Abstract
Example implementations relate to system and method of signing a boot information file by a manageability controller, and interlocking host computing system to signed boot information file. The boot information file may include a boot loader file and/or an OS kernel file of the host computing system. The manageability controller receives the boot information file from a processor of a computing device. Further, the manageability controller signs the boot information file with a hashed data of a unique identifier, to generate and communicate the signed boot information file to the processor. Later, the manageability controller updates a boot database stored in non-volatile random-access memory of a firmware engine of the host computing system with a thumbprint data of the signed boot information file to interlock the host computing system to the signed boot information file, in response to successful download of the signed boot information file by the processor.
