How to update the Bios of the computer motherboard? Can I use a USB flash drive?

Many motherboards introduced in recent years can use USB flash drives to upgrade and back up the motherboard BIOS. For example, P43-ES3G motherboard produced in Gigabyte in 2009 supports upgrading BIOS from USB flash drive and mobile hard disk, but requires that USB flash drive and mobile hard disk must adopt the file format of FAT/FAT 16/FAT32. Basically, the new BIOS file is stored in a USB flash drive, and the BIOS file is read by pressing the shortcut key or entering the BIOS to call the integrated upgrade and refresh program for related operations. The operation of upgrading BIOS for different brands of motherboards is different. Please refer to the motherboard user manual for details. In addition, motherboard manufacturers such as Gigabyte have also introduced their online BIOS update software under Windows system, which is used for networking BIOS upgrade operation. Note: There are potential risks in upgrading the BIOS. Please pay attention to avoid system damage caused by improper operation!
