Main BIOS for the Gigabyte GA-H61M-DS2 desktop board, revision 2.0, marked OK, with a size of 4.00 MB and no extension in the name. The image suits a 4MB SPI flash chip. Gigabyte revisions of this model can differ in hardware, so check that the PCB reads rev 2.0. Program the chip with an external programmer to recover a board that fails to post after a bad flash, backing up the original contents first and verifying after 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 @bios_laptopomi. Enginerys does not host this file.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
