History and Status:
The OpenBSD/alpha port was begun in the summer of 1996 by using
***************
*** 28,44 ****
NetBSD code, hardware and software support became very outdated. This
caused the 2.5 and 2.6 releases of alpha to have few kernel
enhancements. As a result of its becoming so stale, alpha was not
! included in the 2.7 release.
!
Recently, there has been a great deal of interest in bringing the
! port up to date. This coupled with the fact that NetBSD changed the
! license on its alpha code so that there are no longer copyright issues
! has lead to an effort to bring the alpha port back up. (For details on
! why we were not able to keep tracking the NetBSD code, check our policy page.)
!
There is currently no maintainer for the alpha port. Technical
! discussion about the alpha port should be directed to <alpha@openbsd.org>. If you
are at all interested in development of the alpha port, please send
inquiries to this address. If you are interested in the job of alpha

Nate Binkert, Art Grabowski, Niklas Hallqvist and Eric Jackson,

Snapshots:
!
While we are bringing the alpha port back to life snapshots will be
! unpredictable an sporadic at best. If you are interested in helping
! out, we encourage you to grab a snapshot, sync with -current and dig
! in!
Testing more platforms and peripherals, to find what issues are remaining
!
Better documentation
!
compat_osf1 shared libs
!
bus_dma on more core chipsets
!
isa_dma
!
Floppy support (needs isa_dma first)
!
Fix 64-bit issues in the non-working PCI drivers
!
Improve TGA support to include virtual consoles
!
Improve X11 support
Supported Hardware:
Because of the changes that are currently being made to alpha, the
currently supported hardware is in flux. To the best of our
! knowledge, the following hardware is supported, but there might be
! occasional breakage on some models. Since there are many models and
! combinations that we have not tested, we would appreciate very much if
! you told us about things that work and do not work. To help us keep
! track of what hardware people, please mail your dmesg to
! <dmesg@openbsd.org>. If there are
! things that do not work, please file a bug report using
!
! sendbug(1).
