B2.5.3.2 - See B2.5.1.7 B2.5.4.1 Power management supported as defined in PCI Bus Power Management Interface Specification, Rev. 1.1 (PCI-PM)
PCI Bus Power Management Interface Specification, Revision 1.1, is the only industry specification that ensures compatibility with the power management capabilities of Windows, which uses PME# as the wakeup signal.
The primary PCI bus controller, PCI-to-PCI bridges, devices that implement PME# must comply with the PCI Bus Power Management Interface Specification, Revision 1.1. PCI add-on devices that do not implement PME# must comply with PCI-PM 1.0.

B2.5.4.1.1 System provides 3.3 V to all PCI connectors.
System supports 3.3 Vaux if the system supports S3 or S4 states for integrated devices that support waking the system and all PCI slots including MiniPCI.
System support for delivery of 3.3Vaux to the PCI bus must be capable of powering a single PCI slot with 375 mA at 3.3V and it must also be capable of powering each of the other PCI slots on the segment with 20 mA at 3.3V whenever the PCI bus is in the B3 state.
System support for delivery of 3.3Vaux to a PCI bus segment must be capable of powering a single PCI slot on that bus segment with 375 mA at 3.3V and it must also be capable of powering each of the other PCI slots on the segment with 20 mA at 3.3V whenever the PCI bus is in the B3 state.
In the case of systems with multiple PCI bus segments, delivering 3.3Vaux to one PCI bus segment does not mean that all PCI bus segments will be required to implement delivery of 3.3Vaux. However, if a system with multiple PCI bus segments provides 3.3Vaux to one or more segments and not to all segments in the system, these capabilities must be clearly marked and documented so that the end user can determine which slots support this capability. Examples of methods for indicating which slots support 3.3Vaux include icons silk-screened on system board sets, slot color-coding, and chassis icons.
Systems must be capable of delivering 375 mA at 3.3V to all PCI slots on a power-managed bus segment whenever the PCI bus is in any “bus powered” state: B0, B1, or B2.
B2.5.4.1.2 PCI add-on cards that use 3.3 Vaux operate correctly, using a method such as the one described in Section 7.4.4 of PCI-PM 1.1.
PCI add-on cards that use 3.3Vaux must operate correctly. This applies when the system supports 3.3Vaux to the PCI connectors.
B2.5.4.1.3 Bus power states are correctly implemented.
The PCI bus and all add-on capable devices on the PCI bus must comply with PCI Bus Power Management Interface Specification, Revision 1.1 or later. This includes correct implementation of the PCI configuration space registers used by power management operations, and the appropriate device state (Dx) definitions for the PCI bus and all add-on-capable devices on the PCI bus. ACPI is not an acceptable alternative.
