1. A method for controlling access to storage loci in a registry, the method comprising the acts of:

  • receiving an attempt to access a first storage locus (“

    first-storage-locus access attempt”

    ) in a registry from a program module, a registry being an hierarchical common configuration data structure stored on a storage component of a computing system, where individual elements of the data structures are addressable for storing data therein or accessing data stored therein and the registry is separate from and not part of a Basic Input-Output System (BIOS) of the computing system;

    redirecting the first-storage-locus access attempt so that it, instead, accesses at least a second locus in the registry, wherein the redirecting act is carried out in such a manner that the program module is unaware that its access attempt is being redirected to the second locus;

    wherein;

    the first storage locus in the registry is reserved for configuration information (“

    config-info”

    ) for a first version of the program module;

    the second storage locus in the registry is reserved for config-info for a second version of the program module.
