! 6: <h3><hr>
! 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

! 108:
! 109: <p>
! 110: <h4>OpenBSD/sparc does *not* run on these machines (yet):</h4>

! 114: <li> sun4d: sparc center 1000/2000

! 116: <li> It does not work on most Solbourne machines, which are quite different.
! 117:
! 118: <p>

! 120: A comprehensive list can probably not be written.</h4>
