I, too, was going to suggest that Pete. However, why would one care what the hard adapter address is? That's why I always assign one when I create a line description. This way my saves and restores don't confuse network equipment that might have linked the old hard mac address. Been doing this since, well, when serial numbers were numeric and I embedded that into my mac address. Then I started doing stuff like division number, etc. Then it got really run converting TR mac addresses to Ethernet.
