BIOS dump for an MSI-style board marked MS-AAA11 version 1.1, labelled as a working image by whoever saved it. It is packed in a ZIP archive of about 3.7 MB, and the name gives no device model or chip type. A dump like this is normally written to the SPI flash with a programmer such as a CH341A to revive a board that will not boot or has corrupted firmware. Compare the board number and version silkscreened on the PCB, read and keep the original contents first, and check that 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.
