Power Management and Delivery
The 82574 supports the Advanced Configuration and Power Interface (ACPI 2.0)
specification as well as Advanced Power Management (APM). This section describes
how power management is implemented in the 82574.
Implementation requirements were obtained from the following documents:
Assumptions
The following assumptions apply to the implementation of power management for the
82574.
