OpenBSD/amiga

History and Status:

The Amiga port is basically the same as the NetBSD/amiga port but with some additions. The major changes are:

• 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.

Supported devices include:

• A4000/A1200 IDE controller.
• 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.
• ISA IDE & ATAPI with a supported ISA bridge.
• SCSI host adapters:
  • 33c93 based boards: A2091, A3000 and GVP series II.
  • 53c80 based boards: 12 Gauge, IVS, Emplant and Wordsync/Bytesync.
  • 53c710 based boards: A4091, Magnum, Warp Engine, Zeus and DraCo.
  • FAS216 based boards: FastLane Z3, Blizzard.
• Video controllers:
  • ECS, AGA and A2024 built in on various amigas
  • Retina Z2 and Retina Z3.
  • Picasso II.
  • GVP Spectrum.
  • Piccolo.
  • A2410.
  • Cybervision 64.
  • oMnibus.
  • Domino.
  • Merlin.
• Ethernet controllers:
  • A2065.
  • Hydra.
  • ASDG.
  • A4066.
  • Ariadne.
  • Quicknet.
  • Via a supported ISA bridge:
    • NE[12]000
    • SMC/WD 8003/8013/8216
    • 3COM 3c503.
• Arcnet controllers:
  • A2060.
• Tape drives:
  • Most SCSI tape drives.
• CD-ROM drives:
  • Most SCSI CD-ROM drives.
• Serial ports:
  • Amiga serial port.
  • DraCo serial port.
  • MultiFaceCard II and III.
  • A2232.
  • PC COM ports attached to a supported ISA bridge.
• Parallel ports:
  • Amiga parallel port.
  • PC LPT ports attached to a supported ISA bridge.
• Amiga floppy drives.
• Amiga mouse.

Projects (in no particular order):

• Ramdisk device.
• Make it possible to use the ADOS fs on vnds (virtual block devices)
• Optimize the remapping interrupt system.
• HP-UX emulation.
• NCR SVR3 Unix emulation.
• AMIX emulation.
• Writable ADOSFS.
• Test aic (Adaptec 1522), boca (Boca's multiport serial cards) and perhaps even a Teles S0/16.3 ISDN card.

Snapshots are made available from time to time.
