I think the magic word is "server".  But I don't remember if you 
   do a "set server yes" or "set xxx server". 
   
   ">>>set xxx foo" will usually give you an error message that tells 
   you the valid options for xxx are. 


"set server on" IIRC;  i had to do that with my /400 recently when finally
making it autoboot properly.  it was the final key :-)
