eeupdate64e.efi
The utility is a specialized, 64-bit UEFI-based command-line tool developed by Intel for managing and updating the EEPROM and Non-Volatile Memory (NVM) on supported Intel Ethernet network adapters. It is primarily used by system administrators and developers to modify low-level hardware settings, such as MAC addresses, or to flash firmware in pre-boot environments like the UEFI Shell . Key Capabilities of eeupdate64e.efi
- Generic version – supports most Intel 1GbE, 10GbE, 25GbE, 40GbE controllers.
- OEM versions – locked to specific brands (Dell, HP, Lenovo) with custom NVM layouts.
- VPD-enabled versions – include extra commands for Vital Product Data.
As Intel transitions to newer Ethernet controllers (E810, E830 series) with more secure update mechanisms (signed capsules, hardware root of trust), the direct EEPROM manipulation approach is being phased out. Intel now recommends: eeupdate64e.efi
- Ensure the card is properly seated in the PCIe slot.
- Try the
/allswitch again. - Some OEM cards (like Dell/HP branded Intel cards) have specific Subsystem Vendor IDs that the generic tool might ignore. You may need a patched version of
eeupdate.
The utility allows for low-level interaction with Intel network hardware, supporting various tasks: MAC Address Configuration eeupdate64e
Primarily used in data center and enterprise environments, this tool allows administrators to interact directly with Network Interface Cards (NICs) at the hardware level before an operating system is even loaded. It is often used for: Generic version – supports most Intel 1GbE, 10GbE,
eeupdate– Stands for "Ethernet EEPROM Update." Historically, network cards stored configuration data in an EEPROM (Electrically Erasable Programmable Read-Only Memory). The tool is used to read from and write to that storage.64– Indicates the tool is compiled for 64-bit architectures.e– Denotes the EFI (Extensible Firmware Interface) version, specifically for UEFI (Unified Extensible Firmware Interface) environments..efi– The standard file extension for UEFI applications.
eeupdate64e.efi is a powerful but dangerous tool—a scalpel, not a hammer. When used correctly, it gives you complete control over Intel Ethernet adapters at the firmware level. When misused, it can permanently destroy a $500 network card. Always back up, verify your environment, and respect the legal boundaries of MAC address modification.
The tool is executed from a UEFI shell, typically from a bootable USB drive: eeupdate64e.efi : Displays all available NICs and their IDs. eeupdate64e.efi /ALL /MAC_DUMP : Lists all MAC addresses for detected devices. eeupdate64e.efi /NIC=1 /MAC=XXXXXXXXXXXX : Updates the MAC address for a specific NIC. eeupdate64e.efi /NIC=1 /DATA .eep : Flashes a specific data file to the selected NIC.
