9 | If you have a network (Ethernet) card belonging to this class, say Y. | |

11 | If unsure, say Y. | |

13 | Note that the answer to this question doesn't directly affect the | |
14 | kernel: saying N will just cause the configurator to skip all | |
15 | the remaining Blackfin card questions. If you say Y, you will be | |
16 | asked for your specific card in the following questions. | |
