17 | Advanced Configuration and Power Interface (ACPI) support for |
---|
18 | Linux requires an ACPI compliant platform (hardware/firmware), |
---|
19 | and assumes the presence of OS-directed configuration and power |
---|
20 | management (OSPM) software. This option will enlarge your |
---|
21 | kernel by about 70K. |
---|
22 | |
---|
23 | Linux ACPI provides a robust functional replacement for several |
---|
24 | legacy configuration and power management interfaces, including |
---|
25 | the Plug-and-Play BIOS specification (PnP BIOS), the |
---|
26 | MultiProcessor Specification (MPS), and the Advanced Power |
---|
27 | Management (APM) specification. If both ACPI and APM support |
---|
28 | are configured, whichever is loaded first shall be used. |

29 | |
---|
30 | The ACPI SourceForge project contains the latest source code, |
---|
31 | documentation, tools, mailing list subscription, and other |
