1.10 miod 23: OpenBSD/aviion is a port of OpenBSD to the Motorola 88100- and
1.1 miod 24: 88110-based AViiON systems manufactured by Data General.

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

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

130: Documentation is available, but there hasn't been any work towards supporting
