<h2>OpenBSD/amiga</h2>
<hr>
<h3><strong>History and Status:</strong></h3>
<p>
The Amiga port is basically the same as the NetBSD/amiga port
but with some additions. The major changes are:
</p>
<ul>
<li>New interrupt remapping system.
<li>Support for using ISA peripherals via a bridgecard.
<li>Supports <a href=http://www.infinet.com/~erd/GG2/>GG2 Bus+</a>
(aka GoldenGate II) and CrossLink bridgecards
(Neither of these support ISA DMA thus no PC floppy support)
<li>Tested ISA devices are
<ul>
<li>com (Standard PC serial ports)
<li>lpt (Standard PC parallel ports)
<li>ast (AST 4-port serial card)
<li>wd (IDE harddisk)
<li>acd (IDE ATAPI CD, both data & audio support)
<li>if_ed, although named if_isaed due to name clash
(dp8390 based ethernet cards, like 3c503, NE2000 & SMC Ultra).
</ul>
Others should port easily as long as DMA isn't necessary.
<li>SunOS emulation can use shared libraries on the '040
<li>Understand BSD disklabels if Amiga RDB partitining is not found.
</ul>
</p>
<h3><strong>Supported devices include:</strong></h3>
<ul>
<li> A4000/A1200 IDE controller.
<li> ISA IDE & ATAPI with a supported ISA bridge.
<li> SCSI host adapters:
<ul>
<li> 33c93 based boards: A2091, A3000 and GVP series II.
<li> 53c80 based boards: 12 Gauge, IVS, Emplant and Wordsync/Bytesync.
<li> 53c710 based boards: A4091, Magnum, Warp Engine, Zeus and DraCo.
<li> FAS216 based boards: FastLane Z3, Blizzard.
</ul>
<li> Video controllers:
<ul>
<li> ECS, AGA and A2024 built in on various amigas
<li> Retina Z2 and Retina Z3.
<li> Picasso II.
<li> GVP Spectrum.
<li> Piccolo.
<li> A2410.
<li> Cybervision 64.
<li> oMnibus.
<li> Domino.

</ul>
<li> Ethernet controllers:
<ul>
<li> A2065.
<li> Hydra.
<li> ASDG.
<li> A4066.
<li> Ariadne.

<li> Via a supported ISA bridge:
<ul>
<li> NE[12]000
<li> SMC/WD 8003/8013/8216
<li> 3COM 3c503.
</ul>
</ul>
<li> Arcnet controllers:
<ul>
<li> A2060.
</ul>
<li> Tape drives:
<ul>
<li> Most SCSI tape drives.
</ul>
<li> CD-ROM drives:
<ul>
<li> Most SCSI CD-ROM drives.
</ul>
<li> Serial ports:
<ul>
<li> Amiga serial port.
<li> DraCo serial port.
<li> MultiFaceCard II and III.
<li> A2232.
<li> PC COM ports attached to a supported ISA bridge.
</ul>
<li> Parallel ports:
<ul>
<li> Amiga parallel port.
<li> PC LPT ports attached to a supported ISA bridge.
</ul>
<li> ISA bridges:
<ul>
<li> The GoldenGate Bus+ (aka GG2).
<li> The CrossLink.
</ul>
<li> Amiga floppy drives.
<li> Amiga mouse.
</ul>
<h3><strong>Projects (in no particular order):</strong></h3>
<ul>
<li>Ramdisk device.
<li>Make it possible to use the ADOS fs on vnds (virtual block devices)
<li>Optimize the remapping interrupt system.
<li>HP-UX emulation.
<li>NCR SVR3 Unix emulation.
<li>AMIX emulation.
<li>Writable ADOSFS.
<li>Test aic (Adaptec 1522), boca (Boca's multiport serial cards) and
perhaps even a Teles S0/16.3 ISDN card.
</ul>
