For online doc's, take this:

Ok, it's for a 3100/76, but the instructions are fairly accurate and, as
far as i can tell, valid for 4000/60 systems.

  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 
  Ah-hah! This one has HALT  set to 3. I haven't found any docs or online
 info
 about the nvram settings or post messages.
  Thanks, I'll try this.

            People disagree with me.  I just ignore them.
