1.95 miod 36:
37: <p>
38: The OpenBSD/alpha port was started in the summer of 1996 by using code
39: from the NetBSD/alpha port which was started by
40: <a href="mailto:cgd@netbsd.org">Chris Demetriou</a> in 1994.
41: After the original OpenBSD port, some
1.45 niklas 42: copyright issues prevented OpenBSD from tracking the NetBSD code.
43: Regardless, work on the alpha port continued and many fixes were made.
1.95 miod 44: Meanwhile, NetBSD continued to make improvements to the
1.83 horacio 45: alpha port which we were unfortunately unable to use. Over time,
1.45 niklas 46: because of a lack of programmer resources and the inability to use
47: NetBSD code, hardware and software support became very outdated. This
48: caused the 2.5 and 2.6 releases of alpha to have few kernel
1.95 miod 49: enhancements. As a result of its becoming so stale, there was no
50: OpenBSD/alpha port included in the 2.7 and 2.8 releases.
1.45 niklas 51:
1.95 miod 52: <p>
1.264 tedu 53: Shortly after OpenBSD 2.8 was released, there was a great deal of
1.95 miod 54: interest in bringing the port up to date. This, coupled with the fact
55: that NetBSD changed the license on its alpha code so that there were no
1.264 tedu 56: longer copyright issues led to an effort to bring the alpha port
1.50 nate 57: back up. (For details on why we were not able to keep tracking the
1.95 miod 58: NetBSD code, check our <a href="policy.html">policy</a> page.)
1.50 nate 59:
1.95 miod 60: <p>
61: Nathan Binkert, Art Grabowski, Niklas Hallqvist and Eric Jackson, with
1.234 sthen 62: the help of a few others, eventually brought the port into good shape
1.95 miod 63: again, and starting with the 2.9 release OpenBSD/alpha is a supported
64: OpenBSD port again.

71: Currently, all the hardware listed in the
1.120 nick 72: <a href="#hardware">supported hardware</a> section below boots
1.95 miod 73: multi-user, and supports enough of the on-board devices to be generally
1.119 pedro 74: usable, unless specified otherwise.
1.95 miod 75: A large set of PCI cards also work reliably, while ISA devices support has
76: limitations.

86: To the best of our knowledge, the following hardware is supported, but there
87: might be occasional breakage on some models.
88: Since there are many models and combinations that have not been tested,
89: we would appreciate very much if you told us about things that work and
90: do not work.
91: To help us keep track of what hardware people use, please mail your dmesg to
