|  | and read the Ethernet-HOWTO, available from | 
|  | <http://www.tldp.org/docs.html#howto>. | 
|  |  | 
|  | Note that the answer to this question doesn't directly affect the | 
|  | kernel: saying N will just cause the configurator to skip all | 
|  | the questions about WIZnet devices. If you say Y, you will be asked | 
|  | for your specific card in the following questions. |
