Did you take the sample token ring entry out of /etc/net?
I suppose you know by now, but I doubt that your baseband adapter's
jumpers are the whole problem.  I don't think you'd be able to
talk to the net at all with default settings on both the card and
in the software.

The card comes jumpered to use memory starting at 98000 hex; the default
in /etc/ddi (used by devices) is 80000.

They get along fine here.  I don't know anything about XONDOS.

What's in your /etc/.init.state file? It should be one character (and a
newline), probably `a' for `automatic multi-user' or `m' for `maintenance'
(single-user mode).  This letter gets passed as an argument to /etc/rc
to determine the run level on boot.  Documented in chapter 3 of the
Operating System Technical Reference (assuming you're running an RT).

Not me.  Our systems are fast and reliable.  The Berkeley stuff that's
been integrated into the system is really a part of it, not a pile
of scabs and patches, and it's true to the way the stuff works on
BSD-based systems (except for symbolic links, but I don't really
want to get into that now... ).

Things to do to get a network node going:

- Edit /etc/hosts.  You don't need a `localhost' entry for loopback;
  the local system is just another name in the list.

- Edit /etc/hosts.equiv.

- Edit /etc/rc.tcpip (to set the host name at boot time)

- Edit /etc/rc to uncomment the invocation of /etc/rc.tcpip

- Edit /etc/net.  Comment out or remove the token ing entry unless
  you're running token ring.

- Run `devices' to add net0 (driver for the baseband adapter).

- Use the `devices' command to make ptys, some with gettys and some
  without.  If you need more than 16 ptys, bump the value of
  `ptybuffers' in /etc/master and make a new kernel, and edit
  /etc/ddi/pty to make more blank entries for use by devices.  IBM
  people say they're going to provide a batch program to create
  devices; for now, it's all interactive and somewhat tedious.

- To run X on an RT, you need at least 8 megs of memory.
  For running X, there are some resource limits in the
  kernel that should be bumped upward.  The ones I changed were

	ptybuffers  (from 16 to 32)
	charlists (64 to160)
	maxminor (in the `uptc' and `upts' stanzas; 16 to 32)
	procs (in `sysparms'; 60 to 90)
	filetab (250 to 350)
	inodetab (250 to 350)
