新后，通过BMC可以自动将主BIOS上烧录的固件自动同步到备用BIOS；在利用主非易失性存储介质启动失败时，可以自动切换至备主非易失性存储介质进行启动，并能自动应用此前的最新配置；减少了使用双BIOS固件时版本和配置同步的维护成本，也避免了人为操作容易导致的错误，
