Most motherboards today has a built in NIC and support Wake on LAN functionality.
			*NOTE: Most PCs today have the above specifications built-in. You may check if your have a PC that supported WOL by checking in the Power Management option in BIOS.

	=='''Example Lab'''==		=='''My Example Lab'''==
	In this lab, I will walk you through the steps of enabling WOL, installing utility software, and testing it on a local area network. I used a PC and a laptop which both connected to a ~~cisco~~ switch. ~~the~~ switch connected to a router. I ~~enable WOL and Remote Desktop Connection on the~~ PC, and ~~used the laptop to turn on the PC~~, and ~~then connected to~~ the ~~PC using Remote Desktop Connection~~.		In this lab, I will walk you through the steps of enabling WOL, installing utility software, and testing it on a local area network (LAN). I used a PC and a laptop which both connected to a switch. The switch connected to a router that has connection to the internet. The PC I used in this lab is a custom built PC, and it has Windows XP Operating System installed. The installed motherboard is ASUS Rampage II Formula witch has quad ports NIC built-in, and the power supply is BFGR650PSU manufactured by BFG Tech.

	~~===Hard ware of the PC===~~		The performed this lab as follow:
	~~A PC which supports WOL is required. In~~ this lab~~, this PC will be called "target PC". Hardware requirement for this PC includes~~:		#Enable WOL on the PC.
	# ~~An ATX motherboard with an onboard, 3-pin "~~WOL~~" connector~~.		#Install a WOL utility on the laptop.
	# ~~A network card that can support~~ WOL ~~with its cable to~~ the ~~motherboard properly installed~~.		#Use the utility to trigger power on of the PC.
	# In the ~~BIOS Power Management, you must enable~~ the ~~LAN Wakeup option~~.		#Test to see if the PC has power on or not using ping command.
	# ~~An ATX~~ power ~~supply that meets ATX 2.01 specifications~~.		#Connect to the PC using Remote Desktop Connection software.
	~~Most PCs today have~~ the ~~above specifications motherboards that have a built in NIC and support Wake on LAN functionality~~.

	===Enabling WOL===		===Enabling WOL===
			In order for WOL to work, WOL feature must be enable in BIOS and Operating System. The process of enabling WOL may be different for each motherboard, so you may need to do some research on your motherboard.
			*On the ASUS Rampage II Formula, there are two options that must be enable in BIOS and also two option in Windows XP. WOL feature is enabled on my PC by following the steps bellow.
			#Enable "LAN Boot ROM". Power on the PC and press Delete key to enter the BIOS setting, and then select "Advanced>LAN Boot ROM>Enabled".
			#Enable "Power On By PCIE Devices". Select "Power>APM Configuration>Power On By PCIE Devices>Enabled".
			#Go to "Exit and save changes" to save the setting. Then it will boot into Windows Operating System normally.
			#On Windows XP, go to "Start>Control Panel>Network Connection". Right clicking on "Local Area Connection>Properties". Click on "Configure" button, and click on "Advanced" tab. Scroll down until you see "Wake From Shutdown" and "Wake Up Capabilities".
			#Select "Wake From Shutdown" and change the value from Off to "On".
			#Select "Wake Up Capabilities" and change the value to "Magic Packet".
			#Click "OK" to save the changes.

	===~~Installing~~ WOL Utility===		Now the PC is ready for WOL, but you need to make notes of the Mac and IP address of the PC. I used ipconfig /all command to verified made notes of the MAC address and IP address of my PC, and then shut it down.

			===Downloading WOL Utility===
			There are many tools that you can use to trigger power on of a PC with WOL feature enabled. I used "MC-WOL.EXE" utility. This utility is a DOS command line utility that sends a "Magic Packet" to trigger power on of remote computer. MC-WOL.EXE can be download at http://www.matcode.com/wol.htm.

			I have Windows 7 Operating System installed on my laptop. I downloaded MC-WOL.EXE and saved into C:\Users\LUE directory.

	===Testing===		===Testing===
			Now I tested WOL to watch my PC turn on using the following command. The XX:XX... is the mac address of the PC witch has WOL enabled.
			mac-wol xx:xx:xx:xx:xx:xx

			If the PC with WOL enabled is not physically visible, you can use the ping command with -t string to test and see if the target PC is powered on or not. After a few minutes, the ping should be successful if you have setup everything correctly. And if the target PC has Remote Desktop Connection enabled, you can remotely connect to it.
