| 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. |
