Hello,

Just my 2 cents:

It's only the 4000/9x that gets so confused by the NetBSD booter that it
won't boot unattended anymore. It will throw a "SYS"-error (0200).

My 4000/60 is happy with NetBSD, booting all the way to whatever OS i
throw at it. Just don't POWER DOWN your terminal while connected.
This will be interpreted as a break on the console line, which throws
you into the console monitor, just like a HALT.
Disconnect your terminal.
As a proof, this email is sent to the list via my 4000/60, running
NetBSD without a console terminal attached. (Some proof, i know ... 8-)
The 4000/vlc works just as well.

To get the 4000/60 autobooting you have to have

        SET BOOT dka0 (or whatever your system disk is)
        SET HALT 1
        SET BFLG 0

Most NetBSD's up to 1.5.2 garble the "HALT" setting on shutdown, so you
should check this ("SHOW HALT"). Valid values are:

        3: Machine halts on powerup (Manual boot)
        2: Automatic reboot
        1: Automatic restart
        0: same as 2

"Automatic restart" is usually the default, since it tells the VAX to
try to quickly recover from e.g. a power failure. Try 0 or 2 as well.

If all this does not help, you might have a dead battery. But you should
get some error on powerup then.

Hope this helps
