<hr>

<p>
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, eg R4000 and up.

<h3><font color="#0000e0"><strong>History:</strong></font></h3>

<p>
The OpenBSD/sgi port has its roots in the OpenBSD/arc port created early
in the OpenBSD history. Arc support was rather soon dropped due to lack of
interest and availability of decent hardware. The OpenBSD Mips support have
since then been supported outside the OpenBSD project. As SGI hardware have
become affordable and easy to get by, interest for a SGI port in the tree
have increased. The final piece, a working 64 bit toolchain, is now
available and the 64 bit SGI OpenBSD port is now in the tree.
</p>

<hr>
<a name="status"></a>
<h3><font color="#0000e0"><strong>Current status:</strong></font></h3>

<p>
Currently OpenBSD/sgi runs in 64 bit mode and boot multi-user on supported
systems. Snapshots are made periodically as the port develops and expands.

<h3><font color="#0000e0"><strong>Projects (in no particular order):
</strong></font></h3>

<p>
<ul>
  <li>Support booting and installation from CD-ROM
  <li>Workaround for R10000 CPUs coherency behaviour
  <li>Wscons support for the O2 built in video
  <li>Support the O2 built in audio
  <li>X11 server support
  <li>Larger user VM space. Currently limited to 2GB
  <li>Support more SGI HW like Origin 200, Octance, etc
  <li>Support for multiprocessor systems (<b>not</b> NUMA)
</ul>
</p>

<a name="hardware"></a>
<h3><font color="#0000e0"><strong>Supported hardware:</strong></font></h3>

<p>
<h4>Supported models</h4>

<p>
<ul>
  <li>O2 (aka Moosehead) with R5000, RM5200, RM7000, R10000 and R12000 cpus. Level 2 caches are supported on all CPUs. RM7000 level 3 cache is supported.
<ul>
  <li>Built in Adaptec AIC-7880 SCSI, ahc(4)
  <li>Built in ethernet, mec(4)
  <li>Built in serial ports, com(4)
  <li>64 bit PCI expansion slot
  <li>Intel i8255x-based (except the i82556) PCI ethernet, fxp(4)
</ul>
</ul>

<p>
<h4>Supported peripherals</h4>

<p>
While most models support expansion via PCI many PCI devices may work.
However each device has to be tested before they will be listed here as
supported so if support for a particular device is wanted, suitable hardware
must be made available to a developer who can test and verify functionality.

<strong>Getting and installing OpenBSD/sgi:</strong>
</font></h3>

<p>
OpenBSD/sgi is not yet released in an official release. 
</p>

<p>
Snapshots are made available from time to time, in
<a href="ftp://ftp.OpenBSD.org/pub/OpenBSD/snapshots/sgi">this location</a>
as well as in a few
<a href="ftp.html">mirrors</a>.
Here are the
<a href="ftp://ftp.OpenBSD.org/pub/OpenBSD/snapshots/sgi/INSTALL.sgi">
OpenBSD/sgi snapshot installation instructions
</a> as well.

<p>
Until a bootable CD is avaialble, netbooting is the only available
installation method.
