Pull Mac address from disconnected mobo?

[EnterTheDragon]

I recently built a new computer for my brother. After installing all the old disks into the new computer I realized that I forgot to pull the MAC address from his onboard-lan. Is there anyway I can pull up the MAC address without having to reconnect all the drives? It's a Dell, can I use the service number online to retrieve it? Thanks

I don't think you can do it without powering it up...

Since the Mac address is supposed to be unique for each piece of networking hardware, you'll either have to get it off the board itself (it may have it printed somewhere), or you have to reconnect it

I'd look at the old board as well...the MAC is usually printed on a little sticker on the lan jack or in the lan chip area.

BTW: Why do you need the MAC anyway? I can think of very few reasons you even need the old address (other than MAC filtering on routers or ISP's)
