ZIP archive of 4.05 MB containing a BIOS for the ASUS P8H61-M LX3 R2.0 motherboard, version 1107 per the name. The H61 chipset places it in the Intel LGA1155 generation. The compressed package likely holds the official update file, which can be flashed through the ASUS EZ Flash utility when the board still boots. For a board with a corrupted BIOS, the image may need preparing for a programmer. Confirm the board revision matches R2.0, since images for other revisions may not work.
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 @oficinacomputadores. Enginerys does not host this file.
