-The Amiga port is basically the same as the NetBSD/amiga port
-but with some additions. The major changes are:
+OpenBSD/amiga runs on the Amiga machines manufactured by Commodore.
+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.
-
-
New interrupt remapping system.
-
Support for using ISA peripherals via a bridgecard.
-
Supports GG2 Bus
-(aka GoldenGate II) and CrossLink bridgecards
-(Neither of these support ISA DMA thus no PC floppy support)
-
Tested ISA devices are
-
-
com (Standard PC serial ports)
-
lpt (Standard PC parallel ports)
-
ast (AST 4-port serial card)
-
wd (IDE harddisk)
-
acd (IDE ATAPI CD, both data & audio support)
-
if_ed, although named if_isaed due to name clash
-(dp8390 based ethernet cards, like 3c503, NE2000 & SMC Ultra).
-
-Others should port easily as long as DMA isn't necessary.
-
SunOS emulation can use shared libraries on the '040
-
Understand BSD disklabels if Amiga RDB partitioning is not found.
-
Ramdisk device for easy installs
-
+
+The OpenBSD/amiga port has been
+discontinued after the 3.2 release.
+
-
Supported devices include:
+
+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.
+If you are interested in reviving the amiga port, make it work and contact
+Niklas Hallqvist.
+
ISA bridges: If you use one of these bridges, and you have
- success with a device not listed below, please inform us.
-
-
The GoldenGate Bus+ (aka GG2).
-
The CrossLink.

+
History:
-
ISA IDE & ATAPI with a supported ISA bridge.
+
+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
+oblivion, although releases were still being made. Eventually, it was decided
+to stop supporting it and remove the code from the tree.
