OpenBSD/sgi runs on several 64 bit MIPS-based SGI servers and workstations.
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.
A mailing list dedicated to the OpenBSD/sgi port is available at sgi@openbsd.org. To join the OpenBSD/sgi mailing list, send a message body of "subscribe sgi" to majordomo@openbsd.org. Please be sure to check our mailing list policy before subscribing.
The current port maintainers are Miod Vallat (miod@openbsd.org) and Joel Sing (jsing@openbsd.org).

The OpenBSD/sgi port has its roots in the OpenBSD/arc
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, eventually became available and
allowed the 64 bit SGI OpenBSD port to appear in 2004.
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.
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.
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.
The following families are supported:
The following devices are supported:
The latest supported OpenBSD/sgi release is OpenBSD 4.5. Here are the OpenBSD/sgi 4.5 installation instructions .
Snapshots are made available from time to time, in this location as well as in a few mirrors. Here are the OpenBSD/sgi snapshot installation instructions as well.
