| ebd4bfee DC |
13 | Handheld devices from One Netbook and Aya Neo provide fan readings and fan |
| 14 | control through their embedded controllers. | |
| ed264e8a | 15 | |
| ebd4bfee DC |
16 | Currently only supports AMD boards from One X Player, AOK ZOE, and some Aya |
| 17 | Neo devices. One X Player Intel boards could be supported if we could figure | |
| 18 | out the EC registers and values to write to since the EC layout and model is | |
| 19 | different. Aya Neo devices preceding the AIR may not be supportable as the EC | |
| 20 | model is different and do not appear to have manual control capabilities. | |
