Old World ROM

Old World ROM computers are the Macintosh (Mac) models that use a Macintosh Toolbox read-only memory (ROM) chip, usually in a socket (but soldered to the motherboard in some models). All Macs prior to the iMac, the iBook, the Blue and White Power Mac G3 and the Bronze Keyboard PowerBook G3 use Old World ROM, while the iMac, iBook, Blue and White G3, and Bronze Keyboard PowerBook G3, as well as all subsequent models until the introduction of the Intel-based EFI Models, are New World ROM machines. In particular, the Beige Power Mac G3 and all other beige and platinum-colored Power Macs are Old World ROM machines. In common use, the "Old World" designation usually applies to the early generations of PCI-based "beige" Power Macs (and sometimes the very first NuBus-equipped models), but not the older Motorola 68000-based Macs; however, the Toolbox runs the same way on all three types of machines.

Details

PCI Power Macs with an Old World ROM contain an Open Firmware implementation, and a copy of the Macintosh Toolbox as an Open Firmware device. These machines are set to boot from this device by default, thus starting the normal Macintosh startup procedure. This can be changed, just as on New World ROM Macs, but with limitations placed on what devices and formats can be used; on these machines, particularly the early machines like the Power Macintosh 9500, the Open Firmware implementation was just enough to enumerate PCI devices and load the Toolbox ROM, and these Open Firmware revisions have several bugs which must be worked around by boot loaders or nvramrc patches. The Open Firmware environment can be entered by holding the key combination ⌘ Cmd+⌥ Option+O+F while booting.

Old World

The Old World consists of Africa, Europe, and Asia, regarded collectively as the part of the world known to Europeans before contact with the Americas. It is used in the context of, and contrast with, the New World (Americas).

Etymology

In the context of archaeology and world history, the term "Old World" includes those parts of the world which were in (indirect) cultural contact from the Bronze Age onwards, resulting in the parallel development of the early civilizations, mostly in the temperate zone between roughly the 45th and 25th parallels, in the area of the Mediterranean, Mesopotamia, Persian plateau, India and China.

These regions were connected via the Silk Road trade route, and they have a pronounced Iron Age period following the Bronze Age. In cultural terms, the Iron Age was accompanied by the so-called Axial Age, referring to cultural, philosophical and religious developments eventually leading to the emergence of the historical Western (Hellenism, "classical"), Eastern (Zoroastrian and Abrahamic) and Far Eastern (Hinduism, Buddhism, Confucianism, Taoism) cultural spheres.

Old World wine

Old World wine refers primarily to wine made in Europe but can also include other regions of the Mediterranean basin with long histories of winemaking such as North Africa and the Near East. The phrase is often used in contrast to "New World wine" which refers primarily to wines from New World wine regions such as the United States, Australia, South America and South Africa. The term "Old World wine" does not refer to a homogeneous style with "Old World wine regions" like Austria, France, Germany, Italy, Portugal, Romania and Spain each making vastly different styles of wine even within their own borders. Rather, the term is used to describe general differences in viticulture and winemaking philosophies between the Old World regions where tradition and the role of terroir lead versus the New World where science and the role of the winemaker are more often emphasized. In recent times, the globalization of wine and advent of flying winemakers have lessened the distinction between the two terms with winemakers in one region being able to produce wines that can display the traits of the other region—i.e. an "Old World style" wine being produced in a New World wine region like California or Chile and vice versa.
