1 Introduction

This document contains the hardware compatibility notes for FreeBSD 5.2-RELEASE on the i386 hardware platform (also referred to as FreeBSD/i386 5.2-RELEASE). It lists devices known to work on this platform, as well as some notes on boot-time kernel customization that may be useful when attempting to configure support for new devices.

Note: This document includes information specific to the i386 hardware platform. Versions of the hardware compatibility notes for other architectures will differ in some details.

2 Supported Processors and Motherboards

FreeBSD/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 FreeBSD. Nevertheless, some general guidelines are presented here.

Almost all i386-compatible processors are supported. All Intel processors beginning with the 80386 are supported, including the 80386, 80486, Pentium, Pentium Pro, Pentium II, Pentium III, Pentium 4, and variants thereof, such as the Xeon and Celeron processors. (However, FreeBSD 5.2-RELEASE and later no longer support the 80386SX processor.) All i386-compatible AMD processors are also supported, including the Am486, Am5x86, K5, K6 (and variants), Athlon (including Athlon-MP, Athlon-XP, Athlon-4, and Athlon Thunderbird), and 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 FreeBSD, although in some cases, BIOS or motherboard bugs may generate some problems. Perusal of the archives of the FreeBSD symmetric multiprocessing mailing list may yield some clues.

FreeBSD 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 FreeBSD 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 smp(4) manual page has more details.

FreeBSD 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 FreeBSD which may be used; consult the pae(4) manpage for more details.

FreeBSD 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 FreeBSD to work around hardware bugs or other oddities. When in doubt, a search of the archives of the FreeBSD laptop computer mailing list may be useful.

Most modern laptops (as well as many desktops) use the Advanced Configuration and Power Management (ACPI) standard. FreeBSD supports ACPI via the ACPI Component Architecture reference implementation from Intel, as described in the 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:


Users debugging ACPI-related problems may find it useful to disable portions of the ACPI functionality. The 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. FreeBSD can use these DSDTs to override the DSDT provided by the BIOS; see the acpi(4) manual page for more information.

3 Supported Devices

This section describes the devices currently known to be supported by with FreeBSD on the i386 platform. 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 FreeBSD base distribution (most should), it is referenced here. Information on specific models of supported devices, controllers, etc. can be found in the manual pages.

Note: Lists of specific, supported devices are gradually being removed from this document in order to reduce the amount of duplicated (and potentially out-of-date) information contained within. When this process is complete, the manual page for each driver should be consulted for the authoritative list of devices supported that particular driver.
