<p>
Quick installer information for people familiar with OpenBSD, and the use of
the "<a href="https://man.openbsd.org/disklabel.8">disklabel</a> -E" command.
If you are at all confused when installing OpenBSD, read the relevant
INSTALL.* file as listed above!
<h3>OpenBSD/alpha:</h3>
<p>
If your machine can boot from CD, you can write <i>install68.iso</i> or
<i>cd68.iso</i> to a CD and boot from it.
Refer to INSTALL.alpha for more details.
<h3>OpenBSD/amd64:</h3>
<p>
If your machine can boot from CD, you can write <i>install68.iso</i> or
<i>cd68.iso</i> to a CD and boot from it.
You may need to adjust your BIOS options first.
<p>
If your machine can boot from USB, you can write <i>install68.fs</i> or
<i>miniroot68.fs</i> to a USB stick and boot from it.
<p>
If you can't boot from a CD, floppy disk, or USB,
you can install across the network using PXE as described in the included
INSTALL.amd64 document.
<p>
If you are planning to dual boot OpenBSD with another OS, you will need to
read INSTALL.amd64.
<h3>OpenBSD/arm64:</h3>
<p>
Write <i>miniroot68.fs</i> to a disk and boot from it after connecting
to the serial console. Refer to INSTALL.arm64 for more details.
<h3>OpenBSD/armv7:</h3>
<p>
Write a system specific miniroot to an SD card and boot from it after connecting
to the serial console. Refer to INSTALL.armv7 for more details.
<h3>OpenBSD/hppa:</h3>
<p>
Boot over the network by following the instructions in INSTALL.hppa or the
<a href="hppa.html#install">hppa platform page</a>.
<h3>OpenBSD/i386:</h3>
<p>
If your machine can boot from CD, you can write <i>install68.iso</i> or
<i>cd68.iso</i> to a CD and boot from it.
You may need to adjust your BIOS options first.
<p>
If your machine can boot from USB, you can write <i>install68.fs</i> or
<i>miniroot68.fs</i> to a USB stick and boot from it.
<p>
If you can't boot from a CD, floppy disk, or USB,
you can install across the network using PXE as described in
the included INSTALL.i386 document.
<p>
If you are planning on dual booting OpenBSD with another OS, you will need to
read INSTALL.i386.
<h3>OpenBSD/landisk:</h3>
<p>
Write <i>miniroot68.fs</i> to the start of the CF
or disk, and boot normally.
<h3>OpenBSD/loongson:</h3>
<p>
Write <i>miniroot68.fs</i> to a USB stick and boot bsd.rd from it
or boot bsd.rd via tftp.
Refer to the instructions in INSTALL.loongson for more details.
<h3>OpenBSD/luna88k:</h3>
<p>
Copy 'boot' and 'bsd.rd' to a Mach or UniOS partition, and boot the bootloader
from the PROM, and then bsd.rd from the bootloader.
Refer to the instructions in INSTALL.luna88k for more details.
<h3>OpenBSD/macppc:</h3>
<p>
Burn the image from a mirror site to a CDROM, and power on your machine
while holding down the <i>C</i> key until the display turns on and
shows <i>OpenBSD/macppc boot</i>.
<p>
Alternatively, at the Open Firmware prompt, enter <i>boot cd:,ofwboot
/6.8/macppc/bsd.rd</i>
<h3>OpenBSD/octeon:</h3>
<p>
After connecting a serial port, boot bsd.rd over the network via DHCP/tftp.
Refer to the instructions in INSTALL.octeon for more details.
<h3>OpenBSD/powerpc64:</h3>
<p>
After XXX
Refer to the instructions in INSTALL.powerpc64 for more details.
<h3>OpenBSD/sgi:</h3>
<p>
To install, burn cd68.iso on a CD-R, put it in the CD drive of your
machine and select <i>Install System Software</i> from the System Maintenance
menu. Indigo/Indy/Indigo2 (R4000) systems will not boot automatically from
CD-ROM, and need a proper invocation from the PROM prompt.
Refer to the instructions in INSTALL.sgi for more details.
<p>
If your machine doesn't have a CD drive, you can setup a DHCP/tftp network
server, and boot using "bootp()/bsd.rd.IP##" using the kernel matching your
system type. Refer to the instructions in INSTALL.sgi for more details.
<h3>OpenBSD/sparc64:</h3>
<p>
Burn the image from a mirror site to a CDROM, boot from it, and type
<i>boot cdrom</i>.
<p>
If this doesn't work, or if you don't have a CDROM drive, you can write
<i>floppy68.fs</i> or <i>floppyB68.fs</i>
(depending on your machine) to a floppy and boot it with <i>boot
floppy</i>. Refer to INSTALL.sparc64 for details.
<p>
Make sure you use a properly formatted floppy with NO BAD BLOCKS or your install
will most likely fail.
<p>
You can also write <i>miniroot68.fs</i> to the swap partition on
the disk and boot with <i>boot disk:b</i>.
<p>
If nothing works, you can boot over the network as described in INSTALL.sparc64.

<h3>How to upgrade</h3>
<p>
If you already have an OpenBSD 6.7 system, and do not want to reinstall,
upgrade instructions and advice can be found in the
<a href="faq/upgrade68.html">Upgrade Guide</a>.
</section>
<hr>
<section id=sourcecode>
<h3>Notes about the source code</h3>
<p>
<code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
This file contains everything you need except for the kernel sources,
which are in a separate archive.
To extract:
<blockquote><pre>
# <kbd>mkdir -p /usr/src</kbd>
# <kbd>cd /usr/src</kbd>
# <kbd>tar xvfz /tmp/src.tar.gz</kbd>
</pre></blockquote>
<p>
<code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
This file contains all the kernel sources you need to rebuild kernels.
To extract:
<blockquote><pre>
# <kbd>mkdir -p /usr/src/sys</kbd>
# <kbd>cd /usr/src</kbd>
# <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
</pre></blockquote>
<p>
Both of these trees are a regular CVS checkout. Using these trees it
is possible to get a head-start on using the anoncvs servers as
described <a href="anoncvs.html">here</a>.
Using these files
results in a much faster initial CVS update than you could expect from
a fresh checkout of the full OpenBSD source tree.
</section>
<hr>
<section id=ports>
<h3>Ports Tree</h3>
<p>
A ports tree archive is also provided. To extract:
<blockquote><pre>
# <kbd>cd /usr</kbd>
# <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
</pre></blockquote>
<p>
Go read the <a href="faq/ports/index.html">ports</a> page
if you know nothing about ports
at this point. This text is not a manual of how to use ports.
Rather, it is a set of notes meant to kickstart the user on the
OpenBSD ports system.
<p>
The <i>ports/</i> directory represents a CVS checkout of our ports.
As with our complete source tree, our ports tree is available via
<a href="anoncvs.html">AnonCVS</a>.
So, in order to keep up to date with the -stable branch, you must make
the <i>ports/</i> tree available on a read-write medium and update the tree
with a command like:
<blockquote><pre>
# <kbd>cd /usr/ports</kbd>
# <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_6_8</kbd>
</pre></blockquote>
<p>
[Of course, you must replace the server name here with a nearby anoncvs
server.]
<p>
Note that most ports are available as packages on our mirrors. Updated
ports for the 6.8 release will be made available if problems arise.
<p>
If you're interested in seeing a port added, would like to help out, or just
would like to know more, the mailing list
<a href="mail.html">ports@openbsd.org</a> is a good place to know.
