Abstract
In one embodiment, the present invention includes a method for executing a first code portion of a pre-boot environment from a first non-volatile memory, authenticating a trusted hypervisor in the first non-volatile memory using the first code portion, executing the trusted hypervisor if the trusted hypervisor is authenticated, and authenticating a basic input/output system (BIOS) present in a second non-volatile memory with the trusted hypervisor and transferring control from the trusted hypervisor to the BIOS if the BIOS is authenticated. Other embodiments are described and claimed.
