1 Introduction

This document contains the hardware compatibility notes for FreeBSD 5.2.1-RELEASE on the AMD64 hardware platform (also referred to as FreeBSD/amd64 5.2.1-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 AMD64 hardware platform. Versions of the hardware compatibility notes for other architectures will differ in some details.

2 Supported Processors and Motherboards

FreeBSD/amd64 has supported the AMD64 (``Hammer'') architecture since mid-2003. It made its first debut as an experimental release based on FreeBSD 5.1-RELEASE.

As of this writing, this port supports the Athlon64 (``Clawhammer'') and Opteron (``Sledgehammer'') machines. The largest tested memory configuration to date is 8GB. SMP support has been recently completed and is reasonably robust.

In many respects, FreeBSD/amd64 is similar to FreeBSD/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.

FreeBSD/amd64 is a very young platform on FreeBSD. While the core FreeBSD kernel and base system components are generally fairly robust, there are likely to still be rough edges, particularly with third party packages.

3 Supported Devices

$FreeBSD: src/release/doc/en_US.ISO8859-1/hardware/common/dev.sgml,v 1.209 2003/12/07 00:54:22 bmah Exp $

This section describes the devices currently known to be supported by with FreeBSD on the AMD64 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devices are gradually being removed from this document in order to reduce the amount of duplicated (and potentially out-of-date) information contained within.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.
