! 20:
! 21: <p>
1.1 deraadt 22: The original BSD4.4 port was done by Chris Torek as a contract to
23: LBL. The code was released by Chris in mid-93, and Theo de Raadt
24: worked it into shape for the NetBSD tree. Theo and Markus Wild worked
25: on improving Chris' original SunOS compatibility code into a highly
26: complete and reliable emulation. Chuck Cranor ported the sun4c code to
27: the 8KB pagesized Sun4 architecture, and Theo merged this code in a
28: way that would allow the same kernel and programs to run on either
29: sun4c or sun4 machines (unlike Sun's seperate kernel environments).
30: This last change also required a rewrite of the device configuration
31: code. Just after the NetBSD/sparc 1.0 release, Peter Galbavy wrote an
32: ESP scsi device driver as a replacement for Chris' sparc-specific scsi
33: code, this new driver unfortunately had some problems.

1.1 deraadt 35:
36: <p>
37: At this point a conflict emerged between Theo and the other people he
38: started the NetBSD project with, and Theo was forced by the core group
39: to resign from NetBSD. After Theo left NetBSD, a few people in the
40: NetBSD group did some other things for the port: Paul Kranenburg
41: ported a floppy driver and started writing support for the 4/400.
42: Chuck spent many long hours working on the ie, xy, xd device drivers.
1.3 ! fn 43: </p>
1.1 deraadt 44:
45: <p>
46: Theo continued working independently, and made a number of additions:
47: P4 support, flexible boot strategy, a few graphics drivers with help
48: from John Stone, and masses of bug fixes. Many people will be most
49: interested that the ESP scsi driver has been completely replaced by
50: Theo, and that it supports disconnect/reconnect.

1.1 deraadt 52:
53: <p>
54: Work on porting OpenBSD/sparc to the sun4m platform is currently in
55: progress. This work is being done in cooperation between the OpenBSD
56: group and a research group at a US university. This research group
57: wishes to remain anonymous at this time. This work should be
58: available for integration within the next few months.

61: <p>
62: OpenBSD/sparc can be correctly described as NetBSD/sparc + improvements.

66: The people working the most on OpenBSD/sparc currently consists of
1.3 ! fn 67: Chuck Cranor, Theo de Raadt, and David Miller. Of course, others are
1.1 deraadt 68: very welcome!
