It lists the hardware platforms supported by &os;, as well as the various types of hardware devices (storage controllers, network interfaces, and so on), along with known working instances of these devices. Supported Processors and System Boards This section provides some architecture-specific information about the specific processors and systems that are supported by each architecture. amd64 Since mid-2003 &os;/&arch.amd64; has supported the AMD64 (Hammer) and &intel; EM64T architecture, and is now one of the Tier-1 platforms (fully supported architecture), which are expected to be Production Quality with respects to all aspects of the &os; operating system, including installation and development environments. Note that there are two names for this architecture, AMD64 (AMD) and Intel EM64T (Extended Memory 64-bit Technology). 64-bit mode of the two architectures are almost compatible with each other, and &os;/&arch.amd64; supports them both. As of this writing, the following processors are supported: &amd.athlon;64 (Clawhammer). &amd.opteron; (Sledgehammer). &amd.sempron;. &amd.turion;. &amd.phenom;. All multi-core &intel; &xeon; processors except Sossaman have EM64T support. - The single-core &intel; &xeon; - processors Nocona, Irwindale, + The single-core &intel; &xeon; processors + Nocona, Irwindale, Potomac, and Cranford have EM64T support. All &intel; &core; 2 (not &core; Duo) and later processors All &intel; &core; i range of processors All &intel; &pentium; D processors - All &intel; ¢rino; Duo and ¢rino; Pro platforms + All &intel; ¢rino; Duo and ¢rino; Pro + platforms &intel; &pentium; 4s and &celeron; Ds using the Cedar Mill core have EM64T support. - Some &intel; &pentium; 4s and &celeron; Ds using - the Prescott core have EM64T support. See - the Intel - Processor Spec Finder for the definitive answer about - EM64T support in Intel processors. + Some &intel; &pentium; 4s and &celeron; Ds using the + Prescott core have EM64T support. See the + Intel + Processor Spec Finder for the definitive answer + about EM64T support in Intel processors. &intel; EM64T is an extended version of IA-32 (x86) and different from &intel; IA-64 (Itanium) architecture. Some of &intel;'s old documentation refers to &intel; EM64T as 64-bit extension technology or IA-32e. Both Uniprocessor (UP) and Symmetric Multi-processor (SMP) configurations are supported. In many respects, &os;/&arch.amd64; is similar to &os;/&arch.i386;, in terms of drivers supported. Generally, drivers that already function correctly on other 64-bit platforms should work. - i386 &os;/&arch.i386; runs on a wide variety of IBM PC - compatible machines. Due to the wide range of + compatible machines. Due to the wide range of hardware available for this architecture, it is impossible to exhaustively list all combinations of equipment supported by &os;. Nevertheless, some general guidelines are presented here. Almost all &i386;-compatible processors with a floating - point unit are supported. All &intel; processors beginning + point unit are supported. All &intel; processors beginning with the 80486 are supported, including the 80486, &pentium;, &pentium; Pro, &pentium; II, &pentium; III, &pentium; 4, and variants thereof, such as the &xeon; and &celeron; processors. All &i386;-compatible AMD processors are also supported, including the &am486;, &am5x86;, K5, &amd.k6; (and variants), &amd.athlon; (including Athlon-MP, Athlon-XP, Athlon-4, and Athlon Thunderbird), and &amd.duron; processors. The AMD Élan SC520 embedded processor is supported. The Transmeta Crusoe is recognized and supported, as are &i386;-compatible processors from Cyrix and NexGen. There is a wide variety of motherboards available for this architecture. Motherboards using the ISA, VLB, EISA, AGP, and PCI expansion buses are well-supported. There is some limited support for the MCA (MicroChannel) expansion bus used in the IBM PS/2 line of PCs. Symmetric multi-processor (SMP) systems are generally supported by &os;, although in some cases, BIOS or motherboard bugs may generate some problems. Perusal of the archives of the &a.smp; may yield some clues. &os; will take advantage of SMT (Symmetric MultiThreading, also known as HyperThreading on &intel; CPUs) on the supported CPUs. The GENERIC kernel which is installed by default will automatically detect the additional logical processors. The default &os; scheduler recognizes processor topology on the system and selects logical and physical processors to obtain optimal performance. The &man.smp.4; manual page has more details. &os; will take advantage of Physical Address Extensions (PAE) support on CPUs that support this feature. A kernel with the PAE feature enabled will detect memory above 4 gigabytes and allow it to be used by the system. This feature places constraints on the device drivers and other features of &os; which may be used; consult the &man.pae.4; manual page for more details. &os; will generally run on i386-based laptops, albeit with varying levels of support for certain hardware features such as sound, graphics, power management, and PCCARD expansion slots. These features tend to vary in idiosyncratic ways between machines, and frequently require special-case support in &os; to work around hardware bugs or other oddities. When in doubt, a search of the archives of the &a.mobile; may be useful. Most modern laptops (as well as many desktops) use the Advanced Configuration and Power Management (ACPI) standard. &os; supports ACPI via the ACPI Component Architecture reference implementation from &intel;, as described in the &man.acpi.4; manual page. The use of ACPI causes instabilities on some machines and it may be necessary to disable the ACPI driver, which is normally loaded via a kernel module. This may be accomplished by adding the following line to /boot/device.hints: hint.acpi.0.disabled="1" Users debugging ACPI-related problems may find it useful to disable portions of the ACPI functionality. The &man.acpi.4; manual page has more information on how to do this via loader tunables. ACPI depends on a Differentiated System Descriptor Table (DSDT) provided by each machine's BIOS. Some machines have bad or incomplete DSDTs, which prevents ACPI from functioning correctly. Replacement DSDTs for some machines can be found - at the DSDT - section of the ACPI4Linux project - Web site. &os; can use these DSDTs to override the DSDT - provided by the BIOS; see the &man.acpi.4; manual page for - more information. + at the DSDT + section of the ACPI4Linux + project Web site. &os; can use these DSDTs to override the + DSDT provided by the BIOS; see the &man.acpi.4; manual page + for more information. powerpc - All Apple PowerPC machines with built-in USB are supported, - as well a limited selection of non-Apple machines, + All Apple PowerPC machines with built-in USB are + supported, as well a limited selection of non-Apple machines, including KVM on POWER7 SMP is supported on all systems with more than 1 processor. sparc64 This section describes the systems currently known to be - supported by &os; on the Fujitsu &sparc64; and Sun &ultrasparc; - platforms. + supported by &os; on the Fujitsu &sparc64; and Sun + &ultrasparc; platforms.

