OpenBSD/MACHINE OSREV runs on the following classes of machines:
	- MVME141 - Motorola with 68030 and 68882, with VSB interface
	- MVME147 - Motorola with 68030 and 68882
	- MVME162 - Motorola with 68040 and IndustryPack slots
	- MVME165 - Motorola with 68040, with VSB interface
	- MVME167 - Motorola with 68040
dnl 172 support is not tested
	- MVME172 - Motorola with 68060 and IndustryPack slots
	- MVME177 - Motorola with 68060

12MB of RAM should be sufficient to boot and a minimal system can probably
be squeezed onto a 250MB disk by installing only the `base' and `etc' sets.
However, a minimum of 16MB is necessary for the system not to be swap-bound,
with 32MB or more being recommended for serious usage of the system.
Note that until you have at least 32MB of RAM, getting more RAM is more
important than getting a faster CPU board.

Supported devices {:-include-:}:

MVME141:
	memory:
		both VME and VSB boards are supported, such as MVME224 boards
	serial ports:
		on-board ttyd0-ttyd1 - MC68681 (dart)
	VMEbus:
		supported

MVME147:
	serial ports:
		on-board ttya-ttyd (zs)
	Ethernet:
		on-board AMD 7990 Lance Ethernet (le)
	SCSI:
		on-board WD33C93 controller (wdsc)
	VMEbus:
		partially supported (some cards have issues)

MVME165:
	serial ports:
		on-board ttyd0 - ttyd1 - MC68681 (dart)
	VMEbus:
		supported

MVME162, MVME172:
	serial ports:
		on-board ttya-ttyd - Zilog Z85230 SCC (zs)
	Ethernet:
		on-board Intel 82596CA Ethernet (ie)
	SCSI:
		on-board NCR53c710 controller (osiop)
	VMEbus:
		drivers for short I/O access (untested)
	Flash:
		1MB flash, either Intel 28F008SA or 28F020
		A driver is available, but doesn't work correctly.
		Jumper GPIO3 selects Flash memory map and must
		be installed for booting with the Flash driver (default)
	SRAM:
		supported
	IndustryPack:
		untested

MVME167, MVME177:
	serial ports:
		on-board tty00 - tty03 - Cirrus Logic CD2401 (cl)
	Ethernet:
		on-board Intel 82596CA Ethernet (ie)
	SCSI:
		on-board NCR53c710 controller (osiop)
	SRAM:
		supported
	VMEbus:
		supported
		
Faithful clones of the above boards should also work.

Additional VMEbus devices:

	MVME327A SCSI and floppy Controller (vsbic), currently limited
	    to the SCSI interface only
	MVME328 High Performance SCSI Controller (vs)
dnl	MVME332XT High Performance Serial I/O Controller (vx)
	MVME376 Ethernet Communications Controller (le)
