BIOS dump labelled working for the Gigabyte GA-B150M-D2VX-SI, board revision 1.0, provided in a RAR archive of about 16.0 MB. The archive may contain more than one image, so inspect its contents and select the file that matches your flash chip size. Recovery normally means desoldering or clipping onto the SPI chip and writing the image with an external programmer. Make a backup of the existing contents first and confirm the revision on the PCB is 1.0 before writing.
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.
