Two identical MBs' w/ the same MAC addresses

I have two Foxconn N570SM2AA MB's;
http://www.foxconnchannel.com/en-us/...D=en-gb0000205

They have two built in ethernet controllers. Controller One on each board has the SAME identical MAC address as does Controller Two on each board. I was under the understanding that every ethernet device had a different address even the same model.

I was having a problem with these two PCs' talking to one another. My third box is a Laptop and there was no issue here. All are using XP Pro through a Westell VersaLink 327W DSL modem/router. It was also causing issues with the router as both boxes had the same MAC address.
Input??

There is often a setting in the BIOS to change the MAC address of the system, or worst case scenario search for a MAC address spoofing program and just run that on one of the boxes to change your MAC address from inside windows, if using Linux get a program called macchanger from the ubuntu/debian repositories.

It can happen, they're supposed to make it so that it doesn't but sometimes it'll get messed up.
