| The Amiga port is basically the same as the NetBSD/amiga port |
OpenBSD/amiga runs on the Amiga machines manufactured by Commodore. |
| but with some additions. The major changes are: |
It requires a Motorola 68020 or better processor, with an external Motorola |
| |
68851 PMMU in case of a 68020. |
| |
This leaves out models 500, 600 and 1000 which can not receive accelerator |
| |
boards. |
| </p> |
</p> |
| |
|
| <ul> |
<p> |
| <li>New interrupt remapping system.</li> |
<strong><font color="#e00000">The OpenBSD/amiga port has been |
| <li>Support for using ISA peripherals via a bridgecard.</li> |
discontinued</font></strong> after the 3.2 release. |
| <li>Supports GG2 Bus |
</p> |
| (aka GoldenGate II) and CrossLink bridgecards |
|
| (Neither of these support ISA DMA thus no PC floppy support)</li> |
|
| <li>Tested ISA devices are |
|
| <ul> |
|
| <li>com (Standard PC serial ports)</li> |
|
| <li>lpt (Standard PC parallel ports)</li> |
|
| <li>ast (AST 4-port serial card)</li> |
|
| <li>wd (IDE harddisk)</li> |
|
| <li>acd (IDE ATAPI CD, both data & audio support)</li> |
|
| <li>if_ed, although named if_isaed due to name clash |
|
| (dp8390 based ethernet cards, like 3c503, NE2000 & SMC Ultra).</li> |
|
| </ul> |
|
| Others should port easily as long as DMA isn't necessary.</li> |
|
| <li>SunOS emulation can use shared libraries on the '040</li> |
|
| <li>Understand BSD disklabels if Amiga RDB partitioning is not found.</li> |
|
| <li>Ramdisk device for easy installs</li> |
|
| </ul> |
|
| |
|
| <h3><font color="#0000e0">Supported devices include:</font></h3> |
<p> |
| |
There is currently no one working on bringing this port back to life. |
| |
The source code is still available in the CVS Attic, and code can be found in |
| |
NetBSD as well. |

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. |

After a few years, due to the lack of users, this port was slowly left in |
| <li> 33c93 based boards: A2091, A3000 and GVP series II.</li> |
oblivion, although releases were still being made. Eventually, it was decided |
| <li> 53c80 based boards: 12 Gauge, IVS, Emplant and Wordsync/Bytesync.</li> |
to stop supporting it and remove the code from the tree. |
| <li> 53c710 based boards: A4091, Magnum, Warp Engine, Zeus and DraCo.</li> |
