Firmware dump for the MSI Z390-A PRO desktop motherboard, marked as a working BIOS. The name gives no version, board revision or flash chip details. The archive is 8.69 MB, which fits a 16 MB (128 Mbit) image after compression. Technicians write such a dump to the SPI flash with an external programmer when a board fails to POST after a bad update. Back up the existing chip contents first, and check the image length against the chip capacity, because a file of the wrong size will not fit.
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.
