<p>
OpenBSD/sgi runs on several 64 bit MIPS-based SGI servers and workstations.
</p>
<p>
OpenBSD/sgi is a fully featured 64 bit port and will thus only run on systems
based on 64 bit processors, i.e. R4000 and up.
</p>
<p>
A mailing list dedicated to the OpenBSD/sgi port is available at
<u><font color="#23238e">sgi@openbsd.org</font></u>.
To join the OpenBSD/sgi mailing list, send a message body of <b>"subscribe
sgi"</b> to <a href="mailto:majordomo@openbsd.org">majordomo@openbsd.org</a>.
Please be sure to check our <a href="mail.html">mailing list policy</a> before
subscribing.

The current port maintainers are Miod Vallat
(<a href="mailto:miod@openbsd.org">miod@openbsd.org</a>)
and

<h3><font color="#0000e0"><strong>History</strong></font></h3>
<p>
The OpenBSD/sgi port has its roots in the <a href="arc.html">OpenBSD/arc</a>
port created early in the OpenBSD history. Arc support was rather soon
discontinued due to the lack of interest and availability of decent hardware.
<br>
Eventually SGI hardware became more affordable and obtainable, and interest
for an SGI port in the tree increased.
The final piece, a working 64 bit toolchain, eventually became available and
allowed the 64 bit SGI OpenBSD port to appear in 2004.
<br>
Hardware support was initially limited to the O2 workstations. Efforts
to port to more systems did not really start until 2008, where the first
Octane support parts were introduced. This work was completed in 2009
with support for Origin family systems as well, allowing OpenBSD to be
the first free operating system to run on the Fuel workstations, and even
later, also on Origin 350 servers.
</p>
<a name="status"></a>
<h3><font color="#0000e0"><strong>Current status</strong></font></h3>
<p>
Currently OpenBSD/sgi runs in 64 bit mode and boots multi-user on supported
systems. Snapshots are made periodically as the port develops and expands.
<br>
Not all graphics options are supported on IP27 (Origin) and IP35 (Tezro)
systems yet; in this case the kernel will be limited to serial console
operation only.
<br>
An X server, currently unaccelerated, is also available for IP32 (O2) systems.
</p>
<a name="hardware"></a>
<h3><font color="#0000e0"><strong>Supported hardware</strong></font></h3>
For a complete system component and device driver listing for this architecture, see <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=intro&arch=sgi&sektion=4">intro(4/sgi)</a>.
<p>
The following families are supported:
<ul>
<li>IP27 (Origin) family:
<ul>
<li>Origin 200
</ul>
Origin 2000 and Onyx 2 are not supported yet.
<li>IP30 (Octane a.k.a Speedracer) family:
<ul>
<li>Octane
<li>Octane 2
</ul>
Multiprocessor operation is supported.
<li>IP32 (O2 a.k.a Moosehead) family:
<ul>
<li>O2
<li>O2+
</ul>
R5000, RM5200, RM7000 as well as R10000 and R12000 processors are supported.
RM7000 level 3 cache is supported.
<li>IP35 (Tezro) family:
<ul>
<li>Fuel
<li>Origin 3000 <sup>*</sup>
<li>Origin 350
<li>Tezro <sup>*</sup>
<li>Onyx 4 <sup>*</sup> (currently limited to serial console)
<li>Onyx 350 has not been tested, but ought to work
since it is very similar to Origin 350.
</ul>
Origin 300 and Onyx 300 are not supported yet.
</ul>
<sup>*</sup> support added after the 4.7 release.<br>
Note that <i>Octane 3</i> and <i>Origin 400</i> systems are completely different
architectures based on x86 processors, and as such are not supported
by OpenBSD/sgi.
