7: <strong>History and Status:</strong></h3>
8: The original BSD4.4 port was done by Chris Torek as a contract to
9: LBL. The code was released by Chris in mid-93, and Theo de Raadt
10: worked it into shape for the NetBSD tree. Theo and Markus Wild worked
11: on improving Chris' original SunOS compatibility code into a highly
12: complete and reliable emulation. Chuck Cranor ported the sun4c code to
13: the 8KB pagesized Sun4 architecture, and Theo merged this code in a
14: way that would allow the same kernel and programs to run on either
15: sun4c or sun4 machines (unlike Sun's seperate kernel environments).
16: This last change also required a rewrite of the device configuration
17: code. Just after the NetBSD/sparc 1.0 release, Peter Galbavy wrote an
18: ESP scsi device driver as a replacement for Chris' sparc-specific scsi
19: code, this new driver unfortunately had some problems.
20:
21: <p>
22: At this point a conflict emerged between Theo and the other people he
23: started the NetBSD project with, and Theo was forced by the core group
24: to resign from NetBSD. After Theo left NetBSD, a few people in the
25: NetBSD group did some other things for the port: Paul Kranenburg
26: ported a floppy driver and started writing support for the 4/400.
27: Chuck spent many long hours working on the ie, xy, xd device drivers.
28:
29: <p>
30: Theo continued working independently, and made a number of additions:
31: P4 support, flexible boot strategy, a few graphics drivers with help
32: from John Stone, and masses of bug fixes. Many people will be most
33: interested that the ESP scsi driver has been completely replaced by
34: Theo, and that it supports disconnect/reconnect.
35:
36: <p>
37: Work on porting OpenBSD/sparc to the sun4m platform is currently in
38: progress. This work is being done in cooperation between the OpenBSD
39: group and a research group at a US university. This research group
40: wishes to remain anonymous at this time. This work should be
41: available for integration within the next few months.
42:
43: <p>
44: OpenBSD/sparc can be correctly described as NetBSD/sparc + improvements.
45:
46: <p>
47: The people working the most on OpenBSD/sparc currently consists of
48: Chuck Cranor, Theo de Raadt, and David Miller. Of course others are
49: very welcome!

74: <h3><hr>
75: <strong>What hardware is supported?</h3></strong>
76: <h4>OpenBSD/sparc runs on the following classes of machines:</h4>
77: <p>
78: <li> sun4c: the SS1, SS1+, IPC, SLC, SS2, IPX, and ELC
79: <li> sun4: the 4/100, 4/200, and 4/300
80: <li> Typically it works on clones of these machines
81:
82: <p>
83: <h4>Supported devices. This list of basically declares that any `stock' sun4c
84: "sparcstation" machine will probably work; for sun4 machines one must be
85: more careful.</h4>
86: <p>
87: <li> sun4c sbus or on-board cgsix, cgthree, and bwtwo
88: <li> 4/200 on-board bwtwo
89: <li> 4/300 and 4/100 P4 video: bwtwo, cgthree, cgsix. As well, P4 cgeight may work
90: <li> sun4 VME cgtwo, cgthree, cgsix
91: <li> P4 on-board bwtwo, and VME cgtwo card<br>
92: <li> ttya and ttyb serial ports (can be used as console if needed)
93: <li> 4/300 ttyc and ttyc serial ports
94: <li> on-board AMD Lance ethernet
95: <li> sbus AMD Lance ethernet cards
96: <li> on-board Intel 82586 ethernet (ie0 on 4/100 and 4/200)
97: <li> VME Intel 82586 ethernet cards
98: <li> on-board "esp" SCSI controller (sun4c and 4/300)
99: <li> sbus "esp" SCSI controller
100: <li> VME "SUN-3"/"si" SCSI controller (polled mode only, slow)
101: <li> 4/110 "SCSI Weird"/"sw" on-board controller (slow, polled mode)
102: <li> Xylogics 7053 VME/SMD disk controller ("xd")
103: <li> Xylogics 450/451 VME disk controller ("xy")
104: <li> sun4c floppy disk drive
105: <li> sun4c audio
106: <li> sun keyboard and mouse
107: <br>
108:
109: <p>
110: <h4>OpenBSD/sparc does *not* run on these machines (yet):</h4>
111: <p>
112: <li> 4/400 (lacks support for the I/O cache, and has ethernet problems)
113: <li> sun4m: the 4/600, LC, LX, 4, 5, 10, and 20
114: <li> sun4d: sparc center 1000/2000
115: <li> the new Ultra sparc-64 machines...
116: <li> It does not work on most Solbourne machines, which are quite different.
117:
118: <p>
119: <h4>Unsupported Devices. First of all, there are MANY unsupported devices.
120: A comprehensive list can probably not be written.</h4>
121: <p>

123: <li> VME alm2 16-port serial card
124: <li> VME mcp 4-port serial card (or is it 8 port)
125: <li> VME "sc" SCSI controller
126: <li> VME IPI controller
