Abstract:
An article of manufacture is provided for securing a region in a memory of a computer. According to one embodiment, the article of manufacture comprises a machine-accessible medium including data that, when accessed by a machine, causes the machine to: halt all but one of a plurality of processing elements in a computer, where the halted processing elements enter into a special halted state; load content into the region only after the halting of all but the one of the plurality of processing elements and the region is protected from access by the halted processing elements; place the non-halted processing element into a known privileged state; and cause the halted processing elements to exit the halted state after the non-halted processing element has been placed into the known privileged state.
