NetBSD/Sun3
NetBSD 1.1
is the first full release of NetBSD for the Sun3 family of computers.
Features
- Native boot programs for disk, network, and tape
- Automated installation tools (using a "miniroot")
- New SCSI driver supporting DMA, interrupts, and
(optional) disconnect/reselect
- Frame buffer drivers compatible with SunOS and X11R6
- Support for the Virtually Addressed Cache (VAC) on Sun3/2XX models
- SMD disk drivers (need more testing, but reportedly working)
- SunOS 4.1 compatibility (see below)
- Supports most SCSI devices (CD-ROM, etc)
- Diskless boot capability
- Built-in kernel debugger
Machines Supported
NetBSD/Sun3 runs on most sun3 architecture
machines, including:
- Sun3/50, Sun3/60, Sun3/110
- Sun3/75, Sun3/150, Sun3/160
- Sun3/260, Sun3/280
NetBSD/Sun3 does not run on sun3x architecture
machines such as the Sun3/80.
Disk and RAM Requirements
A minimal configuration requires 4M of RAM and about 80MB of disk space.
To install the entire system requires much more disk space (approx.
100MB additional space is necessary for full sources). To run X
or compile the system, more RAM is recommended. Good performance
requires 8MB of RAM, or 16 MB when running the X Window System.
Supported Devices
The following Sun3 devices are currently supported:
- Serial ports: (RS232)
- Video adapters:
- Network interfaces:
- On-board Lance Ethernet (le)
- On-board Intel Ethernet (ie)
- VME Intel Ethernet board (ie)
- SCSI: (Most SCSI disks, tapes, CD-ROMs, etc.)
- On-board Sun3 SCSI interface (si)
- VME Sun3 SCSI board (si)
- SMD Disks: (the big, heavy ones)
- Xylogics 450/451 (xy)
- Xylogics 753/7053 (xd)
- Input devices:
- Miscellaneous:
- Battery-backed real-time clock.
If you have a device that's not listed, it might be compatible with
something else, or we might have simply forgotten it. If all else
fails, maybe you could write a driver!
SunOS 4.1 Compatibility
NetBSD/Sun3 features extensive binary compatibility with
SunOS 4.1.x programs. Static SunOS executables will run without any
extra setup. To run dynamic executables, you'll need to provide the
dynamic libraries that came with your SunOS installation.
SunOS programs that will not work include those that use the
SunOS kvm library, certain (low-level) disk manipulation utilities,
and programs making explicit use of Sun's STREAMS subsystem.
