Clone MAC Address

[user1]

I,m looking to find a solution to flash firmware for a network Realtek rlt8139 card, because I need to CLONE MAC Address. All software solution failed.... Just an idea of mine: It is possible to compile a virtual network adapter driver Virtual Box and change MAC to desired one?

Haven't tried myself but might get you started:
1) http://flashrom.org/
2) BootROM Flash utility from http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=6&PFid=6&Level=5&Conn=4&DownTypeID=3&GetDown=false

hi all
i think the mac address is in eeprom so u can just clone the eeprom of your ethernet board used as security devices if the ethernet board are from the same manufactur or just change mac address if diff manufac

Some software checks if MAC spoof is used.... So I have changed MAC and after that I just deleted checked registry entry... works until restart.
