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.
• Ramdisk device for easy installs

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.

• Tape drives:
• Most SCSI tape drives.
• CD-ROM drives:
• Most SCSI CD-ROM drives.
• Serial ports:

Projects (in no particular order):

• Repair the AriadneI ethernet driver.
• Add support for CSMk2/3 scsi controllers.
• Add support for other amiga hardware.
• Fix the cpu detection on the BSD-bootblocks for CS060 owners.
• Write some sort of beginners help for amiga users. (Help wanted)

Snapshots are made available from time to time.
