OpenBSD/amiga used to run on the Amiga machines manufactured by Commodore.
|
|
It used to require a Motorola 68020 or better processor, with an external
|
|
Motorola 68851 PMMU in case of a 68020.
|
|
This left out models 500, 600 and 1000 which cannot receive accelerator
|
|
boards.
|
|
|
|
<p>
|
|
<strong>The OpenBSD/amiga port was discontinued after the 3.2 release.</strong>

<h3 id="history"><strong>History:</strong></h3>
|
|
|
|
<p>
|
|
The OpenBSD/amiga was initially derived from NetBSD/amiga in 1995, and
|
|
used to loosely track the NetBSD changes until 1998. Niklas Hallqvist also
|
|
wrote a new interrupt remapping system, improving average performance,
|
|
revamped the installation media, and ported the ISA bus support to a
|
|
big-endian platform, for GoldenGate II and CrossLink cards.
|
|
|
|
<p>
|
|
After a few years, due to the lack of users, this port was slowly left in
|
|
oblivion, although releases were still being made. Eventually, it was decided
|
|
to stop supporting it and remove the code from the tree.
