Abstract: An apparatus to implement an IP independent firmware load is disclosed. The apparatus includes a plurality of agents, a plurality of agents, at least one agent including a memory to store firmware to be executed by the agent to perform a function associated with the agent and a register to store enumeration data for the firmware load mechanism of the IP, and a processor to initiate an enumeration process to read the enumeration data from the register of the at least one agent, make a decision based on that data to retrieve a firmware module from a storage device, verify the firmware module, and load the firmware module into the memory of the at least one agent.