This release of &os; contains everything you need to run such a system, including full source code for the kernel and all utilities in the base distribution. With the source distribution installed, you can literally recompile the entire system from scratch with one command, making it ideal for students, researchers, or users who simply want to see how it all works. A large collection of third-party ported software (the Ports Collection) is also provided to make it - easy to obtain and install all your favorite traditional &unix; - utilities for &os;.

This section focuses on those ways that are primarily useful for obtaining a complete &os; distribution, rather than updating an existing installation. CDROM and DVD &os; -RELEASE distributions may be ordered on CDROM or DVD from several publishers. This is frequently the most convenient way to obtain &os; for new installations, as it provides a convenient way to quickly reinstall the system if necessary. Some distributions include some of the optional, precompiled packages from the &os; Ports Collection, or other extra material.

Lists of locations that mirror &os; can be found in the FTP Sites section of the Handbook. Finding a close (in networking terms) mirror from which to download the distribution is highly recommended. Additional mirror sites are always welcome. Contact freebsd-admin@FreeBSD.org for more details on becoming an official mirror site.

Mirrors generally contain the ISO images generally used to create a CDROM of a &os; release. They usually also contain floppy disk images (for applicable platforms), as well as the files necessary to do an installation over the network. Finally mirrors sites usually contain a set of packages for the most current release.

Do not send email to the lists asking to be subscribed. Use the Mailman interface instead. Submitting Problem Reports Suggestions, bug reports and contributions of code are always valued—please do not hesitate to report any problems you may find. Bug reports with attached fixes are of course even more welcome. The preferred method to submit bug reports from a machine with Internet connectivity is to use the Bugzilla bug tracker. Problem Reports (PRs) submitted in this way will be filed and their progress tracked; the &os; developers will do their best to respond to all reported bugs as soon as possible. A list of all active PRs is available on the &os; Web site; this list is useful to see what potential problems other users have encountered. Note that &man.send-pr.1; is deprecated. For more information, Writing &os; Problem Reports, available on the &os; Web site, has a number of helpful hints on writing and submitting effective problem reports.

All users are encouraged to consult the release errata before installing &os;. The errata document is updated with late-breaking information discovered late in the release cycle or after the release. Typically, it contains information on known bugs, security advisories, and corrections to documentation. An up-to-date copy of the errata for &os; &release.current; can be found on the &os; Web site. This document describes the most user-visible new or changed features in &os; since &release.prev;. In general, changes described here are unique to the &release.branch; branch unless specifically marked as &merged; features. Typical release note items document recent security advisories issued after &release.prev;, new drivers or hardware support, new commands or options, major bug fixes, or contributed software upgrades. They may also list changes to major ports/packages or release engineering practices. Clearly the release notes cannot list every single change made to &os; between releases; this document focuses primarily on security advisories, user-visible changes, and major architectural improvements. Upgrading from Previous Releases of &os; Binary upgrades between RELEASE versions (and snapshots of the various security branches) are supported using the &man.freebsd-update.8; utility. The binary upgrade procedure will update unmodified userland utilities, as well as unmodified GENERIC kernels distributed as a part of an official &os; release. The &man.freebsd-update.8; utility requires that the host being upgraded have Internet connectivity. Source-based upgrades (those based on recompiling the &os; base system from source code) from previous versions are supported, according to the instructions in /usr/src/UPDATING. Upgrading &os; should only be attempted after backing up all data and configuration files.
