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