OpenBSD/aviion
OpenBSD/aviion is an experimental port of OpenBSD to the Motorola 88100- and
88110-based AViiON systems manufactured by Data General.
The current port maintainer is Miod Vallat
(miod@openbsd.org).
Others are definitely welcome to contribute!

History:
In September 2003, Chris Tribo published some excerpts of the technical
documentation for the AViiON series 400. Having a look at it, it was obvious
these systems were built upon a modified MVME188 design, already supported by
OpenBSD/mvme88k, but there was no interest in working
on AViiON support at that time.
Then, late April 2006, enough boredom convinced Miod Vallat to start a port,
even though he did not have access to any AViiON hardware, as a challenge. In two
weeks, thanks to the help of Chris Tribo, a model 410 was running multiuser (but
diskless) - a proof that this effort was worth continuing inside the OpenBSD
tree. And work continues..
Current status:
All supported models (or with similar designs) should run multi-user but
diskless, and currently limited to serial console.
Also, on multiprocessor machines, the system will currently run on one processor
only.
Projects (in no particular order):
- On-board SCSI support on series 400 and compatible models.
- Keyboard and video support.
- Test on as many different models as possible.
- Multiprocessor (SMP) support.
Supported hardware:
Supported machines
- 100, 200, 300, 400, 3000, 4000 and 4300 series
These are the machines initially targetted by this port.
Their design is close to the well-known MVME188 design, with different on-board
devices; at the moment only the on-board serial ports and ethernet are
supported.
The only model tested so far is a model 410, but all the models in this series
should work.
Untested machines
- 500, 5000 and 6000 series
These use a slightly different design and might work, but they are completely
untested.
Unsupported machines
- 88110-based models (550, 4500, 5500, 8500 and 9500 series)
These systems won't likely be supported until the MVME197 works in
mvme88k land. Moreover, these will necessarily use a
different hardware design for which there is no documentation available at the
moment.
