Notes on Supported Boards
Contents
These are the Motorola Single Board Computers that NetBSD/mvme68k
supports.
These are the other supported VMEbus boards that NetBSD/mvme68k
supports.
CPU-specific support for the MVME147 family of Single Board Computers
was written by Chuck Cranor.
Supported Hardware
Initially introduced in 1988, the
MVME147 family
is Motorola's oldest Single Board Computer (SBC) product. It was
the first VME board with integrated networking, serial communications,
mass storage interface, and parallel port. This VMEbus SBC is
based on the MC68030 microprocessor.
NetBSD/mvme68k runs on Motorola MVME147 boards, with as little
as 4MB of RAM, though 8MB or more is recommended. Note: A bug
in the boot code for releases <= 1.3.2 causes problems on 4Mb
boards. This has been fixed in -current and 1.3.3 onwards.
Nearly all of the on-board MVME147 hardware is supported:
- Battery-backed real-time clock
- Network interfaces
- on-board Lance AM7990 Ethernet
- Parallel port
- on-board Centronics style printer port
- SCSI (most disks, tapes, CD-ROMs, etc)
- on-board Western Digital wd33c93 SCSI bus interface chip
using DMA facilities of the board (asynchronous SCSI only)
- Serial ports (RS232)
- on-board Zilog Z8530 dual serial controller
- built-in console and tty01 - tty03, with speeds up to 38400 baud
- VMEbus
- all VMEbus boards supported by NetBSD's machine-independent
VMEbus framework. See /sys/dev/vme for details.
The following on-board hardware is not yet directly supported by
the kernel:
- NVRAM (reading and writing)
NetBSD/mvme68k also fully supports VMEbus RAM cards in both A24/D32
and A32/D32 address spaces. (Note: On MVME147s with < 16Mb
of internal RAM, access to A24/D32 space is restricted. There is
no A24/D32 access on MVME147s with >= 16Mb internal RAM.)
Known Bugs for the MVME147 port:
- Due to a design flaw on the board, adding VMEbus RAM will
actually slow the system down! This is caused by the
hardware forcibly disabling the CPU's cache on VMEbus
accesses. Work is in progress in NetBSD-current to prioritize
memory segments so that faster memory is allocated first,
in preference to slower memory. This should help improve
performance of systems using VMEbus RAM.
Board-specific support for the MVME162 was written by Steve Woodford.
Supported Hardware
The second generation
MVME162 family
and
MVME172 family
Single Board Computers are based on the MC68040/MC68LC040 and
MC68060/MC68LC060 microprocessors.
These second generation SBCs offer faster processors and additional
on-board memory capability.
NetBSD/mvme68k 1.5 runs on Motorola MVME162 boards, with as little
as 4MB of RAM (with the help of a VMEbus RAM card), though 8MB or more
is recommended.
NetBSD/mvme68k -current runs on Motorola MVME172 boards.
The major parts of the on-board MVME162 and MVME172 hardware are supported:
- Battery-backed real-time clock
- Network interfaces
- on-board Ethernet Intel i82596 controller
- SCSI (most disks, tapes, CD-ROMs, etc)
- on-board NCR 53c710 SCSI bus interface chip
using DMA facilities of the board supporting synchronous transfers
up to 10 Mbytes/second.
- Serial ports (RS232)
- on-board Zilog Z85230 communications controllers
- built-in console and tty01 - tty03, with speeds up to 38400 baud
- VMEbus
- all VMEbus boards supported by NetBSD's machine-independent
VMEbus framework. See /sys/dev/vme for details.
- MEMC040 (onboard memory controllers)
The following on-board hardware is not yet directly supported by
the kernel:
- NVRAM (reading and writing)
- IP Controllers (Industry Pack sites)
Known Bugs for the MVME162 MVME172 boards:
Board-specific support for the MVME167 and MVME177 was written
by Steve Woodford.

NetBSD/mvme68k 1.4 runs on Motorola MVME167 boards, with as little

Known Bugs for the MVME167 and MVME177 boards:
Any VMEbus RAM board which does not require software to set it
up should work with MVME147 cards. At this time, VMEbus RAM boards
are not officially supported with other MVME boards.
These VMEbus RAM boards are known to work the NetBSD/mvme68k.
The list of VMEbus RAM boards known to work is currently
under development. If you have a VMEbus RAM board that works
with NetBSD/mvme68k please send the model number to
www@NetBSD.org.
It will be added to the list.
These transition boards are compatible with the MVME147, MVME167 and
MVME177 family of single board computers.
- MVME712A
- MVME712B
- MVME712-012

- MVME712AM
- MVME712M
- MVME712-013

These are some general comments that apply to NetBSD/mvme68k.
- Application code for any m68k-based NetBSD platform will
run on all the mvme68k single-board computers without change.
- If necessary, a single kernel image can be built which
will boot on all the MVME models.
