      You should be able to get into ODT with no memory installed. Are you
      able to do that?

      The lights are only going to change if you're booting into ROM. Make
      sure about your DIP switch settings; personally, I'd just try to boot
      into ODT first and see if I get the prompt. I don't know if the boot
      ROM will do much without memory (it would be simple to try if mine
      were working, but the power supply is on the blink at the moment).
