# Remote Wake-Up and Wake-On-LAN (WOL)

## Microsoft* Windows Products

Microsoft* Windows NT* and Windows 95 are not ACPI-capable. Some settings are not available in these operating systems.

Microsoft Windows 98, Windows Me, Windows 2000, Windows XP*, and Windows Server 2003 for 32-bit systems are ACPI-capable. These operating systems do not support wake from S5 state, only from standby. When shutting down the system, they shutdown ACPI devices including the Intel PRO adapters. This disarms the adapters remote wake up capability. However, in some ACPI-capable computers, the BIOS may have a setting that allows you to override the OS and wake from an S5 state anyway. If there is no support for wake from S5 state in your BIOS settings, you are limited to Wake From Standby when using these operating systems in ACPI computers.

The advanced tab in the Intel® PROSet software includes a setting called Enable PME for some adapters. To explicitly allow wake up with a Magic Packet from shutdown under APM power management mode, set this to Enable. See Intel PROSet online help for more details.

In ACPI-capable versions of Windows, the Intel PROSet advanced settings also include a setting called Wake on Settings. This controls the type of packets that wake up the system from standby. See Intel PROSet online help for a complete explanation.

In ACPI computers running ACPI-aware operating systems such as Windows 2000, make sure the wake on standby option is enabled. To enable wake on standby, open the Device Manager and then navigate to the adapter properties tab Power Management. Check the setting “Allow this device to bring the computer out of standby”.

| NOTE: The Legacy OS Wakeup Support feature is not available in early versions of the Intel® Boot Agent. To update your Boot Agent to the latest version, download 100PBOOT.EXE from the support website and follow the included instructions.
