                     17: <hr>
                     18: <h3><strong>History and Status:</strong></h3>
                     19:
                     20: <p>
                     21: The early history is not very clear. Apparently the first work was
                     22: done by CMU as part of their Mach project.  The initial hardware was
1.26      pefo       23: the DEC R2000/R3000-based DECstations.  This code was later used by
1.1       deraadt    24: both the Sprite and BSD groups.  The 4.4BSD code, known as the `pmax'
                     25: port, was made freely available in mid '93.  It was merged into the
                     26: NetBSD tree by a variety of people, but has never been very stable,
                     27: reliable, or complete.  Compiler toolkit problems have plagued the
                     28: port because the standard a.out executable format is an imperfect
                     29: match to the MIPS architecture.
                     30: </p>
                     31:
                     32: <p>
1.9       niklas     33: Per Fogelstr&ouml;m became familiar with the code after porting it to a
1.1       deraadt    34: home-built IDT R3081 based board.  Subsequently he added R4400 support
                     35: when porting it to the MIPS R4400 Acer PICA board.  Willowglen
                     36: Singapore purchased a second PICA board for Theo de Raadt so that he
                     37: could improve the port for use as a development system for an internal
1.20      imp        38: project.  Since then Theo, Per and others have completed the port.
1.1       deraadt    39: </p>
                     40:
                     41: <p>
                     42: The Acer PICA is a dead platform.  Acer no longer makes the machine,
                     43: but even worse the machines are very rare.  But the Acer PICA was just
                     44: one of a whole family of similar machines built by other companies
1.28      imp        45: like MIPS, Deskstation, NEC, Olivetti.  These machines were known as
1.33      imp        46: ARC machines, built according to the
                     47: <a href="http://www.microsoft.com/hwdev/download/respec/riscspec.zip">
                     48: Advanced RISC Computing</a> specification.
1.15      imp        49: No new ARC BIOS machines for MIPS will likely be manufactured.
                     50: Microsoft has announced that it will no longer support MIPS after NT 4.0.
1.24      todd       51: OpenBSD/arc provides a good alternative to NT, especially now that no more OS
1.34    ! imp        52: updates for NT MIPS will happen.  Deskstation has ceased business operations,
        !            53: so there will be no more ARC MIPS machines from them.

                     56: <p>
                     57: As a result, the code has been modified to make it more versatile, and
                     58: eventually it should support a larger whole range of ARC machines.
                     59: Hopefully a port will result that can run on the full range of MIPS
1.33      imp        60: processors: R4000, R4xx, R43xx, R4400, R46x0, R4700, R5000,
