-+OpenBSD/mvme88k is an effort to port OpenBSD to the Motorola's 881x0-based +VME motherboard family. +
+ ++There is currently no maintainer for the mvme88k port, as it is not +officially supported. +The people working on it are +Steve Murphree and +Miodrag Vallat. +

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, greatly expanded VME bus support, working install -process that correctly creates a Motorola VID block on the disks, -and more boards supported. +Nivas Madhur started the initial mvme88k port for the MVME187 card, but +has since moved on to another employer. +The port was brought in the OpenBSD tree by Dale Rahn, but he did not +have enough time to work on it. +Steve Murphree, Jr. eventually completed the port to the MVME187 in +November 1998.
--The people working the most on OpenBSD/mvme88k are: -Steve Murphree, Jr., and Miod Vallat. -More would be nice :) +Unfortunately, at the same time, a compiler upgrade from gcc 2.8.1 to +egcs revealed a lot of problems in the mvme88k support in gcc, which +could not be fixed in time for mvme88k to be a supported OpenBSD 2.5 +release. +As of today, these problems are still not entirely fixed.
-Email may be sent to the maintainer of the OpenBSD/mvme88k port at -smurph@OpenBSD.org. +The lack of an in-tree toolchain did not prevent further work on the port, +and a lot of changes were made to the codebase, such as 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 support for MVME188 as well as improving support for MVME197.
+-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 development of this port is currently stalled, while people are busy +dissecting the mvme88k back-end of gcc and fixing the code generation errors.

+Due to the compiler problems, no snapshots have been generated since a long +time. There was a 2.4-current snapshot on the ftp mirrors for some time, which +supports only MVME187 cards and can be used as a very crude basis to rebuild +a complete system, for the adventurous hacker. If you want to get it, ask +miod. Access to an OpenBSD/mvme68k +system greatly helps, as both systems are very similar. +
+-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. +As VME hardware is quite uncommon in the average retail place, and Motorola +881x0-based hardware is even more rare, this section is here to satisfy the +well-founded curiosity about the mvme88k hardware.

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