Even experts encounter issues. Here’s how to solve them:
| Error Message | Meaning | Solution |
|---------------|---------|----------|
| "Top block write protected" | OEM lock enabled | Use /forcewrite or /oemunlock (if available) |
| "File size does not match top block sector" | Firmware image wrong | Extract only the top sector using a hex editor (offset + size from datasheet) |
| "EEPROM timeout" | Signal interference or power issue | Unplug server, wait 30 sec, try again. Remove other PCIe cards. |
| "Checksum error after verify" | Bad flash chip or voltage | Do not reboot. Immediately run /top again with /forcewrite. |
Do not run this command casually. Follow this checklist precisely:
The command eeupdate64eefi /top (or simply running the tool without specific flags) is used to display a top-level summary of all Intel Network Interface Cards (NICs) present in a system via the UEFI Shell. Quick Start: Running the "Top" View
Boot to UEFI Shell: Ensure your Intel Ethernet Flash Firmware Utility (eeupdate64eefi.efi) is on a bootable USB drive formatted to FAT32.
Locate the Tool: Switch to your USB drive (usually fs0: or fs1:) and navigate to the directory containing the utility. Execute: Run the following command to see the adapter list: eeupdate64eefi /top Use code with caution. Copied to clipboard Understanding the Output Columns
When you run this command, the utility generates a table with the following key information for every detected Intel NIC: eeupdate64eefi top
NIC: The index number assigned to the adapter (e.g., 1, 2, 3). You use this number for targeted commands (e.g., /nic=1).
Bus/Dev/Fun: The PCI address of the device (Bus, Device, and Function).
Vendor-Device: The PCI ID (e.g., 8086-1533). 8086 is the standard Intel Vendor ID.
Subsystem ID: Specific manufacturer branding or model information.
MAC Address: The current physical address programmed into the EEPROM/NVM.
Device Name: A human-readable name (e.g., "Intel(R) I210 Gigabit Network Connection"). Common Follow-up Commands Even experts encounter issues
Once you have identified your NIC index from the /top view, you can perform specific maintenance tasks: Command Syntax Check Inventory 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
Correct Tool Version: Ensure you are using the version that matches your hardware (e.g., eeupdate64e.exe for DOS/Windows vs eeupdate64eefi.efi for UEFI).
Backup First: Always run /dump before attempting to flash or change a MAC address.
Single Adapter Focus: If you have multiple identical NICs, use the /nic=[index] flag to avoid updating the wrong port.
EEUPDATE64E.EFI is a powerful Intel command-line utility used to update or modify the non-volatile memory (NVM) or EEPROM of Intel Ethernet adapters in a UEFI environment. It is frequently used for advanced tasks like changing MAC addresses, updating firmware, or fixing "unclaimed" adapter issues. Intel Community 1. Getting Started To use this tool, you generally need to boot into a UEFI Shell Preparation : Format a USB drive to FAT32. Place the eeupdate64e.efi file (and any required firmware files) on the root of the drive.
: Disable Secure Boot in your BIOS settings. Boot from the USB drive. If your system doesn't automatically boot to the shell, you may need to rename the shell executable to bootx64.efi /EFI/boot/ folder on the USB. Fedora Discussion 2. Common Commands | | "Checksum error after verify" | Bad
Once inside the UEFI shell, navigate to your USB drive (usually ) and use the following core commands: List Adapters eeupdate64e.efi /ALL /DUMP
This lists all detected Intel NICs and their current configurations. Update MAC Address eeupdate64e.efi /NIC=X /MAC=XXXXXXXXXXXX Replaces the MAC address of the specified NIC (where is the adapter number found in the list command). Update Firmware/EEPROM eeupdate64e.efi /NIC=X /DATA [filename.bin] Writes a specific binary file to the adapter's EEPROM. Check Inventory eeupdate64e.efi /NIC=X /INVENTORY
Displays detailed hardware information, including the PBA and ETrackID. Level1Techs Forums 3. Essential Tips for Success Verify Files : Before flashing, run a
of your working card to keep a backup of your original firmware and MAC address. Tool Source
: Intel often restricts direct public downloads of this tool for specific enterprise/embedded needs. You may need to look for it within official Intel firmware update packages for your specific NIC series (e.g., the 700 Series NVM Update Package Error Prevention
: If the utility doesn't see your card, double-check that you are using the
(64-bit EFI) version and that the adapter is supported by your current EFI LAN driver. Level1Techs Forums exact syntax
