1.10 miod 22: OpenBSD/aviion is a port of OpenBSD to the Motorola 88100- and
1.1 miod 23: 88110-based AViiON systems manufactured by Data General.

48: <p>
49: In September 2003, Chris Tribo published some excerpts of the technical
1.10 miod 50: documentation for the AViiON series 400. From a cursory glance at it, it was
51: obvious these systems were built upon a modified MVME188 design, which was
52: already supported by <a href="mvme88k.html">OpenBSD/mvme88k</a>, but there
53: was no interest in AViiON support at that time.
1.1 miod 54:
55: <p>
56: Then, late April 2006, enough boredom convinced Miod Vallat to start a port,
1.10 miod 57: even though he did not have access to any AViiON hardware, as a challenge.
58: In two weeks, thanks to the help of Chris Tribo, a model 410 was running
59: multiuser (but diskless) - a proof that this effort was worth continuing
60: inside the OpenBSD tree.
61: <p>
62: Work on the port has continued since then, adding support for the 4600/530
63: family, as well as multiprocessor support. The port was left staging until
64: the effort to switch all m88k ports towards the ELF binary file format and
65: shared library paid off, from autumn 2012 to winter 2013.
66: <p>
67: The port eventually became self-hosting on a dual-processor 4600 model in
68: october 2013, with the first working (i.e. recognized by the PROM) boot blocks.
69: <p>
70: And work continues...

1.12 miod 76: All supported models (or with similar designs) should run multi-user, and

97: <li><strong>100, 200, 300, 400, 3000, 4000 and 4300 series</strong><br>
98: These are the machines initially targetted by this port.
99: Their design is close to the well-known MVME188 design, with different on-board
1.10 miod 100: devices; at the moment, there is no support for the on-board SCSI controller
1.11 deraadt 101: in the boot blocks, although the on-board SCSI controller is supported by the
1.10 miod 102: kernel.<br>
1.6 miod 103: The only models tested so far are models 410 and 4300, but all the models in
1.10 miod 104: this series should work.<br>
105: Multiprocessor systems are not supported.<br>
1.9 miod 106: <li><strong>4600 and 530 series</strong><br>
107: These machines are slightly different from the above series, but not too much,
108: and documentation is available.<br>
109: Both the on-board SCSI controller and the on-board network interface are
1.10 miod 110: supported, and these systems are able to boot from disk.<br>
111: Multiprocessor systems are supported.<br>
