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. | |
