The tiny bits of OpenBSD that are completely specific to the Sun3
-port are basically the same as their NetBSD counterparts but with some
-additions. The major changes are:
+
+The OpenBSD/sun3 port currently runs on all the 68020-based Sun3 computers, except the 3/E
+flavour.
+
History and Status:
+
+The Sun3 port of OpenBSD was derived from the NetBSD/sun3 port, when the sun3 and sun3x
+ports were still different entities. The tiny bits of OpenBSD that are
+completely specific to the Sun3 port are basically the same as their NetBSD
+counterparts.
+
+
+
+
Supported Hardware:
+OpenBSD/sun3 runs on the following Sun-3 models:
-
default data resource limit raised to 16384 Kbytes so that "make build"
- does not crash in libc.
-
+Other Sun-3 models are NOT supported, especially 68030-based ones (sun3x).
+
-
+
Supported devices:
+
+
On-board serial ports
+
Sun type 3 keyboard and mouse
+
On-board or VME video (bwtwo, cgtwo, cgfour)
+
On-board or VME ethernet (intel, lance)
+
On-board or VME sun-3 scsi controller, currently with some limitations
+
VME xylogics cards are recognized but currently not working
+
+The sun-2 scsi controller is not supported yet.
-Snapshots of the kernel and diskless bootstrap loader are available.
-If you want to use OpenBSD/sun3 get an Amiga (or
-any other m68k OpenBSD) snapshot and the Sun3 GENERIC kernel
-and diskless bootstrap loader then if you don't know how to set up
-a diskless box read the diskless(8)
-manpage. Use the MAKEDEV from src/etc.sun3.
-Once you have booted the Sun3 diskless you should be able to "cd
-/usr/src; make obj; make build" to get a native OpenBSD/Sun3.
-Before doing this kernel instrumentation ("ps", "netstat", etc.)

+There is no formal OpenBSD/sun3 release yet.
+Full snapshots, including userland, kernel, diskless and ufs bootstrap loaders
