Abstract
A method and apparatus for initiating secure operations in a microprocessor system is described. In one embodiment, one initiating logical processor initiates the process by halting the execution of the other logical processors, and then loading initialization and secure virtual machine monitor software into memory. The initiating processor then loads the initialization software into secure memory for authentication and execution. The initialization software then authenticates and registers the secure virtual machine monitor software prior to secure system operations.
