OpenBSD/i386 runs on the standard PCs and clones, with a wide variety
|
|
of processors, I/O bus architectures and peripherals supported.

<h3 id="history"><strong>History:</strong></h3>
|
|
|
|
<p>
|
|
The OpenBSD/i386 port has been present since the inception of the project.
|
|
Over the years, more and more hardware support has been written
|
|
specifically for OpenBSD (such as the cryptographic accelerator drivers),
|
|
or adapted from FreeBSD and NetBSD.
|
|
|
|
<hr>
|
|
|
|
<h3 id="status"><strong>Current status:</strong></h3>
|
|
|
|
<p>
|
|
It can be expected to install and run with minimal difficulty on most current
|
|
hardware.
|
|
Machines using custom BIOS (such as older proprietary PCs, laptops, and some
|
|
specialized server machines) may cause problems.
|
|
|
|
<p>
|
|
X Window System support is available for most graphics cards, using
|
|
the X.Org server. As with other free operating systems, it is highly recommended
|
|
that Nvidia cards are avoided since this vendor continues to show tremendous
|
|
resistance towards releasing information that would allow X.Org to support their
|
|
hardware properly.
|
|
|
|
<p>
|
|
Due to the increased usage of <a href="amd64.html">OpenBSD/amd64</a>, as well
|
|
as the age and practicality of most i386 hardware, only easy and critical
|
|
security fixes are backported to i386. The project has more important things
|
|
to focus on.

<h3 id="hardware"><strong>Supported hardware:</strong></h3>
|
|
|
|
<h4>Processors</h4>
|
|
|
|
<p>
|
|
All CPUs compatible with the Intel Pentium or later, with Intel-compatible
|
|
hardware floating point support should work.
|
|
|
|
<h4>SMP support</h4>
|
|
|
|
<p>
|
|
OpenBSD/i386 supports most SMP (Symmetrical MultiProcessor) systems,
|
|
including multi-chip, multi-core and/or hyperthreading designs.
|
|
To support SMP operation, a separate SMP kernel (<code>bsd.mp</code>) is
|
|
included with the installation file sets.
|
|
|
|
<h3>Unsupported Hardware:</h3>
|
|
|
|
<p>
|
|
New hardware is constantly being released, some of which may lack support.
|
|
Your <a href="donations.html">donation of time, hardware, or documentation</a>
|
|
can accelerate this support!

|
<h3 id="multiboot"><strong>Installation with other operating systems:
|
|
</strong></h3>
|
|
|
|
<p>
|
|
OpenBSD/i386 can be installed to share the system disks with other operating
|
|
systems, such as MS-DOS, Windows or Linux, using the MBR/partition table
|
|
scheme, and an optional boot selector program.
|
|
Everyday operation is trouble free, but setup requires care, and several
|
|
operating systems, such as Windows 95, are known to be careless about
|
|
pre-existing MBR information.
|
|
|
|
<p>
|
|
Also, some laptop computers use a specific partition as suspend-to-disk
|
|
storage, which should not be clobbered.
|
|
|
|
<p>
|
|
More details on this process can be found in the
|
|
<a href="faq/faq4.html">Installation Guide</a> and

<strong>Getting and installing OpenBSD/i386:</strong>
|
|
</h3>
|
|
|
|
<p>
|
|
The latest supported OpenBSD/i386 release is
|
|
<a href="73.html">OpenBSD 7.3</a>.
|
|
Here are the
|
|
<a href="https://ftp.openbsd.org/pub/OpenBSD/7.3/i386/INSTALL.i386">
|
|
OpenBSD/i386 installation instructions</a>.
|
|
|
|
<p>
|
|
Snapshots are made available from time to time, in
|
|
<a href="https://cdn.openbsd.org/pub/OpenBSD/snapshots/i386">this location</a>
|
|
as well as on a few
|
|
<a href="ftp.html">mirrors</a>.
|
|
Here are the
|
|
<a href="https://ftp.openbsd.org/pub/OpenBSD/snapshots/i386/INSTALL.i386">
|
|
OpenBSD/i386 snapshot installation instructions</a> as well.
|
|
|
|
<p>
|
|
There are several installation media provided:
|
|
|
|
<ul>
|
|
<li><strong>CD image</strong> (install73.iso)
|
|
<br>
|
|
The CD ISO provides an <i>El Torito</i> no-emulation boot image
|
|
that includes 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="https://cvsweb.openbsd.org/src/sys/arch/i386/conf/RAMDISK_CD?rev=HEAD">RAMDISK_CD</a>
|
|
kernel configuration file.
|
|
<li><strong>Disk image</strong> (miniroot73.img)
|
|
<br>
|
|
The same installer as the CD ISO, but in a form suitable for creating bootable
|
|
hard drives or USB flash drives.
|
|
<li><strong>Floppy</strong> (floppy73.img)
|
|
<br>
|
|
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>
|
|

|
|
kernel configuration file.
