Power Management Support
The AT-2500 supports both Advanced Power Management
(APM) and Advanced Configuration and Power Interface
(ACPI) environments.
WAKE-ON-LAN (Remote System Wakeup)
----------------------------------
The AT-2500 Series provides Wake-On-LAN (WOL) capability,
WOL is used to remotely wake up a sleeping or powered off
PC on a network. This is accomplished by sending a specific
packet of information, called a Magic Packet frame, to a
node on the network. When a PC capable of receiving the
specific frame goes to sleep, it will enable the WOL mode
in the AT-2500 Series Adapter. When the LAN controller
receives a Magic Packet frame, it will alert the system to
wake up. A Magic Packet frame is simply a standard ethernet
frame containing the MAC address of the NIC in the system to
be awakened repeated 16 times.
APM and ACPI environments use different methods to respond
to a remote wake-up command. In an APM power-management
environment remote system wake-up is accomplished through
the system's APM-compliant BIOS and the AT-2500 hardware.
When the AT-2500 Series receives a Magic Packet(tm)
containing its MAC address it asserts the WAKEUP signal
through the external Wake-on-LAN cable to the system board.
APM power control logic then turns the system on and
intitiates the boot sequence. After the boot sequence the
APM-compliant BIOS clears the PME- signal, which resets
the WAKEUP signal so that subsequent wakeup events will
be detected.
In an ACPI environment remote system wake up is implemented
through the combination of an ACPI-compliant OS such as
Windows 2000 hardware that is compliant with the PCI
power management specification and the AT-2500 Series
hardware.
To enable Wake-On-LAN:
1. Install the AT-2500 Series in an available PCI
expansion slot.
2. Connect the WOL cable to the WOL connector on the
AT-2500 Series.
3. Locate the WOL connector on your system board.
4. Connect the other end of The WOL connector to your system
board WOL connector.
5. Ensure that the connectors are fully seated.
6. Check your system BIOS settings to ensure Power
Management and Wake on LAN features are enabled and set
correctly.
7. Enable Magic Packet support for the driver by changing
the Magic Packet setting under advanced options for the
driver.
NOTE: On Intel motherboards both the PME (Power Management
Event) and Wake on LAN BIOS options must be enabled.

Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
