1.19 pefo 23: OpenBSD/sgi currently runs on the 64 bit MIPS-based SGI O2 workstations.
24: Other 64 bit SGI systems will be supported in the future.

1.19 pefo 26: <p>
1.20 miod 27: OpenBSD/sgi is a fully featured 64 bit port and will thus only run on systems
28: based on 64 bit processors, i.e. R4000 and up.

1.20 miod 48: The OpenBSD/sgi port has its roots in the <a href="arc.html">OpenBSD/arc</a>
49: port created early in the OpenBSD history. Arc support was rather soon
50: discontinued due to the lack of interest and availability of decent hardware.
51: The OpenBSD Mips support has since then been supported outside the OpenBSD
52: project. As SGI hardware has become affordable and easy to get by, interest
53: for an SGI port in the tree has increased.
54: The final piece, a working 64 bit toolchain, is now available and the 64 bit
55: SGI OpenBSD port is now available and managed in the OpenBSD source tree.

115: must be made available to a developer who can test and verify functionality.
