Abstract
An information handling system includes a first memory that stores a firmware image associated with the baseboard management controller. The baseboard management controller begins execution of a kernel, which in turn performs a boot operation of the information handling system. The baseboard management controller begins a file system initialization program. During the boot operation, the baseboard management controller performs a full read and cryptographic verification of the firmware image via a DM-Verity daemon of the file system initialization program. In response to the full read of the firmware image being completed, the baseboard management controller provides a flush command to the kernel via the DM-Verity daemon. The baseboard management controller flushes a cache buffer associated with the baseboard management controller via the kernel.
