Run-Time Abstraction Services (RTAS)

Certain hardware devices differ from machine to machine, but provide similar functions. RTAS provides such hardware-specific functions, including functions for accessing the real-time clock, nonvolatile RAM (NVRAM), restart, shutdown, and PCI configuration cycles. RTAS is not available to clients other than the Mac OS.
