BIOS image for an ASUS board identified only as imp45, stored in a 417 KB RAR archive. The name gives no chip type, version or revision, so inspect the extracted file size and compare it with the flash chip on your board before writing anything. Dumps like this are flashed with an external SPI programmer to recover a board that will not POST because of corrupt firmware. Back up the original chip first and verify that the board model printed on the PCB matches imp45.
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.
