Abstract
Abstract The invention is a system, a method of operating the system and a method of customizing a processing system to operate with different input/output (I/O) systems. A system in accordance with the invention includes a processor, an I/O system coupled to the processor and system firmware, including a plurality of parts which each operate to perform system firmware functions required for and customized to only one of a plurality of different I/O systems which are operational when coupled to the processor, and a storage coupled to the processor, for storing identifying information which, when read, causes only one of the parts of the system firmware to be executed by the processor to perform the system firmware function necessary to operate the one of the different I/O systems identified by the identifying information.
