1.10 ! miod 23: OpenBSD/aviion is a port of OpenBSD to the Motorola 88100- and

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...

76: <p>
1.9 miod 77: All supported models (or with similar designs) should run multi-user (some of
1.10 ! miod 78: them do not support booting from the onboard SCSI controller yet and need to
! 79: boot from a DG/UX setup or run diskless), and currently limited to serial
! 80: console.

102: These are the machines initially targetted by this port.
103: Their design is close to the well-known MVME188 design, with different on-board
1.10 ! miod 104: devices; at the moment, there is no support for the on-board SCSI controller
! 105: in the boot blocks, athough the on-board SCSI controller is supported by the
! 106: kernel.<br>
1.6 miod 107: The only models tested so far are models 410 and 4300, but all the models in
1.10 ! miod 108: this series should work.<br>
! 109: Multiprocessor systems are not supported.<br>
1.9 miod 110: <li><strong>4600 and 530 series</strong><br>
111: These machines are slightly different from the above series, but not too much,
112: and documentation is available.<br>
113: Both the on-board SCSI controller and the on-board network interface are
1.10 ! miod 114: supported, and these systems are able to boot from disk.<br>
