Hardcoded/Embeded serial numbers on PCs

What I am trying to do is, get a PC’s serial number through Remoteware. We are using Dell’s. I know it can be fashed in the Bois as an asset tag #, but that has not been done. Is there another way to find the serial numbers remotely or a utility that is able to do that. I’m thankful for any help.
