### केर्नल विकल्प: एसिपिआई

ACPI (Advanced Configuration and Power Interface) is a standard that defines power and configuration management interfaces between an operating system and the BIOS. By default, एसिपिआय is switched on when a BIOS is detected that is newer than from year 2000. There are several commonly used parameters to control the behavior of ACPI:

- पिसिआई=एनओ -- do not use ACPI to route PCI interrupts
- एसिपिआई=ओल्डबूट -- only the parts of ACPI that are relevant for booting remain activated
- एसिपिआई=ओफ -- switch off ACPI completely
- एसिपिआई=फोर्स -- switch on ACPI even if your BIOS is dated before 2000

Especially on new computers, it replaces the old एपिएम system.
