Re: Re: forcedeth generates Invalid MAC address message


The first byte of your MAC address is 1d, i.e. 00011101. On http://en.wikipedia.org/wiki/Mac_address (the figure): if the last bit of the 1st byte is 1, then it is a multicast address, NOT a unicast one. As such, it cannot be the "main" address of a NIC. Maybe the address reading has a problem? On some laptops, the MAC address is printed on the back side of the laptop. Can you look at it?

You can also use http://standards.ieee.org/regauth/oui/index.shtml to find out the enterprise which has built a NIC.
