How do I update the BIOS using ASUS EZ Flash 3?

Insert a FAT 32/16 formatted USB flash drive containing the latest BIOS file into a USB port, then enter Advanced Mode in BIOS and navigate to the Tool menu to select ASUS EZ Flash 3 Utility. Use the arrow keys to locate the USB drive and BIOS file, then press Enter to begin the update. Do NOT shut down or reset the system during the update process, as this can cause boot failure.
