9 | Linux uses the PNPACPI to autodetect built-in | ||
10 | mainboard resources (e.g. parallel port resources). | ||
11 | |||
12 | Some features (e.g. real hotplug) are not currently | ||
13 | implemented. | ||
14 | |||
15 | If you would like the kernel to detect and allocate resources to | ||
16 | your mainboard devices (on some systems they are disabled by the | ||
17 | BIOS) say Y here. Also the PNPACPI can help prevent resource | ||
18 | conflicts between mainboard devices and other bus devices. | ||
