Gigabyte GA-B150M-D3H DDR3 BIOS firmware for board revision 1.0, packed in a 6.51 MB RAR archive. The DDR3 designation separates this variant from the DDR4 version of the B150M-D3H, so make sure the board in hand carries DDR3 slots. A full image of this size is normally flashed to the SPI chip with a CH341A or similar programmer when the board fails to post or the BIOS is corrupted. Check the chip capacity matches the image, confirm the PCB revision, and dump the original chip first since it holds the board MAC and serial data.
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.
