subarchitectures are supported.

In &debian-gnu; &release; sono supportate solo le sottoarchitetture PMac
(Power-Macintosh o PowerMac) e PreP.

<!--
There are four major supported <emphasis>&architecture;</emphasis>
subarchitectures: PMac (Power-Macintosh or PowerMac), PReP, APUS (Amiga
Power-UP System), and CHRP machines. Each subarchitecture has its own boot
methods. In addition, there are four different kernel flavours,
supporting different CPU variants.

Esistono quattro sottoarchitetture principali di
<emphasis>&architecture;</emphasis>: PMac (Power-Macintosh o PowerMac),
PReP, APUS (Amiga Power-UP System) e CHRP. Ciascuna sottoarchitettura ha
il proprio sistema di avvio ed esistono quattro varianti del kernel che
supportano i diversi tipi di CPU.

Ports to other <emphasis>&architecture;</emphasis> architectures, such
as the Be-Box and MBX architecture, are underway but not yet supported
by &debian;. We may have a 64-bit port in the future.

I port su altre architetture <emphasis>&architecture;</emphasis>, come
Be-Box e MBX sono in corso ma ancora non supportati da &debian;. In futuro
si potrebbe avere anche un port a 64&nbsp;bit.

Most systems use this kernel flavour, which supports the PowerPC 601,
603, 604, 740, 750, and 7400 processors. All Apple PowerMac machines
up to and including the one marketed as G4 use one of these processors.

La maggior parte dei sistemi usano questa variante del kernel che supporta
i processori PowerPC 601, 603, 604, 740 e 7400. Tutte le macchine Apple

<para>

<!--
Apple (and briefly a few other manufacturers &mdash; Power Computing, for
example) made a series of Macintosh computers based on the PowerPC
processor. For purposes of architecture support, they are categorized
as NuBus (not supported by &debian;), OldWorld, and NewWorld.
-->

Apple (e pochi altri costruttori, per esempio Power Computing) ha realizzato
una serie di computer Macintosh basata sul processore PowerPC. Dal punto
di vista delle architetture supportate queste macchine si dividono in
NuBus (non supportata da &debian;), OldWorld e NewWorld.

</para><para>

<!--
OldWorld systems are most Power Macintoshes with a floppy drive and a
PCI bus. Most 603, 603e, 604, and 604e based Power Macintoshes are
OldWorld machines. Those pre-iMac PowerPC models from Apple use a 
four digit naming scheme, except for the beige colored G3 systems, which 
are also OldWorld.
-->

I sistemi OldWorld sono la maggior parte dei Power Macintosh con un lettore
per dischetti e bus PCI. I Power Macintosh basati su 603, 603e, 604 e 604e
sono macchine OldWolrd. Gli Apple precedenti all'iMac PowerPC che hanno come
nome del modello un numero di 4 cifre, eccetto i sistemi G3 di colore beige,
sono degli OldWorld.

</para><para>

<!--
The so called NewWorld PowerMacs are any PowerMacs in translucent
colored plastic cases and later models. That includes all iMacs, iBooks,
G4 systems, blue colored G3 systems, and most PowerBooks manufactured in and
after 1999. The NewWorld PowerMacs are also known for using the <quote>ROM in
RAM</quote> system for MacOS, and were manufactured from mid-1998 onwards.
-->

I così detti PowerMac NewWorld sono tutti i PowerMac con il case in plastica
colorata translucida e i modelli successivi. Questi includono tutti gli iMac,
gli iBooks, i sistemi G4, i sistemi G3 di colore blu e la maggior parte dei
PowerBook costruiti dal 1999. I PowerMac NewWorld fabbricati a partire dalla
metà del 1998 sono conosciuti per l'uso del sistema <quote>ROM in RAM</quote>
per MacOS.
