Host Firmware is an integral ingredient of platforms at Intel. From the early days of proprietary BIOS in the 1980’s and 1990’s, to the world of standards in the 2000’s, to the post-PC world of the last few years, the nature of firmware has changed. This talk will discuss current trends in standards such as UEFI and associated EDKII firmware, other communities like coreboot, and common denominators like the Intel® Firmware Support Package. For the enterprise, open-source server host firmware and the Open Compute Project (OCP) Open System Firmware (OSF) efforts will also be described, including the recent publication of Min Platform. The talk will also touch on emerging solutions, challenges and market opportunities for more seamless enablement of Intel Architecture.
