    Don't forget that the Ethernet device gets configured when DECnet
is started, not before.  It's ESA0 on a VS2000...your MV2000 should
be the same.

    Also, on the back of the system box, above the power cable, is a
black switch with two positions: A and B.  Put the switch in the A
position if you want to use the ThinWire (BNC) connector, use the B
position if you're hooking to a transceiver connector.

    Here's "Table 2-2: Power-up and Self-Test Display Identifiers" from
my VS2000 hardware book:

--------------------------------------------------------------------------
Test Identifier	    Device
--------------------------------------------------------------------------
F		    Base Video
E		    System Clock
D		    Nonvolitile Random Access Memory (RAM)
C		    Serial Line Controller
B		    Memory
A		    Memory-management Unit
9		    Floating Point Unit
8		    Interval Timer
7		    Disk Controller
6		    Tape Controller
5		    Interrupt Controller and Ethernet ID ROM
4		    Optional 4-plane or 8-plane Graphics Coprocessor
3		    Reserved for later use
2		    Reserved for later use
1		    Ethernet Network Interconnect Module
--------------------------------------------------------------------------

Typical power-up error messages are:

1. Clock not set

	?  E  0040  0000.0005

2. Low battery

	?  D  0050  0000.0005

3. Monochrome monitor with 4-plane or 8-plane graphics coprocessor

	?  4  00D0  0009.0213

4. No Ethernet cable

	?? 1  00C0  0000.7004


The table of mnemonics for Test 50 is:
--------------------------------------------------------------------------
Mnemonics		Device
--------------------------------------------------------------------------
CLK			System Clock
4PLN			4-plane Graphics Coprocessor
8PLN			8-plane Graphics Coprocessor
DZ			Serial Line Controller
FP			Floating Point
HDC			Disk Controller
IT			Interval Timer
MEM			Memory
MM			Memory Mannagement
MONO			Monochrome Video Circuits on System Module
NI			Network Interconnect Option Module
NVR			Nonvolitile RAM
SYS			Interrupt Controller and Ethernet ID ROM
TPC			Tape Controller
--------------------------------------------------------------------------

Under the Test 0 (System Exerciser) description, which claims to take
11 minutes to complete, the manual states:

	Single question markls <in the output display> provide status 
	information and do not interfere with the operation of the
	system.

	Double question marks indicate errors.  Note the mnemonic asso-
	ciated with the question mark...
