BIOS file for a board identified as SG-80DC, compressed into a 349 KB ZIP archive. The DC suffix marks a variant distinct from the plain SG-80, so the exact model code on the PCB must match before flashing. Nothing else about chipset or version appears in the name. Extract the image and verify its size against the BIOS chip, then save the original contents with a programmer or flashing tool. Using a file meant for a sibling variant can leave the board unable to start.
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.
