It runs exclusively within a UEFI Shell environment , not inside Windows or Linux. Purpose: It allows technicians to:
If your target motherboard lacks a built-in EFI shell, download a standard Shell.efi binary, rename it to bootx64.efi , and place it in the /EFI/BOOT/ directory of your USB drive.
Before making any changes, . This allows you to revert to a known working state if something goes wrong.
command before making any changes. This is your only "undo" button if a firmware flash goes sideways. OEM Restrictions: eeupdate64eefi top
If you are actually trying to run the command eeupdate64eefi and want to see the top of the list (or the beginning of the output), you usually cannot use the word "top" as an argument. In the EFI shell, you typically use: eeupdate64eefi /all (to list adapters) Then select the specific index, e.g.: eeupdate64eefi /nic=1 /file=firmware.bin
Updates the MAC address for the selected NIC (e.g., /NIC=1 /MAC=001122334455 ). /D [filename] Dumps the EEPROM/NVM content to a file for backup. /DATA [filename] Flashes a specific data file or image to the controller. /EEPROMVER Displays the current version of the EEPROM firmware. How to Use EEUPDATE64EEFI
Here are the most common and essential command-line parameters for eeupdate64eefi . 1. Listing All Intel NICs It runs exclusively within a UEFI Shell environment
eeupdate64e.efi (EEPROM Update Utility for EFI 64-bit) is a command-line tool developed by Intel. It is used to manipulate the NVRAM/EEPROM on Intel Ethernet controllers.
This generates an output file saving the original factory code string. Step B: Modifying the Hardware MAC Address
Example:
When deploying customized operational parameters or recovering firmware, flash an official Intel .eep configuration payload directly to the chip: eeupdate64e.efi /NIC=1 /DATA=I350_Custom_Config.eep Use code with caution. 4. Updating or Repairing Checksums
Enumerating all installed Intel network controllers alongside their respective Bus, Device, and Function (BDF) mappings. Prerequisites: Setting Up a UEFI Boot Environment
