1.3 fn 20: <p>
1.20 niklas 21: The alpha port was derived from the NetBSD/alpha port written by Chris
22: Demetriou <cgd@netbsd.org>. Unfortunately we cannot track it closely anymore
1.21 niklas 23: as some copyright issues prevent us, check our <a href=policy.html>policy</a>
1.22 deraadt 24: page for details. We are making our own efforts to keep this port modern,
25: which also includes many userland 64 bit problems which we have tracked down
1.29 deraadt 26: and made fixes to. Many of the improvements mentioned below are not found
27: in NetBSD, but you should do your own research to decide which those are.
1.14 niklas 28: <p>
29: Initially the reason for existence of this port was to provide the OpenBSD
30: operating system to alpha users, i.e. no special effort was put in to develop
31: the port in the machine dependent parts. The main thing that got done was to
1.17 niklas 32: ensure that all the tools needed to build a full system was included in the
33: tree, as well as updated with the changes Chris distributed in a separate
34: alpha toolchain package.
1.13 niklas 35: <p>
1.38 johns 36: Today a lot more developers have alpha machines and we are
1.23 niklas 37: seeing interest in a more active port. This fact has so far led to:
1.24 niklas 38: <ul>
1.29 deraadt 39: <li>A large-scale attack at fixing remaining 64-bit 'long' vs 'int'
40: problems in the entire userland source tree. Most of these
41: have been fixed, and new 64-bit problems are only rarely found.
1.38 johns 42: <li>Adaptation of the if_ed ethernet driver.
1.24 niklas 43: <li>Parsing of i386 MBR & disklabels.
1.27 deraadt 44: <li>DDB (kernel debugger) (disassembler, tracebacks, single stepping).
1.24 niklas 45: <li>IDE & ATAPI support.
46: <li>Easy installation via floppy.
1.30 kstailey 47: <li>Fixed VGA workstation console driver. Added "stand-out" (highlight) to it too.
1.24 niklas 48: </ul>
1.35 deraadt 49: <h3><font color=#0000e0><strong>Projects (in no particular order):</strong></font></h3>
1.24 niklas 50: <ul>
51: <li>ISA DMA (enables many common PC peripherals to be used)
52: <li>floppy support (requires ISA DMA).
53: <li>ELF object file format (gives shared libs)
54: </ul>
1.13 niklas 55: <p>
1.12 niklas 56: So far <a href="http://www.appli.se/niklas/">Niklas Hallqvist</a>
57: <a href=mailto:niklas@openbsd.org><niklas@openbsd.org></a> has been
58: keeping the port alive, but with the larger developer community coming up
59: this will hopefully be a more distributively (and better) maintained port.
