It is the Run-Time Abstraction Services which provide functions
to insulate operating systems from having to know about and manipulating
a number devices. It is a interface between hardware and software.
For example, RTAS provide functions for reading and writing PCI configuration,
shutdown, reboot, get time, managing power, ... of the CHRP computer.
