Flash Mac to Nic? I wouldn't recommend ever flashing a nic with a new Mac address.
If you look at step 5 in the guide on the first page of this thread, it tells you what you should do with the Mac address.
Oke thanks. So i have to add 2 MACs? and i can generate these macs and serial using the calculations online, but i have to flash them to the cards as well am i right?
