  1. A USB Flash Drive: Formatted to FAT32 (not exFAT or NTFS). 8GB or 16GB is ideal.
  2. The Correct BIOS File: Go to your motherboard’s support page on the ASUS website. Double check your exact model number (e.g., ROG STRIX B550-F).
  3. A UPS (Uninterruptible Power Supply): Crucial. If the power goes out during the 2-minute flash, your motherboard is a paperweight. If you don't have a UPS, do this on a laptop battery or during stable weather.
  4. Patience: Do not touch the reset button or force shut down.

Capacity: A drive of at least 1GB is recommended, but it must be under 32GB for some systems to recognize it correctly. Mastering the ASUS EZ Flash 3 Utility v03
