For Plug and Play and power management support under Microsoft Windows operating systems, the system and its firmware must comply with Advanced Configuration and Power Interface Specification (ACPI).

ACPI firmware entries are the same for supporting all versions of Windows for x86 and x64 architectures. EFI firmware is required for 64-bit Windows on Intel Itanium-based systems.
