  There have already been several good replys on changing the config,
etc; but there's one more little detail. If you have an old DN3000,
(pre May'87) the boot ROM won't know how to talk to the E-net card.
You need a revision 4.0 or newer boot ROM to work completely
properly with the E-net card.

  To check your boot ROM revision:
Shut down the machine, type in the "RE" command and <return> key twice.

  You can still use the E-net card in a DN3k with the old boot ROM,
it will work OK once the OS is booted, it is just that there will
be 2 problems. One is, if you remove the ATR card then the self test
diagnostics will fail. The machine will not auto-boot, you will have
to force it to boot by hand (give the "EX DOMAIN_OS" command).
The other is, you won't be able to use the E-net from the MD
(boot ROM) level. IE you cannot boot the machine diskless off another
Apollo on the E-net; you will always have to boot it off its internal
disk.
