Abstract
A method and apparatus for initializing a computer system, which includes a lockable nonvolatile memory coupled to a processor having maskable address lines and a cache, when a nonvolatile memory update is in process. When an update is in process, the nonvolatile memory is unlocked in response to the initialization event only if address line masking is disabled, and at least a portion of the processor cache is invalidated to ensure the processor will fetch the first instruction from the nonvolatile memory.
