On hardware platforms that have an ACPI BIOS, the HAL causes to be loaded during system startup at the base of the device tree.

Checked versions of the Windows ACPI driver, Acpi.sys, contain a debugger component to support AML debugging.

For more information about the AMLI debugger, see ACPI Debugging.

ACPI control methods are software objects that declare and define simple operations to query and configure ACPI devices.

Control methods are stored in the ACPI BIOS and are encoded in a byte-code format called ACPI Machine Language (AML).

For drivers loaded on ACPI-enumerated devices, always implements the physical device object (PDO) in the driver stack.

For more information, see Evaluating ACPI Control Methods. Revision 5.0 of the ACPI specification introduces a set of features to support low-power, mobile PCs that are based on System on a Chip (So C) integrated circuits and that implement the connected standby power model.

Not all motherboard devices have an ACPI bus filter.

All ACPI functionality is transparent to higher-level drivers.

For each device described in the ACPI namespace hierarchy, the Windows ACPI driver, Acpi.sys, creates either a filter device object (filter DO) or a physical device object (PDO).

If the device is integrated into the system board, creates a filter device object, representing an ACPI bus filter, and attaches it to the device stack immediately above the bus driver (PDO).

Starting with Windows 8 and Windows 8.1, the Windows ACPI driver, Acpi.sys, supports the new features in the ACPI 5.0 specification.
