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

1.12 miod 76: All supported models (or with similar designs) should run multi-user, and
1.13 deraadt 77: are currently limited to serial console.

83: <h4>Supported machines</h4>
84:
85: <ul>
86: <li><strong>100, 200, 300, 400, 3000, 4000 and 4300 series</strong><br>
87: These are the machines initially targetted by this port.
88: Their design is close to the well-known MVME188 design, with different on-board
1.10 miod 89: devices; at the moment, there is no support for the on-board SCSI controller
1.11 deraadt 90: in the boot blocks, although the on-board SCSI controller is supported by the
1.10 miod 91: kernel.<br>
1.6 miod 92: The only models tested so far are models 410 and 4300, but all the models in
1.10 miod 93: this series should work.<br>
94: Multiprocessor systems are not supported.<br>
1.9 miod 95: <li><strong>4600 and 530 series</strong><br>
96: These machines are slightly different from the above series, but not too much,
97: and documentation is available.<br>
98: Both the on-board SCSI controller and the on-board network interface are
1.10 miod 99: supported, and these systems are able to boot from disk.<br>
100: Multiprocessor systems are supported.<br>

1.4 miod 113: <li><strong>5000 and 6000 series</strong><br>
114: These machines may eventually run as well, but lack of on-board device support
1.9 miod 115: might be a showstopper. Some documentation is available, but there hasn't been
1.4 miod 116: any work towards supporting them yet.
117: <li><strong>6280 and 8000-8 series</strong><br>
118: Documentation is available, but there hasn't been any work towards supporting
119: them yet.
120: <li><strong>8500 and 9500 series, and other 88100-based models</strong><br>
121: These systems won't likely be supported unless documentation for them is found.
122: <li><strong>88110-based models (500, 4500, 5500, 8500+ and 9500+ series)</strong><br>
