SUMMARY - Help...Dead Headless SS1

  Thanks for the responces. But the jest of the request seems to have been
  I was looking for a way to force it back without attaching a terminal.
  Solutions :
  1) #1 responce, and the most obvious (even to me, really!); attach a terminal.
  2) 3- "Reset the EEPROM". There was no description of how to do this, so I
have no clue how it is done. I assume this is either an "Urban Legend", or
involves chip pullers and bailing wire.
  3) 1- Don't set "input_device=ttya" or "output_device=ttya" in the first
place. Again, not much help now, but I suppose it made them feel better. The
Sparc Station will default to Input/Output_device=ttya if no keyboard or
video card is installed.
  4) 0- Once the terminal is attached, and the system is booted, there is no
way to <L1> A. I found that there is an "eeprom" command that will set the
EEPROM values as required. After they are set, you have to power cycle the
machine to take effect. I suppose you could "halt" and then manage them that
way too. I believe there has to be kernal support enabled for this to work.
  5) One or two responces sugested <L1> N to reset the EEPROM, but without
the machine watching the keyboard in the first place, and the terminal not
having an <L1> equlivant, that was not possible.
