Common Hardware Reference Platform (CHRP) is a standardsystem architecture forPowerPC-based computer systems published jointly byIBM andApple in 1995. Like its predecessorPReP, it was conceptualized as a design to allow various operating systems to run on an industry standard hardware platform, and specified the use ofOpen Firmware andRTAS for machine abstraction purposes.
UnlikePReP, CHRP incorporated elements of thePower Macintosh architecture and was intended to support theclassic Mac OS andNetWare, in addition to the four operating systems that had been ported to PReP at the time (Windows NT,OS/2,Solaris, andAIX).
CHRP did not receive industry-wide adoption, however. The only systems to ship with actual CHRP hardware are certain members of IBM'sRS/6000 series runningAIX, and small amount of Motorola PowerStack workstations.[1]
Apple had planned to support CHRP onMac OS 8, and expectedMacintosh clone manufacturers to adopt it for their future hardware. However, after their acquisition ofNeXT and appointment ofSteve Jobs as acting CEO, Apple began to phase out the clone program, and decided against licensing any CHRP-based hardware.[2][3][4]
Power.org has a newPower Architecture Platform Reference (PAPR) that provides the foundation for development ofPower ISA-based computers running the Linux operating system. The PAPR was released fourth quarter of 2006.
