================================================================
Note: the information in this file applies to Intel management adapters
only. Standard, non-management adapters do not have a 3-pin auxiliary
power connector.

Wake on LAN
===========
Description
The Wake on LAN (WOL) feature of the PRO/100+ Management adapter allows
a Wake on LAN enabled computer to be powered-on remotely by a network
management program. In some operating systems, it can also wake the
computer from suspend mode. This is accomplished by sending a special
type of data packet containing the adapter's specific Ethernet address.
The PRO/100+ Management adapter is supplied with a small cable with a 3
pin connector at each end. One end of the cable is attached to the
adapter, and the other end is attached to the 3 pin WOL connector on the
WOL enabled computer. As long as AC power is available to the power
supply, the adapter will draw +5 volt standby power through the cable
when the machine is powered off, allowing it to "listen" to the network
for a wake up packet. If the cable is not attached, the Wake on LAN
function will not be available and the adapter will operate as a
standard non-management PRO/100+ adapter.
Computer requirements
Only a computer designed for Wake on LAN can use this function. It must
have a 3 pin connector that matches the 3 pin cable supplied with the
PRO/100+ Management adapter. If the computer has a Wake on LAN
connector that does not fit the 3 pin cable, do not attempt to use it
with this adapter. Attempting to do so could cause permanent damage to
the computer.
The +5 volt standby power supply must be capable of supplying at least
0.6 amps (600 milliamps) at +5 volts. This value is usually listed on
the power supply label as +5SB, +5VSB or +5AUX.
WOL Settings in Microsoft Windows* 98
If the PRO/100+ Management adapter is installed in Microsoft Windows 98,
you will have an additional setting in the adapter properties that is
not available for other types of PRO/100+ adapters. This setting is
titled "ACPI Wake On LAN" and by default is set to "Enabled". You may
need to change this setting to "Disabled" if you are using the PRO/100+
Management adapter in a Wake on LAN enabled computer that is not ACPI
compliant. Check your computer owner's manual or contact your computer
vendor to determine if your computer is ACPI compliant.
Settings in the computer's BIOS
Wake on LAN enabled computers typically have settings similar to the
following:
On Modem Ring Stay Off
On LAN Power-on
On PME Stay Off
The setting "On LAN" refers to wake-up events received through the 3 pin
WOL connector. The setting "On PME" refers to wake-up events received
through a signal on the PCI bus defined as "Power Management Event". The
PRO/100+ Management adapter is capable of using either of these methods.
Which settings to use will vary with the computer and operating system.
The following are suggestions only.
A. In ACPI compliant computers running Windows 98, set the "On LAN" BIOS
setting to "Stay off" and the "On PME" BIOS setting to "Power-on".
In other operating systems, or in computers that are not ACPI
compliant, set the BIOS setting "On LAN" to "Power-on" and the BIOS
setting "On PME" to "Stay Off".
B. If these settings do not work for you, try reversing them, or set
both to "Power-on".
Troubleshooting Wake on LAN
Note: The reception of a wake up packet will set the adapter to a
special state. This condition must be reset before the adapter will
accept another wake up packet and power-on the computer. The drivers for
this adapter are written to reset this condition when they load. The
only other way of resetting this condition is removing AC power from the
computer for a short duration (~10 seconds). Once you have sent the
computer a wake up packet and powered-on the computer, you must let a
driver load or it will no longer accept any wake up packets. If this
happens, you can remove the AC power cord for 10-15 seconds or load an
adapter driver to reset the adapter and restore normal operation.
If the computer will not power-on when a wake up packet is sent, check
the computer's BIOS for power settings (see "Settings in the computer's
BIOS" above).
If you are connected to a hub or switch, the link LED on the back of the
adapter should be on, even though computer power is off. If the link
LED it is not on, try powering the computer on. If the LED now lights,
then the adapter is not receiving power in standby mode. If this is the
case, check to make sure the 3 pin cable is properly plugged into a
standard WOL 3 pin connector. Make sure that the power supply is capable
of supplying the necessary current (see Computer Requirements above).
Also, check with your computer vendor to be sure that the computer is,
in fact, capable of supporting Wake on LAN.
If the link LED does not come on when the computer is powered-on, you
have not established link with your hub or switch. Check your cabling or
substitute a known good cable. Make sure your hub or switch is either
10baseT or 100baseTX and is powered-on and fully functional.
If your computer will not power-on at all when the 3 pin cable is
attached, but will power-on when the 3 pin cable is removed, your +5
volt standby power supply is possibly insufficient (see Computer
Requirements above).
If everything listed above is correct and the computer will still not
respond to a wake up packet, check with your computer vendor for an
updated BIOS.
Intel LANDesk Service Agent (LSA)
=================================
Description
The LSA is a utility program that is stored in a flash memory chip on
the adapter. This utility will execute when the computer is first
powered-on. It will attempt to obtain an IP address from a DHCP or BOOTP
server and locate a program image file to download and execute. This
feature is intended for use in conjunction with network management
software (such as Intel LANDesk products) to automatically configure
newly installed computers.
Computers do not need to be Wake on LAN enabled to use this feature, and
it will work with or without the 3-pin auxiliary power connector
attached.
Operation
When the LSA executes, you should first see the message "PXE-M04 Hooking
Bootstrap Interrupt 19h" appear on the screen. After this times out, it
should then attempt to locate a DHCP or BOOTP server. If it can not
locate a DHCP or BOOTP server or cannot locate an image file to
download, it should time out and the computer should continue to boot
normally. If it does download an image, you may be presented with
additional options. This sequence can be manually interrupted by
pressing Escape or CTRL-C.
The LSA can use bootstrap interrupt 18h or 19h. To change the interrupt,
press Ctrl-T when the message "PXE-M04 Hooking Bootstrap Interrupt 19h"
appears on the screen. This change will be automatically saved to the
adapter. If you are not using the correct bootstrap interrupt for your
computer, it will boot from the next available boot device immediately
after the "PXE-M04" message times out. The bootstrap interrupt is not
related to the hardware interrupt (IRQ) assigned to your adapter.
Troubleshooting LSA
If you do not see the message "PXE-M04 Hooking Bootstrap Interrupt 19h",
check the following;
In the computer setup, check for the boot device sequence. If "LANDesk
Service Agent" or "Network" is listed, move it ahead of the hard drive
in the boot sequence.
Some computers require manual intervention to execute the LSA. Look for
an informational note on the computer monitor after power-on that may
instruct you on executing a network boot. For example, some Compaq
computers will display the message "F12 Network Service Boot" on the
Compaq banner screen.

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.
