Abstract: A computing system is configured to securely boot different operating systems. The computing system includes one or more processors, a first memory device storing a first firmware element for booting a first operating system, a second memory device storing a second firmware element for booting a second operating system, a first security module configured to provide authentication for booting the first operating system, and a second security module configured to provide authentication for booting the second operating system. The computing system is configured such that, when the first security module is connected to the one or more processors, either the first operating system or the second operating system is selected for booting based on a selection signal, and when the first security module is not connected to the one or more processors, the second operating system is selected for booting.

Abstract: One embodiment of the present invention provides a system for directing airflow through a computing device. This system comprises an airflow baffle, which includes a set of signal pins and a circuit. The airflow baffle is configured to direct airflow through the computing device, and the set of signal pins are configured to interface the airflow baffle with the computing device. Moreover, the circuit in the airflow baffle is coupled to the set of signal pins, and is configured to use the signal pins to notify the computing device that the airflow baffle is installed in the computing device.
