In September 2003, Chris Tribo published some excerpts of the technical -documentation for the AViiON series 400.

+Work on the port has continued since then, adding support for the 4600/530 +family, as well as multiprocessor support. The port was left staging until +the effort to switch all m88k ports towards the ELF binary file format and +shared library paid off, from autumn 2012 to winter 2013. +

+The port eventually became self-hosting on a dual-processor 4600 model in +october 2013, with the first working (i.e. recognized by the PROM) boot blocks. +

+And work continues...

Current status:

All supported models (or with similar designs) should run multi-user (some of -them do not support the onboard SCSI controller yet and need to run diskless), -and currently limited to serial console.
