Common Hardware Reference Platform (CHRP) is a standard system architecture for PowerPC-based computer systems published jointly by IBM and Apple in 1995. Like its predecessor PReP, it was conceptualized as a design to allow various operating systems to run on an industry standard hardware platform, and specified the use of Open Firmware and RTAS for machine abstraction purposes.
