Adding second ethernet interface to DS5000

[P. Attfield]

Hi;
	I have just completed the addition of a thick-ether option card
to a DECstation 5000 (Ultrix 4.0) and am searching for the required mods to the
config file. I have added the addition of "device ln1 at ibus? vector
lnintr" to
the config file and encounter the following problems:

1) su
 - is killed on unaligned access

2) login as root
 - gives a bizarre message in the upper-left corner of the screen
(/dev/ttyp) and
   the login never completes. By logging in across the net I have been
able to su
   and kill the x-server (oh yes, this 5000 features a 2D accelator)
after which
   things work relatively sanely providing you are not root.

NOTE: I have added a dummy ifconfig for ln0 (the thin-ether interface) and have
      ifconfig'd it to down (this is described in the Ultrix 4.0 release notes,
      section 2.12.5) to no avail. 

      The new ethernet device successfully finds the net, but something
is getting
      confused. Also, the thin port is terminated (with the tee).

Is there something else that needs to be done to the config file ??
Please advise.
