    What's the range(offset) where will be checksum calculated for X722 EEPROM?

    mingfeng2116

      We would like to burn MAC address of x722 (8086-37D0    Intel(R) Ethernet Connection X722) via ICT (In Circuit Test) instead of using ''eeupdate" tool.

         

      "%eeupdate /nic=x /dump" got a EEPROM FILE, 128KB, (attached)

      1. Looks like checksum was stored at offset "0x3F" (0x3F in WORD addr, 0x7E-0X7F in 8bit addr), is this correct?

      2. Would like to know how to calculate its checksum and what the calculation range?

      3. Any chance to get an EEPROM MAP of x722?

      Thanks
