1.1 deraadt 19:
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
26: and made fixes to.
1.14 niklas 27: <p>
28: Initially the reason for existence of this port was to provide the OpenBSD
29: operating system to alpha users, i.e. no special effort was put in to develop
30: the port in the machine dependent parts. The main thing that got done was to
1.17 niklas 31: ensure that all the tools needed to build a full system was included in the
32: tree, as well as updated with the changes Chris distributed in a separate
33: alpha toolchain package.
1.13 niklas 34: <p>
1.12 niklas 35: Today a lot more developers have got themselves alpha machines and we are
1.23 niklas 36: seeing interest in a more active port. This fact has so far led to:
1.24 niklas 37: <ul>
38: <li>Adaption of the if_ed ethernet driver.
39: <li>Parsing of i386 MBR & disklabels.
1.27 deraadt 40: <li>DDB (kernel debugger) (disassembler, tracebacks, single stepping).
1.24 niklas 41: <li>IDE & ATAPI support.
42: <li>Easy installation via floppy.
1.26 kstailey 43: <li>Fixed VGA workstation console driver.
1.24 niklas 44: </ul>
1.23 niklas 45: <h3><strong>Projects (in no particular order):</strong></h3>
1.24 niklas 46: <ul>
47: <li>ISA DMA (enables many common PC peripherals to be used)
48: <li>floppy support (requires ISA DMA).
49: <li>ELF object file format (gives shared libs)
50: </ul>
1.13 niklas 51: <p>
1.12 niklas 52: So far <a href="http://www.appli.se/niklas/">Niklas Hallqvist</a>
53: <a href=mailto:niklas@openbsd.org><niklas@openbsd.org></a> has been
54: keeping the port alive, but with the larger developer community coming up
55: this will hopefully be a more distributively (and better) maintained port.
