It is used to apply firmware updates or flash specific configuration images (like files) to Intel controllers Hardware Inventory:

If your motherboard shows a generic 00:00:00:00:00:00 or 15:21 identity failure after a botched BIOS update, apply a new address directly: Shell> eeupdate64e.efi /NIC=1 /MAC=AABBCCDDEEFF Use code with caution.

The Intel Atom C2000 documentation explicitly warns that performing EEPROM updates on X540-AT2 ports will cause them to stop functioning.

The eeupdate64e.efi utility is an engineering deployment tool. It is not distributed as a standard, public consumer download.

The is the primary command-line tool used by network administrators, hardware developers, and system integrators to flash, modify, and configure Intel Network Interface Card (NIC) EEPROM and Non-Volatile Memory (NVM) images directly from a Unified Extensible Firmware Interface (UEFI) Shell. Mastering the utility’s commands—specifically how to display its top flags, help outputs, and diagnostic parameters—is vital for modifying MAC addresses, upgrading firmware, and resolving hardware configuration issues on modern servers.

Using eeupdate64e.efi , the recovery workflow is:
