   9 * The purpose of this code is to signal the operational status of a
  10 * target which usually boots over the network; while running in
  11 * PCBoot, a status LED is blinking. As soon as a valid BOOTP reply
  12 * message has been received, the LED is turned off. The Linux
  13 * kernel, once it is running, will start blinking the LED again,
  14 * with another frequency.
