Working BIOS image for the Gigabyte H410 S2 V3 desktop motherboard, PCB revision 1.2, sized 16 MB and marked OK. Desktop boards of this kind use a 128 Mbit SPI flash, and a clean dump lets a technician revive a board stuck in a boot loop or with corrupted firmware by programming the chip directly with a CH341A or similar tool. Gigabyte revisions can differ in hardware, so match the revision printed near the PCI slots, back up the existing chip, and confirm the image is the same size as the flash.
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 →
