• Physical Access (Recommended) – If the flash fails, you may need a hardware programmer. Do not run this over remote iLO/iDRAC unless you have console redundancy.
• Intel Network Adapter – Verify your NIC is genuine Intel (e.g., i210, i350, X710, XL710, E810). Broadcom or Mellanox cards will be ignored.
• UEFI Shell Access – Boot into a UEFI shell (not Linux/Windows). You can create a bootable USB with EFI/BOOT/bootx64.efi.
