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.
