RE: OT: WOL

["Paul Gordon" <paul_gordon@xxxxxxx>]

Generally, WOL responds to the "Magic packet"...

which is a packet that contains 16 contiguous copies of the receiving
network adapter's Ethernet address.

Presuming you are only talking about Windows OS's, then:

For implementation guidelines, see items #34 – 35 in the “Network
Communications” chapter of PC 97 Hardware Design Guide. Implementation
details are described in “Network Wake-up Frames” and “Network Wake-up
Frame
Details” in Network Device Class Power Management Reference Specification,
Version 1.0 or higher.

If it is specificallyn Windows 2000 then:

The Windows 2000 WakeOnLAN feature can be enabled or disabled on a network
adapter. It is a completely on or completely off binary feature. If the
network
adapter supports power management, WakeOnLAN can be enabled on the Power
Management tab in the network adapter properties by clicking to select the
"Allow this device to bring the computer out of standby" check
box. When
enabled, all network adapter programmed packet patterns wake up the
computer.
When disabled, no packet patterns wake up the computer.

With the following fix in place and a registry change, WakeOnLAN can be
enabled
only for "magic" packet patterns.

To enable the WakeOnLAN feature for all patterns, select the check the box
that
enables WakeOnLAN, the same as before.

To enable WakeOnLAN only on magic packet patterns, select the check the box
that
enables WakeOnLAN and alter the registry setting (by using the .inf file as
described in the "Resolution" section) that narrows the patterns
to just
magic
packet patterns.
