    摘要: Various embodiments are generally directed to authenticating a chain of components of boot software of a computing device. An apparatus comprises a processor circuit and storage storing an initial boot software component comprising instructions operative on the processor circuit to select a first set of boot software components of multiple sets of boot software components, each set of boot software components defines a pathway that branches from the initial boot software component and that rejoins at a latter boot software component; authenticate a first boot software component of the first set of boot software components; and execute a sequence of instructions of the first boot software component to authenticate a second boot software component of the first set of boot software components to form a chain of authentication through a first pathway defined by the first set of boot software components. Other embodiments are described and claimed herein.

    摘要: Technologies for improving platform initialization on a computing device include beginning initialization of a platform of the computing device using a basic input/output system (BIOS) of the computing device. A security co-processor driver module adds a security co-processor command to a command list when a security processor command is received from the BIOS module. The computing device establishes a periodic interrupt of the initialization of the platform to query the security co-processor regarding the availability of a response to a previously submitted security co-processor command, forward any responses received by the security co-processor driver module to the BIOS module, and submit the next security co-processor command in the command list to the security co-processor.

    摘要: A method, processor, and system are disclosed. In one embodiment method includes a first processor core among several processor cores entering into a system management mode. At least one of the other additional processor cores apart from the first processor core remain operational and do not enter the system management mode. Then, once in the system management mode, the first processor core responds to an inter-processor interrupt.

    摘要: A first video messaging service, running on top of an operating system in a data processing system, automatically presents a first video message. After using the first video messaging service to present the first video message, the data processing system automatically determines whether the first video messaging service has become nonfunctional. In response to determining that the first video messaging service has become nonfunctional, the data processing system automatically uses a backup video messaging service to present a second video message. The backup video messaging service operates in a boot environment. In one embodiment, the data processing system is configured to provide digital signage, the first video messaging service presents content for the digital signage when the operating system is operational, and the second video messaging service presents content for the digital signage when the operating system is nonfunctional. Other embodiments are described and claimed.
