The eeupdate64eefi tool (often referred to within the Intel Ethernet NVM Update Tool suite) is a specialized command-line utility designed for advanced IT administrators and firmware engineers. Its primary purpose is to flash, update, or recover the —commonly known as EEPROM—on Intel Ethernet Network Adapters.
| Tool | Environment | Scope | |--------------------------|-------------------|------------------------------------------------------------| | eeupdate64eefi | UEFI shell (x64) | Full NVM management for Intel Ethernet (desktop/server). | | eeupdatew64.exe | Windows (64‑bit) | Similar functions, but requires Windows driver access. | | bootutil64e.efi | UEFI shell | Boot option management only (PXE, iSCSI, FCoE), not NVM. | | nvmupdate64e.efi | UEFI shell | Intel’s newer unified updater (supports more recent NICs). | | ethtool (Linux) | Linux userspace | Read EEPROM, register dump – no firmware write. |
Due to its ability to permanently alter hardware identity and function, Intel classifies eeupdate64eefi as a sensitive tool. It is typically distributed via the Intel Resource & Design Center
