| Requirement | Why It Matters | | :--- | :--- | | A UPS battery backup | A power outage during the 2-3 minute flash process destroys the motherboard. | | A FAT32-formatted USB flash drive (4GB to 16GB) | BIOS flashing tools cannot read NTFS or exFAT. | | The correct BIOS ROM file | Renamed to something simple like BIOS.ROM (check your board's manual for required naming). | | A fully stable system | Run MemTest86 or Windows Memory Diagnostic first. Faulty RAM will corrupt the flash. | | Reset BIOS to defaults | Enter BIOS (Del/F2 on boot), press F9 for Optimized Defaults, save and exit. |

Most ECS H61 boards have a built-in flash utility in the BIOS.
