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.
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. New, greatly expanded VME bus support. A working install process that correctly creates a Motorola VID block on the disks.
The people working the most on OpenBSD/mvme88k are: Steve Murphree, Jr., and Miod Vallat. More would be nice :)
Email may be sent to the maintainer of the OpenBSD/mvme88k port at smurph@OpenBSD.org.
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.
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...
