An odd place to hang.  Did you change the /etc/ttys file a la (note the bit
about this only being necessary for multi-user mode - single user will boot
without this):

3.) Change the "/etc/ttys" file.  It can be moved to the MacOS disk via
    the minishell's "cpout" command:

      cd /etc
      cpout ttys ttys

    Edit it, changing the lines:

      # Define console that we actually run getty on
      ttye0 "/usr/libexec/getty Pc" vt220 on secure

    and:

      #Hardwired lines are marked off ...
      tty00 "/usr/libexec/getty std.9600" unknown off secure

    to:

      # Define console that we actually run getty on
      ttye0 "/usr/libexec/getty Pc" vt220 off secure

    and:

      #Hardwired lines are marked off ...
      tty00 "/usr/libexec/getty std.9600" unknown on secure

    respectively.  Save this file as text with Unix line terminations
    and "cpin" it back to "/etc/ttys":

      cpin ttys ttys

    Without this step, the kernel will boot only into single user mode
    when this is selected in "Booter".

The above  is from a How-To I wrote on getting the Classic II to work
(though I should point out that I'm ignorant about NetBSD and the how-to
just contained the distilled wisdom of others, no-doubt with errors
introduced by me).  Look it up in the list's archive.  The "for_mays" seems
a little less stable than "GENERIC#5" on the Classic II.

I am just starting to look at why the Classic II doesn't boot with internal
video with the ADBTEST kernels.  It seems that the screen is at 0x009F9A80
to 0x009F000 (as set by the EAGLE chip), but NetBSD doesn't know this -
just my first theory, so it's probably wrong.  Any comments?  Don't hold
your breath for any developments.  (I'm hoping that the EAGLE, being mainly
just a switching gateway, doesn't need any special setting up - what other
Macs use this chip and do I need to worry about it?)

Yours,

Andrew
