BIOS archive for the ASUS PRIME B250M-K desktop motherboard, with 1205 apparently being the firmware version. At almost 7 MB it likely contains the full flash image or the update file. It can be applied with EZ Flash, or written to the SPI chip directly with a programmer when the board will not post. Save a backup of the existing chip and check that the image size suits the flash chip on your board before writing it.
