<h3><font color=#0000e0><strong>History:</strong></font></h3>
<p>
The Motorola 88k processor is said to be the best RISC processor ever
devised. Its simplicity and elegance combine to make the mvme88k a
hearty, robust platform.
</p>
<p>
Nivas Madhur started the initial mvme88k port
for the MVME187 card, but has since moved on to another employer.
Steve Murphree, Jr. completed the port in November 1998. The port has
since had major changes including revamped autoconf and on-board SCSI
driver, greatly expanded VME bus support, working install
process that correctly creates a Motorola VID block on the disks,
and more boards supported.
</p>
<hr>
<a name=status>
<h3><font color=#0000e0><strong>Current Status:</strong></font></h3>
<p>
The people working the most on OpenBSD/mvme88k are:
Steve Murphree, Jr., and Miod Vallat.
More would be nice :)
</p>
<p>
Email may be sent to the maintainer of the OpenBSD/mvme88k port at
<a href="mailto:smurph@OpenBSD.org">smurph@OpenBSD.org</a>.
</p>
<p>
There is a snapshot available as of 2.4. The port supports the MVME187
Single Board Computer (SBC) as well as the MVME188 multi-processor board.
(only uses 1 processor currently) Support for the MVME197 is planned,
but time is needed to get things going. The installation tools and process
as of the 2.5 release actually work. OpenBSD/mvme88k can be installed or
upgraded via tape ramdisk images as well as network and diskless installs.
</p>
<h3><font color=#0000e0><strong>New for 2.8:</strong></font></h3>
<p>
<ul>
<li>Support for the MVME188 is complete.
<li>VME bus devices auto vector, providing a more 'plug and play' type environment.
<li>OpenBSD/mvme88k now uses the Unified Virtual Memory System. (UVM)
</ul>

<h3><font color=#0000e0><strong>Supported hardware list:</strong></font></h3>
<h4>OpenBSD/mvme88k runs on the following classes of machines:</h4>
<ul>
<li>MVME187: Motorola 88100 based Single Board Computer (SBC)
<li>MVME188: Motorola 88100 based VME systems<br>
The MVME188 CPU boards come in different flavours, differing by the number of
processors (1, 2 or 4) and associated CMMUs. All existing configurations should
be supported, but this has only been tested on 1P64 (1 cpu, 4 cmmu) and 2P256 (2
cpu, 4 cmmu) boards.
<li>MVME197: Motorola 88110 based Single Board Computer (SBC)
The MVME197 CPU boards come in different flavours, differing by the number of
processors (1 or 2) and the optional presence of an external cache controller.
All existing configurations should be supported, but this has only been tested
on a MVME197LE (no external cache controller) board. Support for this board is
new and it still has some 'features' to work out.
</ul>
<h4>Supported devices</h4>
<ul>
<li> Floppy drives:
<ul>
<li> SCSI floppy disk drives
</ul>
<li> Serial ports:
<ul>
<li> tty00, tty01, tty02 and tty03 on-board Cirrus Logic serial ports (MVME187)
<li> ttya and ttyb on-board DUART serial ports (MVME188)
<li> MVME332 8-port serial card
</ul>
<li> Ethernet adapters:
<ul>
<li> on-board Intel Ethernet (MVME187, MVME197)
<li> MVME376 AMD Lance Ethernet
</ul>
<li> SCSI controllers:
<ul>
<li> on-board "NCR" SCSI controller (MVME187, MVME197)
<li> MVME328 SCSI controller
</ul>
</ul>
<h4>Unsupported Devices. There are many more...</h4>
<ul>
<li>Disk Controllers:
<ul>
<li> MVME327 SCSI controller
</ul>
<li>Ethernet Controllers:
<ul>
<li> MVME374 LANCE controller
</ul>
<li>WAN Controllers:
<ul>
<li> MVME333 WAN controller
</ul>
</ul>
<hr>
<a name=projects>
<h3><font color=#0000e0>Project list:</font></h3>
<ul>
<li>Start work on device drivers for unsupported VME cards.
<li>Write code for new binutils (will fix ld bugs) and switch to ELF.
<li>Shared libraries.
</ul>

<h3><font color=#0000e0>mvme88k pictures:</font></h3>
<p>
The picture at the top of this page is a MVME 900 Series Chassis with a MVME187
33 Mhz, 32 Megabyte RAM SBC board, 4 MVME332XT serial boards and an
ARCHIVE 250 MB QIC Tape unit. Its hostname is m187. It is the primary build
machine for the OpenBSD/mvme88k port.

Check out the cool VME bus devices! Err, also check out how many builds
it took to get them working...
