I have tried again with the 1.11.2 booter, but the same problems
occur. However, I seem to have isolated the problem.

In the booter options it lets you change your screen resolution and
colour depth. If these options are disabled, and I change my monitor
depth to B&W in the Monitors control panel, then everything works
ok.

However, if the 'Change depth to: B&W' option is checked, then it
will crash. The symptoms:

    - changes bit depth to B&W
    - still displaying MacOS, it crashes:
        - the screen is shrunk to about 1/4 size and repeated in
        one horisontal row 4 times across the screen, and a bomb
        box (which is very tiny) is displayed. I would estimate
        it is trying to show 21 inches of image in about 5 inches.
        - trying the panic button DOES work, but it uses the
        extremely tiny-weeny resolution. I was able to do
        'sm 0 a9f4 RETURN g 0 RETURN' (force quit), and then it
        was working ok except it was still tiny.

This is a IIvx with a single Apple 2-page greyscale display (on
the IIvx that means 16 greys) with matching nubus card. Virtual
Memory is off, 32bit addressing is on.

Is having localtalk disabled important? I have a LaserWriter
Plus, which needs localtalk, but the printer is the only thing
connected. It never caused any problems under 7.1 (not that I
was networking netbsd to anything anyway).

TIA,
Andrew
