BIOS image for the ASUS H81M-C desktop motherboard, an Intel H81 chipset board, supplied as an 8 MB raw binary. The size corresponds to a 64 Mbit SPI flash chip, so the dump is meant to be written directly with a hardware programmer such as a CH341A when the board fails to post or the firmware is corrupted. Read and save the original chip contents before erasing, confirm the board model printed on the PCB matches, and keep in mind that a full image may carry another board's MAC address and serial data that should be restored afterwards.
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.
