BIOS for the MSI B85M Gaming motherboard, board code MS-7823, stored in a 7.47 MB RAR archive. No version number or PCB revision is given in the name, so compare it with the board you are repairing. The MS-7823 platform covers several B85M models, and flashing the wrong variant can leave a board without video or POST. Use an SPI programmer to read and keep the original chip contents, then write this image only if its size matches the flash chip capacity and the model is confirmed.
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.
