History:

The Motorola 88k processor is said to be the best RISC processor ever devised. It's 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.

Current Status:

The people working the most on OpenBSD/mvme88k are: Steve Murphree, Jr. More would be nice :)

Where to get it:

Supported hardware list:

OpenBSD/mvme88k runs on the following classes of machines:

• MVME187: Motorola 88100 based Single Board Computer (SBC)

Supported devices

• Floppy drives:
  • SCSI floppy disk drives
• Serial ports:
  • tty00, tty01, tty02 and tty03 on-board Cirrus Lodgic serial ports (MVME187)
  • MVME332 8-port serial card
• Ethernet adapters:
  • on-board Intel Ethernet (MVME187)
  • MVME376 AMD Lance Ethernet.
• SCSI controllers:
  • on-board "NCR" SCSI controller (MVME187)
  • MVME328 SCSI controller

OpenBSD/mvme88k does *not* run on these machines (yet):

• MVME188: Just a matter of time until I get a chassis for it
• MVME197: I can't seem to get one donated...

Unsupported Devices. There are many more...

• Disk Controllers:
  • MVME327 SCSI controller
• Ethernet Controllers:
  • MVME374 LANCE controller
• WAN Controllers:
  • MVME333 WAN controller

Where can you find hardware?

Project list:

• Start work on MVME197 port.
• Finnish work on MVME188 port.
• Start work on device drivers for unsupported VME cards.

mvme88k pictures:

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 baords and an ARCHIVE 250 MB QIC Tape unit. It's 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...
