Experienced users strongly recommend this step. As one forum post notes: “Boot to UEFI … dump file will be MAC.EEP … Backup this file. Rollback is simple.”
Modifies device configuration data (settings) in the EEPROM.
Example: Dumping NIC 1
Once you are on the correct filesystem (for example, fs0:\> ), you can list the contents with ls to confirm that eeupdate64e.efi is present. eeupdate64eefi work

Obtain the eeupdate64e.efi binary and the correct .bin or .eep firmware image for your network adapter. Boot to EFI Shell: Boot the server/PC into the UEFI shell.
Network administrators, system integrators, and homelab enthusiasts rely on this tool to change hardware MAC addresses, dump EEPROM contents, flash updated network firmware, and configure advanced adapter settings. Operating directly from the UEFI shell bypasses any driver restrictions or safety locks imposed by standard operating systems like Windows or Linux. Prerequisites: Setting up the UEFI Shell Experienced users strongly recommend this step
Overall, eeupdate64.efi is a useful tool for updating the firmware of Intel-based systems. When used properly, it can help improve system stability, security, and performance.
| Command | Purpose | | :--- | :--- | | eeupdate64e.efi | Displays a list of all Intel network adapters found in the system, along with their bus/device/function addresses, device IDs, and branding strings. | | eeupdate64e.efi /all /adapterinfo | Shows detailed adapter information for every NIC. | | eeupdate64e.efi /nic=X /adapterinfo | Shows detailed information for a specific adapter, where X is the NIC index number displayed in the inventory list. | | eeupdate64e.efi /all /eepromver | Reports the current EEPROM image version for every adapter. After a firmware update, this is the first command to run to confirm success. | | eeupdate64e.efi /nic=X /eepromver | Checks the EEPROM version for a single adapter. |
Before attempting to run eeupdate64eefi , ensure the following: Example: Dumping NIC 1 Once you are on
Operating within an EFI/UEFI environment (pre-OS), this tool allows for low-level configuration, including updating NIC firmware, changing device IDs, and modifying MAC addresses. What is eeupdate64eefi and Why Use It?
Example script ( update_all.nsh ):
If you are dealing with a "No Intel Adapters Present" scenario or a failed flash, eeupdate64eefi is generally the best tool for recovery. If you are currently facing a specific error, let me know: What is the model of your Intel Network Adapter? I can provide the specific command for your scenario.
