where is the pci ethernet card's mac address?

where is the pci ethernet card's mac address?

[caokai]

Hi
    In my opinion,a pci ethernet card(intel eepro100)'s mac address
should store somewhere in the PCI cards.
    But in my EST8245 board,it seems the mac address is provided by the
bsp(e.g EST VisionWare)?
    So,if I run the linux without the VisonWare.It have a mac address
00:00:00:00:00:00:00.
     I am confusion now.Any advice?
regards
caokai

Normally in a small eeprom, yes.

Possible, but unlikely.

Which, for recent versions of the kernel, will get you exactly
nowhere.  (In my experience the kernel will refuse to respond to ARP
requests for its address(es) if the requested IP address has an
associated all-zeros MAC address.

Use the source, Luke.
