| 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> |
