BIOS image for the ASUS B85M-G desktop motherboard, an Intel B85 chipset board, provided as a 4.49 MB RAR archive with no version stated in the name. It can be applied through ASUS EZ Flash or BIOS Flashback where supported, or written to the SPI chip with an external programmer to recover a board that no longer posts. Check whether the file is a raw dump or an update capsule, save the original chip contents first, and make sure the image size matches the flash chip.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
