: Used by technicians to restore a MAC address if it was accidentally wiped during a CMOS clear or motherboard repair.
Need help finding the exact firmware for your Intel adapter? Refer to Intel’s official NVM Update Matrix or contact your server OEM’s support center with the PCI Device ID (e.g., 8086:1572).
If you are correcting an invalid default signature on an uninitialized network card, assign a specific physical address sequence:
: Selects a targeted adapter index (numbered 1 through 32) to isolate changes to one specific physical port. eeupdate64eefi top
If you have an onboard Intel NIC (built into an ASUS or Dell motherboard), these generic Intel tools might not always work. OEMs often use customized firmware that requires specific manufacturer tools. The i350 "Hang":
Once you have identified your NIC index from the /top view, you can perform specific maintenance tasks: Command Syntax eeupdate64eefi /nic=[index] /inv Update MAC Address eeupdate64eefi /nic=[index] /mac=[new_mac] Flash Firmware eeupdate64eefi /nic=[index] /d [filename.bin] Dump EEPROM eeupdate64eefi /nic=[index] /dump Safety Best Practices
While there are many commands, these are the most common scenarios for using eeupdate64e.efi : 1. Restoring or Changing MAC Addresses : Used by technicians to restore a MAC
While community forums and blog sites (GitCode, CSDN, cnblogs, etc.) offer eeupdate64e.zip or the .efi file directly, : you cannot verify the tool’s integrity, it may be out of date, and you may inadvertently use a version incompatible with your adapter. Use such sources with caution.
Before making changes, you should identify the network adapter(s) you want to modify. This command also lets you verify the current firmware version and MAC address.
Example:
In the world of network engineering and system deployment, having direct control over hardware firmware is essential. is a powerful command-line utility designed to run in a UEFI (Unified Extensible Firmware Interface) Shell environment. It allows users to modify the EEPROM, update firmware, and manage the Vital Product Data (VPD) of Intel Ethernet controllers. What is EEUPDATE64EEFI?
for a certain task, like updating a MAC address or flashing a new image? Intel® Ethernet NVM Update Tool - 31.1 - ID:705831
This would help an engineer quickly identify which adapter’s EEPROM is failing or which has a mismatch. If you are correcting an invalid default signature
