I had one with a bad battery that I had to reset the MAC address on by hand if I unplugged it for too long. They DID implement a check to make sure the first few bits were correct for the product, though. I couldn't pick completely random MACs (though C0FFEE fit nicely at the end). Given a working nvram, this change was "permanent", and the only tools needed came with the system. Erik -- Ask not what your computer can do for you.
