Abstract
Approaches for customizing a unified extensible firmware interface (UEFI) compatible firmware component to support multiple hardware components. The UEFI compatible firmware component may be implemented by linking one or more executive drivers created in an executive module of the firmware component. The executive drivers, instead of platform drivers, are executed by UEFI dispatchers. The platform module, rather than being a collection of drivers, functions as a platform library that links to the executive drivers. One or more programs for providing one or more library functions to the one or more executive drivers are also linked into the firmware component. Call outs to board library functions provided by a board module are implemented in the executive drivers, instead of drivers of the platform module. The board library functions replace the one or more library functions provided to the executive drivers and reflect a change in a customer reference board (CRB).
