はじめに
Gentooハンドブックは、ドキュメントを一貫性のあるハンドブックに集約する取り組みの成果です. このハンドブックには、インターネットを用いたインストールするやりかたでのインストール手順や、GentooとPortageの操作方法が含まれています.

アーキテクチャ
Gentoo Linuxは様々なアーキテクチャで利用できます. しかし、アーキテクチャとは何でしょうか？

アーキテクチャとは、同じ命令群を理解できるCPU (プロセッサ) ファミリのことです. デスクトップの世界における最も有名な2つのアーキテクチャは、アーキテクチャとx86_64アーキテクチャ (Gentooではという表記を使います) です. しかし、他にも多くのアーキテクチャが存在します. 例えば、、 (PowerPCファミリ)、、…….

Gentooと同程度に汎用的なディストリビューションでは、多くのアーキテクチャをサポートしています. そのため、サポートされているアーキテクチャごとにGentooハンドブックが提供されていることにもお気づきでしょう. しかし、全てのユーザがその違いを認識しているわけではないので、ある種の混乱に繋がる可能性があります. システムの一部分としてのCPUの種類や名前 (i686とかIntel Core i7のような) のみを認識している人もいます. 下記にサポートされているアーキテクチャの簡単な説明と、Gentooで用いられる略語があります. しかし、自分のシステムのアーキテクチャを知らない大抵の人は、ほんんどの場合またはが関連します.

Viewing the Handbook
The list below gives a high-level overview of the architectures supported by various Gentoo Linux projects. It is important to choose the correct architecture before proceeding with the associated Installation section of a Handbook. Be sure to verify the CPU's architecture before moving onward.

A note for new Gentoo users: if the CPU is less than five years old and the manufacturer is either Intel or AMD, choosing the AMD64 Handbook is probably the correct route.


 * Alpha Handbook
 * The Alpha architecture is a 64-bit architecture developed by Digital Equipment Corporation (DEC). It is still in use by some mid-range and high-end servers, but the architecture is slowly being faded out. Variants include: ES40, AlphaPC, UP1000, and Noname.
 * Full sections: Installation – Working – Portage – Networking


 * AMD64 Handbook
 * AMD64 is a 64-bit architecture that is compatible with the architecture (and thus also known as ). It was first used by AMD (under the AMD64 name) and Intel (under the EM64T name) and is now the most prominent architecture for medium and high-end desktop PCs. It is also commonly found in the server segment. Variants include: AMD Athlon 64, Opteron, Sempron, Phenom, FX, and Ryzen along with Intel Pentium 4, Core2, Core i3, i5, i7, and some Atoms.

 * ARM Handbook
 * ARM is a 32-bit architecture that is a very popular in embedded and small systems. Sub-architectures range from ARMv1 to ARMv7 (Cortex) and are often found in smart phones, tablets, hand-held consoles, end-user GPS navigation systems, etc. Variants include: StrongARM and Cortex-M.
 * There is no ARM Handbook available at this time. Please see.


 * ARM64 Handbook
 * ARM64 is a 64-bit variant of ARM for embedded and server systems. The primary sub-architecture referred to as AArch64 (also known as ARMv8-A) is produced by a few manufacturers. AArch64 chips are seen in a variety of SoCs including developer boards, smart phones, tablets, smart TVs, etc. Variants include: ARM Holdings' Cortex-A53, A57, A72, A73 and Qualcomm's Kryo and Falkor.
 * There is no ARM64 Handbook available at this time. Please see.


 * HPPA Handbook
 * Referred to as HPPA, the PA-RISC architecture is an instruction set developed by Hewlett-Packard and was used in their mid- and high-end server series until about 2008 (after which HP started using Intel Itanium). Variants include: HP 9000 and PA-8600.
 * Full sections: Installation – Working – Portage – Networking


 * IA64 Handbook
 * IA64 is a 64-bit architecture designed by Intel and used in their Intel Itanium processor series. This architecture is not compatible with or  (a.k.a. ) and is mostly found in medium and high-end server series. Variants include: Intel Itanium.
 * Full sections: Installation – Working – Portage – Networking


 * MIPS Handbook
 * Developed by MIPS Technologies, the MIPS architecture comprises multiple subfamilies (called revisions) such as MIPS I, MIPS III, MIPS32, MIPS64 and more. MIPS is most common in embedded systems. Variants include: MIPS32 1074K and R16000.
 * Full sections: Installation – Working – Portage – Networking


 * PPC Handbook
 * PPC is a 32-bit architecture used by many Apple, IBM and Motorola processors. They are most commonly found in embedded systems. Variants include: Apple OldWorld, Apple NewWorld, generi Pegasos, Efika, older IBM iSeries and pSeries.
 * Full sections: Installation – Working – Portage – Networking


 * PPC64 Handbook
 * PPC64 is the 64-bit variant of the PPC architecture, popular in both embedded as well as high-end performance servers. Variants include: IBM RS/6000s, IBM pSeries, and IBM iSeries.
 * Full sections: Installation – Working – Portage – Networking


 * SPARC Handbook
 * The SPARC architecture is best known by its most common producers, Sun Microsystems (now Oracle) and Fujitsu. It is used in server systems although a few workstations exist as well. In Gentoo, only SPARC64-compatible CPUs are supported. Variants include: E3000, Blade 1000, and Ultra 2.
 * Full sections: Installation – Working – Portage – Networking


 * X86 Handbook
 * X86 is a 32-bit architecture used by CPUs that are often said to be "Intel compatible". It was until recently the most popular architecture for desktop PCs. Gentoo offers builds for i486 (supports all families) and i686 (supports Pentium and higher or compatible). Variants include: i486, i686, AMD Athlon, Intel Core, and some Intel Atoms.

Can't the Handbook be dynamically generated for each installation choice?
Everything is possible, but we have opted to only do this on a per-architecture level. Other choices, like partitioning, kernel selection, and package installation are easy enough to explain in a single document.

I cannot find stage1 information in the Handbook. Where do I look?
Instructions on using a stage1 or stage2 tarball are now available in the Gentoo FAQ. A stage3 installation is the only supported method of installation.

How do I improve the Handbook?
Suggestions, comments, or ideas on how to make the Handbook better can be reported to the Handbook project via the Discussion page of the respective article. Documentation is made for the community, so community feedback is well appreciated.

Be aware that most decisions made while developing documentation are based on a consensus-model. It is impossible to write or structure documentation in such a way that renders every reader happy.

Those who open discussions with the goal of improving the Handbook must be able to accept a "No" as an answer. Typically "No" is used when we believe the current implementation is beneficial for the majority of readers.

In order to properly track open issues we ask you to add the Talk template to each discussion you open, as seen in the following example:

The  code at the end of the example inserts a dated signature when the page is saved or previewed. This code can either be typed in manually or generated by using the Signature and timestamp button in the edit toolbar. Wiki editors will refer to this as 'signing a discussion.' Please remember to sign each comment made on discussion pages.
