<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>
<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 &amp; audio support)
<li>if_ed, although named if_isaed due to name clash
(dp8390 based ethernet cards, like 3c503, NE2000 &amp; 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 partitioning is not found.
<li>Ramdisk device for easy installs
</ul>

<h3><strong>Supported devices include:</strong></h3>
<ul>

<li> A4000/A1200 IDE controller.

<li> ISA bridges:  If you use one of these bridges, and you have
	success with a device not listed below, please inform us.
  <ul>
  <li> The GoldenGate Bus+ (aka GG2).
  <li> The CrossLink.
  </ul>

<li> ISA IDE &amp; 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> 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> Amiga floppy drives.
<li> Amiga mouse.
</ul>


<h3><strong>Projects (in no particular order):</strong></h3>
<ul>

<li>Optimize the remapping interrupt system.
<li>HP-UX emulation.
<li>NCR SVR3 Unix emulation.
<li>AMIX emulation.
<li>Writable ADOSFS.
