9 | In order to support very low power operation, the XO laptop uses a |
10 | secondary Display CONtroller, or DCON. This secondary controller | |
11 | is present in the video pipeline between the primary display | |
12 | controller (integrate into the processor or chipset) and the LCD | |
13 | panel. It allows the main processor/display controller to be | |
14 | completely powered off while still retaining an image on the display. | |
15 | This controller is only available on OLPC platforms. Unless you have | |
16 | one of these platforms, you will want to say 'N'. | |
