BIOS archive for the MSI H270M desktop board, model MS-7A69 version 2.0, packed in a 14.1 MB RAR. MSI identifies its boards by MS-xxxx codes printed on the PCB, and the version matters since different releases can use different parts. The image is intended for recovering a board that fails to post after a bad update, by writing the SPI flash directly with a programmer. Read and keep the original chip contents first, and check that the file size matches the chip capacity.
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.
