Abstract: An apparatus to implement an IP independent secure firmware load into an IP agent without a ROM to establish hardware root of trust is disclosed. The apparatus includes a plurality of agents, at least one agent including an isolated memory region accessible only to a trusted entity of the at least one agent and a main memory, and a processor to allocate a section of the isolated memory region of the at least one agent, verify a first stage firmware module, the first stage firmware module comprising instructions to enable the at least one agent to load and verify a second stage firmware module, place the first stage firmware module into memory of the at least one agent without a ROM to establish the hardware root of trust
