Abstract

A system of managing a plurality of peripheral interfaces in an IPMI architecture to communicate with a plurality of peripheral controllers is provided. The system comprises a memory address table, a firmware module for reading the memory address table to acquire an initial address corresponding to the respective peripheral interface and add an offset address to the initial address to generate an information structure, a protocol unit for converting each information structure to comply with a specific device protocol, a memory unit coupled to the memory address table, which is accessible according to the information structure with specific device protocol, to store/acquire a corresponding peripheral controller information, and a driver table coupled to the firmware module, having a plurality of peripheral controller drivers, corresponding to the respective peripheral controllers, each which are accessed by the firmware module in accordance with a specific peripheral controller information. At least one of the peripheral controllers is initialized according to the corresponding peripheral controller driver.
