RAR archive of 2.57 MB holding BIOS firmware for a board named H61S1, with mp1.0 in the name, likely referring to board revision or mass-production version 1.0. H61 points to the Intel H61 chipset used on many low-cost LGA1155 desktops. Use the image to reprogram the SPI flash chip when the board shows no video or loops on power-up. Extract and inspect the file first, confirm the board marking on the PCB, dump the original chip as a backup, and ensure the image matches the chip capacity 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 @Laptopdesktopbios. Enginerys does not host this file.
