OpenBSD/sgi currently runs on the 64 bit MIPS-based SGI O2 workstations.
Other 64 bit SGI systems will be supported in the future.
</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

<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. 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, is now available and the 64 bit
SGI OpenBSD port is now available and managed in the OpenBSD source tree.
</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>
In late 2007 the port was expanded with support for the
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=wscons&sektion=4">wscons(4)</a>
framework. This makes it possible to use the glass console.
