Windows XP: PCI-based network adapters support wake from D3cold.

Note: Wake On LAN (WOL) support is not required in the following cases:

  • Bus-powered USB devices.

  • Multifunction, broadband (such as cable modems), LAN emulation, Wireless LAN, or Server LAN (such as multiport, FDDI, or Gigabit Ethernet) devices.

  • Windows 98/Me: PC Card and CardBus devices; WOL Pattern Match capabilities.

B7.1.5 General Network - FAQs

B7.1.5.1 Current Network Device FAQs

B7.1.5.2 NDIS status codes and indication mechanisms

See NdisMIndicateStatus in the Windows DDK.
B7.1.5.3 PCI network adapters for large-memory systems support the PCI DAC

[Server Design FAQs - SDG3:30-32]

Requirements for PCI adapters to support the PCI DAC command are defined in A1.1.6. For network devices, at a minimum this includes adapters implemented in or designed as high-speed network adapters -- Gb Ethernet and Gb , ATM, and FDDI -- for systems that support more than 4 GB of system memory. The exceptions to this requirement are 10/100 Ethernet adapters and embedded 10/100 Ethernet devices.

See "Large Memory Enabled Device Driver Hardware and Software Requirements" in the Windows DDK; design guidelines are summarized at

Requirements for systems that implement support for WinSock Direct (WSD) are now defined at A6.4.8. [For design guidelines, see SDG3:67]
