attempting to update firmware on a flash memory Omni or Lumina controller, the
update begins and the flash is erased. When the update begins, it proceeds for
a few seconds, then stops and in a small box, a Not an Ack message is displayed.
Check the jumpers under the U29 chip socket. Jumper JP10 should cover the
center and right hand pins. Jumper JP15 should cover both pins.
