1 Introduction

This document contains the hardware compatability notes for FreeBSD 4.9-RELEASE on the i386 hardware platform (also referred to as FreeBSD/i386 4.9-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 compatability 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. (While technically supported, the use of the 80386SX is specifically not recommended.) 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 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.

3 Supported Devices

$FreeBSD: src/release/doc/en_US.ISO8859-1/hardware/common/dev.sgml,v 2003/10/01 20:36:57 simon Exp $

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.

WORM/CD-R/CD-RW writing support is provided by cdrecord(1), which is a part of the sysutils/cdrtools port in the Ports Collection.

The following CD-ROM type systems are supported at this time:

  • SCSI interface (also includes ProAudio Spectrum and SoundBlaster SCSI) ( cd(4))

  • Sony proprietary interface (all models) ( scd(4))

The following drivers were supported under the old SCSI subsystem, but are not yet supported under the cam(4) SCSI subsystem:

  • NCR5380/NCR53400 (``ProAudio Spectrum'') SCSI controller

  • UltraStor 14F, 24F and 34F SCSI controllers.

    Note: There is work-in-progress to port the UltraStor driver to the new CAM SCSI framework, but no estimates on when or if it will be completed.
