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

The current port maintainers are Miod Vallat

<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.
The OpenBSD Mips support has since then been supported outside the OpenBSD
project.
<br>
As SGI hardware has become affordable and easy to come by, interest
for an SGI port in the tree has 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 running on the Fuel workstations.
</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>
On most systems it is currently limited to serial console only.
This is however not the case on O2, on which it is possible to use the glass
console.
</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: <sup>*</sup>
<ul>
<li>Origin 200. Dual-Origin 200 systems using the CRAYlink connection should
work, but currently limited to the first node. <sup>*2</sup>
<li>Origin 2000 and Onyx 2 have not been tested, but should work, currently
limited to the first node. <sup>*2</sup>
</ul>
<li>IP30 (Octane a.k.a Speedracer) family: <sup>*</sup>
<ul>
<li>Octane
<li>Octane 2
</ul>
Octane 3 systems are a completely different architecture based on
x86 processors, and as such are not supported by OpenBSD/sgi.
<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: <sup>*</sup>
<ul>
<li>Fuel
<li>Origin 300, Onyx 300 and Origin 3000 have not been tested, but should
work, currently limited to the first node.
<li>Origin 350 <sup>*3</sup>
<li>Onyx 350, Onyx 4 and Tezro have not been tested, but ought to work
since they are very similar to Origin 350. <sup>*3</sup>
</ul>
</ul>
<sup>*</sup> support for these families has been added after the 4.5 release.
<br>
<sup>*2</sup> support for multiple nodes in <i>M</i> mode
has been added after the 4.6 release.
<br>
<sup>*3</sup> support for these families has been added after the 4.6 release.
