Patent ID: 7103736

Claim:
A system comprising: a nonvolatile memory having locations for the storage of first information; an external memory having locations for the storage of revised information to use as a replacement for at least some of the first information stored in the nonvolatile memory; a cache memory having addressable storage locations wherein the revised information can be stored, and having a designator to preclude replacement of the revised information stored in at least one of the addressable storage locations; and a start-up program executable by a processor for executing a series of instructions to determine whether there are any locations in the nonvolatile memory at which the first information stored is to be replaced with the revised information, and if the start-up program determines that there are such locations, causing the retrieval of the revised information and its storage into the cache memory, whereby the revised information to the first information stored in the nonvolatile memory can be made available to a system without modification of the nonvolatile memory.
