| 9 | If you have a network (Ethernet) card belonging to this class, say Y. | |
| 10 | Make sure you know the name of your card. Read the Ethernet-HOWTO, | |
| 11 | available from <http://www.tldp.org/docs.html#howto>. | |
| 12 | ||
| 13 | If unsure, say Y. | |
| 14 | ||
| 15 | Note that the answer to this question doesn't directly affect the | |
| 16 | kernel: saying N will just cause the configurator to skip all | |
| 17 | the remaining Blackfin card questions. If you say Y, you will be | |
| 18 | asked for your specific card in the following questions. | |
