This tool can change MAC address, returned by GenMac NdisReadNetworkAddress function to Windows drivers.
What does it mean?
* you can change MAC address of your card, but only if you have ONE
network card in system and only if windows network driver correctly
handle this value (it must).
* this tool PATCH your ?:\IBMCOM\MACS\genm32w.os2
* now I see normal MAC instead of 00-00-00-00-00-00 on my "Intel 82566DC Gigabit" network card
