BIOS dump for the MSI H81-P33 desktop motherboard, MSI board code MS-7820, intended for an 8 MB flash chip. It is supplied as a RAR archive of 11.6 MB, which may hold more than a single image, so check what is inside before programming. MSI marks its boards with MS-xxxx numbers printed on the PCB, and that code should match. Use an SPI programmer to read and save the existing chip before writing, and confirm the extracted image is exactly 8 MB so that it fits the chip on the board.
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.
