Originally, the hardware architecture was so closely tied to the Mac OS operating system that it was impossible to boot an alternative operating system. The most common workaround, is to boot into Mac OS and then to hand over control to a Mac OS-based bootloader application. Used even by Apple for A/UX and MkLinux, this technique is no longer necessary since the introduction of Open Firmware-based PCI Macs, though it was formerly used for convenience on many Old World ROM systems due to bugs in the firmware implementation.[citation needed] Now, Mac hardware boots directly from Open Firmware in most PowerPC-based Macs or EFI in all Intel-based Macs.
Where does Mac harware boot directly to in most PowerPC-based Macs?
A: Open Firmware

Jefferson's concept of "separation of church and state" first became a part of Establishment Clause jurisprudence in Reynolds v. U.S., 98 U.S. 145 (1878). In that case, the court examined the history of religious liberty in the US, determining that while the constitution guarantees religious freedom, "The word 'religion' is not defined in the Constitution. We must go elsewhere, therefore, to ascertain its meaning, and nowhere more appropriately, we think, than to the history of the times in the midst of which the provision was adopted." The court found that the leaders in advocating and formulating the constitutional guarantee of religious liberty were James Madison and Thomas Jefferson. Quoting the "separation" paragraph from Jefferson's letter to the Danbury Baptists, the court concluded that, "coming as this does from an acknowledged leader of the advocates of the measure, it may be accepted almost as an authoritative declaration of the scope and effect of the amendment thus secured."
What does the constitution guarantee when it comes to religion?
A:
freedom
