EEUPDATE64EFI is a command-line utility developed by Intel specifically for its network interface controllers (NICs). It is designed to run within an EFI (Extensible Firmware Interface) shell
Here are the most common ways to use the tool in the EFI environment: eeupdate64e.efi /all
This saves a raw copy of the EEPROM configuration from the first adapter into a file (usually ending in .EEP ). This step is essential before making any structural changes. Programming a New MAC Address eeupdate64e.efi /NIC=1 /MAC=001122334455 Use code with caution.

Intel Ethernet adapters are the backbone of countless server rooms, embedded systems, and high‑performance workstations. At some point, many systems administrators, firmware engineers, and hardware enthusiasts need to update a network card’s firmware, restore a corrupted EEPROM, or change a MAC address without relying on an operating system. For these low‑level tasks, one utility consistently rises to the top: .
While EEUpdate64Eefi is designed to work seamlessly, issues may arise during the update process. Common problems and their solutions:
Users sometimes see a "No config file entry" error when running EEUPDATE64e.efi , particularly with high-performance NICs like the X710.
: The tool can force a recalculation of EEPROM checksums and CRCs using /CALCCHKSUM to ensure data integrity after manual modifications. EEUPDATE64EFI is a command-line utility developed by Intel
Because modern architectures dictate a native UEFI framework, running eeupdate64e.efi requires setting up a bootable Pre-Boot environment. How to download eeupdate64e.efi tool ? - Intel Community
Example: Dumping NIC 1
: Use the fs0: (or appropriate drive label) command to switch to the directory containing the .efi file.
After the command completes, rebooting the system will cause the adapter to present the new MAC address to the network. Programming a New MAC Address eeupdate64e
