MSI BIOS for the MS-A9231 board, version 3.0, supplied as a 536 KB ZIP. MS-A numbers are used by MSI for all-in-one and compact system boards. Because other dumps in the index cover version 2.0 of the same board, check the version marking on the PCB carefully before choosing this one. Flash it with an SPI programmer or the vendor tool to recover a board that fails to start. Save a dump of the current chip first and confirm the image size matches the flash 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.
