How to find Intel X520-DA2 10 Gigabit Ethernet NIC adapters in UEFI - IBM Servers


RETAIN tip: H207307


The Intel X520 10 Gigabit (Gb) Ethernet adapter's Option ROM is disabled by default and therefore the adapter is not seen in UEFI and not available as a Preboot eXecution Environment (PXE) resource.

Affected Configurations

The system is configured with one or more of the following IBM options:

  • Intel X520 10 Gigabit Dual-Port Ethernet SFP+ Embedded Adapter for IBM System x, option 49Y7980, any replacement part number
  • Intel X520-DA2 10 Gigabit Dual-Port Ethernet SFP+ Adapter for IBM System x, option 49Y7960, any replacement part number

This tip is not system specific.

This tip is not software specific.

The system has the symptom described above.


The following steps will enable the option ROMs on the Intel adapters:

  1. Create the ISO for the Intel software to a CD.
  2. Open the Intel Software.
  3. Open the 'Start_UEFI_ISO' folder.
  4. Copy 'efi_boot_update.iso' to a Hard Disk Drive (HDD).
  5. Burn 'efi_boot_update.iso' to a CD.
  6. Insert the 'efi_boot_update' CD into the server with the Intel NICs.
  7. Start to the 'efi_boot_update' CD.
  8. Wait until the 'Shell>' prompt is displayed.
  9. At the 'Shell>' prompt, enter this command:

      Shell>bootutil64e.efi -all -FE
  10. Press Enter.
  11. After the procedure finishes, type 'exit.'
  12. Restart the server.
  13. Press F1 to enter UEFI.
  14. In UEFI, select System Settings -> Network, to see the adapters.

If the UEFI 'efi_boot_update' CD does not start, complete the following steps, which should allow the CD to start:

  1. Restore UEFI defaults.
  2. Load the CD and follow the instructions that Product Engineering (PE) provided previously.
