Tested working BIOS dump for the ASUS Prime H310M-CS motherboard, revision R2.0, provided as a 4.51 MB RAR archive. The name does not give a BIOS version or chip type, so confirm the image size against the SPI flash fitted on the board. Typical use is recovering a desktop board that fails to POST by programming the chip with a CH341A or similar tool, either in circuit with a clip or after removing it. Back up the original contents first and verify the R2.0 marking on the PCB.
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.
