The &os; Documentation Project $FreeBSD$ 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 The &os; Documentation Project &tm-attrib.freebsd; &tm-attrib.amd; &tm-attrib.ibm; &tm-attrib.intel; &tm-attrib.sparc; &tm-attrib.sun; &tm-attrib.general; This document contains the hardware compatibility notes for &os; &release.current;. 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. This section provides some architecture-specific information about the specific processors and systems that are supported by each architecture. 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; should support them both. As of this writing, the following processors are supported: &amd.athlon;64 (Clawhammer). &amd.opteron; (Sledgehammer). All multi-core &intel; &xeon; processors except Sossaman have EM64T support. 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; &pentium; D processors &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. &intel; EM64T is an extended version of IA-32 (x86) and different from &intel; IA-64 (Itanium) architecture, which &os;/ia64 supports. Some &intel;'s old documentation refers to &intel; EM64T as 64-bit extension technology or IA-32e. The largest tested memory configuration to date is 32GB. SMP support has been recently completed and is reasonably robust. In many respects, &os;/&arch.amd64; is similar to &os;/&arch.i386;, in terms of drivers supported. There may be some issues with 64-bit cleanliness in some (particularly older) drivers. Generally, drivers that already function correctly on other 64-bit platforms should work. &os;/&arch.amd64; is a very young platform on &os;. While the core &os; kernel and base system components are generally fairly robust, there are likely to still be rough edges, particularly with third party packages. &os;/&arch.i386; runs on a wide variety of IBM PC 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 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 busses 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 HyperThreading (HTT) support on &intel; CPUs that support this feature. A kernel with the options SMP feature enabled will automatically detect the additional logical processors. The default &os; scheduler treats the logical processors the same as additional physical processors; in other words, no attempt is made to optimize scheduling decisions given the shared resources between logical processors within the same CPU. Because this naive scheduling can result in suboptimal performance, under certain circumstances it may be useful to disable the logical processors with the the machdep.hlt_logical_cpus sysctl variable. It is also possible to halt any CPU in the idle loop with the machdep.hlt_cpus sysctl variable. 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; manpage 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. Currently supported processors are the &itanium; and the &itanium; 2. Supported chipsets include: HP zx1 &intel; 460GX &intel; E8870 Both Uniprocessor (UP) and Symmetric Multi-processor (SMP) configurations are supported. Most devices that can be found in or are compatible with &arch.ia64; machines are fully supported. The notable exception is the VGA console. The &os; support for VGA consoles is at this time too much based on PC hardware and not all &arch.ia64; machines have chipsets that provide sufficient PC legacy support. As such &man.syscons.4; can not be enabled and the use of a serial console is required. NEC PC-9801/9821 series with almost all &i386;-compatible processors, including 80486, &pentium;, &pentium; Pro, &pentium; II, and variants. All &i386;-compatible processors by AMD, Cyrix, IBM, and IDT are also supported. NEC FC-9801/9821 series, and NEC SV-98 series (both of them are compatible with PC-9801/9821 series) should be supported. EPSON PC-386/486/586 series, which are compatible with NEC PC-9801 series are supported. High-resolution mode is not supported. NEC PC-98XA/XL/RL/XL^2, and NEC PC-H98 series are supported in normal (PC-9801 compatible) mode only. Although there are some multi-processor systems (such as Rs20/B20), SMP-related features of &os; are not supported yet. PC-9801/9821 standard bus (called C-Bus), PC-9801NOTE expansion bus (110pin), and PCI bus are supported. New Extend Standard Architecture (NESA) bus (used in PC-H98, SV-H98, and FC-H98 series) is not supported. The information for this paragraph has yet to be compiled. This section describes the systems currently known to be supported by &os; on the &ultrasparc; platform. For background information on the various hardware designs see the Sun System Handbook. SMP is supported on all systems with more than 1 processor. In general, &os;/&arch.sparc64; systems must use serial consoles. While it is possible to boot or install a system using the OpenFirmware console, the console device is not usable. If you have a system that is not listed here, it may not have been tested with &os; &release.current;. We encourage you to try it and send a note to the &a.sparc; with your results, including which devices work and which do not. The following systems are fully supported by &os;. &sun.blade; 100 &sun.blade; 150 &sun.enterprise; 220R &sun.enterprise; 250 &sun.enterprise; 420R &sun.enterprise; 450 &sun.fire; V100 &sun.fire; V120 &netra; t1 105 &netra; T1 AC200/DC200 &netra; t 1100 &netra; t 1120 &netra; t 1125 &netra; t 1400/1405 &netra; 120 &netra; X1 &sparcengine; Ultra AXi &sparcengine; Ultra AXmp &sun.ultra; 1 &sun.ultra; 1E &sun.ultra; 2 &sun.ultra; 5 &sun.ultra; 10 &sun.ultra; 30 &sun.ultra; 60 &sun.ultra; 80 The following systems are partially supported by &os;. In particular the onboard SCSI controller in sbus systems is not supported. &sun.enterprise; 3500 &sun.enterprise; 4500 The following systems are not supported by &os;. This may be due to lack of processor support (&ultrasparc; III), due to a quirk in the system design that makes &os; unstable, or due to lack of support for sufficient onboard devices to make &os; generally useful. All systems containing &ultrasparc; III processor(s). This section describes the devices currently known to be supported by &os;. Other configurations may also work, but simply have not been tested yet. Feedback, updates, and corrections to this list are encouraged. Where possible, the drivers applicable to each device or class of devices is listed. If the driver in question has a manual page in the &os; base distribution (most should), it is referenced here. Information on specific models of supported devices, controllers, etc. can be found in the manual pages. The device lists in this document are being generated automatically from &os; manual pages. This means that some devices, which are supported by multiple drivers, may appear multiple times.

WORM devices that support CD-ROM commands are supported for read-only access by the CD-ROM drivers (such as &man.cd.4;). WORM/CD-R/CD-RW writing support is provided by &man.cdrecord.1;, which is a part of the sysutils/cdrtools port in the Ports Collection.
