May I inquire as to the reason for your current need to update the BIOS? For instance, have there been any hardware changes? You can perform a BIOS update by following the guide provided in the [Motherboard/Desktop] ASUS EZ Flash 3 - Introduction. Please note that the USB driver you use for this update requires a single sector in FAT 16/32 format, and it is recommended to have a capacity of 1GB or more.
