How to do Wake on LAN

I am amanging some pcs which don't have Wake on lan on BIOS. I have checked their BIOS but there is no such option under POwer management. Even though network card has wake on lan option but there is no option in BIOS. I need to wake them up at night to push updates and other maintenance. I am wondering what other options I have if they can't be wake up using BIOS option.What other option I have to wake them up ? I am using SCCM to manage them.

I think updating BIOS would be lot of work..10 /12 pcs are doing same thing and I am not sure if I have so much time to update BIOS...I would appreciate if you could advise some quick steps.
P1339..I did update drivers on some of the pcs and I went to NIC card options and under Advanced and Power Managment Tab , i did select those options. I am aware of those steps.
Sarus_SKS...whre do I see NIC card only support? I will check if BIOS has those option under Boot tab.

To find out the exact model of the system board do the following.

Download Windows System Information Utility (portable version):
When you run the utility, on the left side select Hardware - Motherboard. When we know the model of the system board we can find a BIOS update. We really only need to update one computer to see if this works.

Here is a link to download the bios update:

You will need to create a bios update disk/cd. Here are the instructions:

There are two files to the bios update. Make sure you add both to the bios update disk.
Let know how it goes.
