Abstract: An example computing device including a processor, a first non-volatile memory to store a first basic input/output system (BIOS) image, a second non- volatile memory, and a controller. The controller Is to receive encrypted location and size information of the first BIOS image from the processor, verify the received encrypted location and size information of the first BIOS image, verify a signature of the first BIOS image in the first non-volatile memory, control a backup process of the first BIOS image to the second non-volatile memory, verify the signature of the backed up first BIOS image in the second non-volatile memory, and in response to a successful verification of the signature, send a message to the processor to cause the processor to perform a boot process using the first BIOS image from the first non-volatile memory.
