Small RAR archive of firmware labelled ELBRUS R1.4 BIOS, 575 KB in size. The name gives only the label Elbrus and what looks like revision R1.4, with no brand, board number or chip details, so identifying the exact target hardware is up to the technician. Before programming, compare the extracted image size to the capacity of the flash chip on the board, read and save the original contents with an SPI programmer, and confirm the board revision marking matches R1.4.
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.
