BIOS dump for the ASUS P8B75-V motherboard, revision 2.0 per the file name, delivered as a 6.01 MB RAR and described as fully working. A separate archive exists for version 2.01, so pick the one matching the revision silkscreened on your PCB. The image is meant to be flashed to the board SPI chip with an external programmer when the board is bricked. Read the original chip twice and compare the reads before erasing, and make sure the image length fits the installed flash part.
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.
