<hr>

<p>
OpenBSD/amd64 runs on AMD's Athlon-64 family of processors in 64-bit mode.
</p>

<p>
It also runs on the upcoming Intel ia32e processors which contain cloned
support for the AMD64 extensions, but since Intel left out support for
the page table NXE bit (No-EXecute) there is no W^X support on the Intel
cpus.
</p>

<p>
Note that OpenBSD/i386 also runs on these processors, but in 32-bit mode.

<p>
It can be expected to install and run with minimal difficulty on most current
hardware.
<p>

A few problems exist with the bootblocks, kvm libraries, and some floating
point operations.  Obviously this is fairly new, so it will take time to
find other issues and fix them.

<p>
Snapshots are made available from time to time, in
<a href="ftp://ftp.OpenBSD.org/pub/OpenBSD/snapshots/amd64">this location</a>
as well as in a few
<a href="ftp.html">mirrors</a>.
Here are the
<a href="ftp://ftp.OpenBSD.org/pub/OpenBSD/snapshots/amd64/INSTALL.amd64">
OpenBSD/amd64 snapshot installation instructions
</a> as well.
</p>

<p>
There are several installation media provided:
<ul>
  <li><strong>CD boot</strong>
  <p>
  Booting off the CD provides an <i>El Torito</i> 2.88MB floppy image
  that contains almost all OpenBSD drivers.
  This also includes minimal USB support (storage devices and keyboard).<br>
  For the latest list of drivers available on this image, take a look at the
  <a href="http://www.openbsd.org/cgi-bin/cvsweb/src/sys/arch/amd64/conf/RAMDISK_CD?rev=HEAD">RAMDISK_CD</a>
  kernel configuration file.
  </p></li>
  <li><strong>Floppy A</strong> (floppy34.fs)
  <p>
  This 1.44MB floppy image contains the most common drivers.
  It is designed to cover the most typical PC. As a general rule, you will
  find that the missing drivers are ones which need large microcodes to run,
  such as for rare scsi cards, gigabit ethernet cards, or RAID devices.<br>
