coreboot* is an open source firmware project, describing a phase-based initialization infrastructure for Intel® architecture and other processor architectures. The coreboot platform initializes system hardware then launches a payload, which loads the operating system or other system applications.

Intel architecture platforms using coreboot are commonly enabled using the Intel® Firmware Support Package (Intel® FSP). Intel FSP provides silicon initialization ingredients for an open source framework.

Product and Performance Information


Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
