We noticed that the MAC address of the EG20T IOH is obtained from an EEPROM, which is connected to the Serial ROM interface of the Intel EG20T IOH. We'd like to know how we can write a MAC address into this EEPROM? Preferably, we want to perform such a MAC address write on the UEFI layer (for example, from the UEFI Shell interface).
Does anybody know how to accomplish this?
There is a tool available in this link http://sourceforge.net/projects/generalembedded/files/ General Embedded - Browse Files at SourceForge.net Intel PCH Hub MAC Programming Utility
Please go through the ReadMe in this DIR phub_util_mac
This tool is used to write mac address in the OS level.
