BIOS package for the H310M S2H motherboard, labeled for revision 1.x, in a 6.67 MB ZIP. The H310M S2H naming and rev. 1.x style match Gigabyte desktop board conventions, but the file name does not state the brand, so confirm the model on the board. A BIOS image can be flashed through the vendor update utility or written directly to the SPI chip with a programmer when the board will not post. Back up the current chip and check the revision printed near the slots.
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.
