16 | Advanced Configuration and Power Interface (ACPI) support for | |
17 | Linux requires an ACPI compliant platform (hardware/firmware), | |
18 | and assumes the presence of OS-directed configuration and power | |
19 | management (OSPM) software. This option will enlarge your | |
20 | kernel by about 70K. | |
21 | ||
22 | Linux ACPI provides a robust functional replacement for several | |
23 | legacy configuration and power management interfaces, including | |
24 | the Plug-and-Play BIOS specification (PnP BIOS), the | |
25 | MultiProcessor Specification (MPS), and the Advanced Power | |
26 | Management (APM) specification. If both ACPI and APM support | |
27 | are configured, whichever is loaded first shall be used. | |
28 | ||
29 | The ACPI SourceForge project contains the latest source code, | |
30 | documentation, tools, mailing list subscription, and other | |
31 | information. This project is available at: | |
32 | <http://sourceforge.net/projects/acpi> | |
33 | ||
34 | Linux support for ACPI is based on Intel Corporation's ACPI | |
35 | Component Architecture (ACPI CA). For more information see: | |
36 | <http://developer.intel.com/technology/iapc/acpi> | |
37 | ||
38 | ACPI is an open industry specification co-developed by Compaq, | |
39 | Intel, Microsoft, Phoenix, and Toshiba. The specification is | |
40 | available at: | |
41 | <http://www.acpi.info> | |

205 | their lack of a BIOS setup menu and APM support. | |

208 | ACPI. This driver is required for access to controls not covered | |
209 | by the general ACPI drivers, such as LCD brightness, video output, | |

213 | under "Processor type and features") in several aspects. | |
214 | Configuration is accessed by reading and writing text files in the | |
215 | /proc tree instead of by program interface to /dev. Furthermore, no | |
216 | power management functions are exposed, as those are handled by the | |
