| 60 | Also note that not all devices of the 43xx series support PIO. |
| 61 | The 4306 (Apple Airport Extreme and others) supports PIO, while |
| 62 | the 4318 is known to _not_ support PIO. |

| Michael Buesch | 77db31e | 2006-02-12 16:47:44 +0100 | [diff] [blame] | 64 | Only use PIO, if DMA does not work for you. |
