Configure MAC address on boot

[BK4u]

Hey I'm remastering a copy of Knoppix 3.9 and I want to set a specific MAC address when the system starts up, how would I go about configuring that?

Thanks that looks like it should work. One more question though, is it possible to specify a specific MAC and still have the IP assigned by DCHP? Because when I change the MAC I am not able to ping anything, it looks like the default gateway is 0.0.0.0
