BIOS image for the ASUS PRIME H310M-K motherboard, revision R2.0, reported as fully working, packed in a 7.55 MB RAR archive. The R2.0 marking matters because ASUS revisions of the same model can need different firmware, so confirm the revision printed on your PCB. Use it to recover a board with a corrupted BIOS by writing the SPI chip with an external programmer. Read and keep the original chip contents first, and verify that the image size matches the flash capacity before writing.
